Cholera Vaccines: Vaccines or candidate vaccines used to prevent infection with VIBRIO CHOLERAE. The original cholera vaccine consisted of killed bacteria, but other kinds of vaccines now exist.Cholera: An acute diarrheal disease endemic in India and Southeast Asia whose causative agent is VIBRIO CHOLERAE. This condition can lead to severe dehydration in a matter of hours unless quickly treated.Cholera Toxin: An ENTEROTOXIN from VIBRIO CHOLERAE. It consists of two major protomers, the heavy (H) or A subunit and the B protomer which consists of 5 light (L) or B subunits. The catalytic A subunit is proteolytically cleaved into fragments A1 and A2. The A1 fragment is a MONO(ADP-RIBOSE) TRANSFERASE. The B protomer binds cholera toxin to intestinal epithelial cells, and facilitates the uptake of the A1 fragment. The A1 catalyzed transfer of ADP-RIBOSE to the alpha subunits of heterotrimeric G PROTEINS activates the production of CYCLIC AMP. Increased levels of cyclic AMP are thought to modulate release of fluid and electrolytes from intestinal crypt cells.Vibrio cholerae: The etiologic agent of CHOLERA.Vaccines, Inactivated: Vaccines in which the infectious microbial nucleic acid components have been destroyed by chemical or physical treatment (e.g., formalin, beta-propiolactone, gamma radiation) without affecting the antigenicity or immunogenicity of the viral coat or bacterial outer membrane proteins.Vaccines: Suspensions of killed or attenuated microorganisms (bacteria, viruses, fungi, protozoa), antigenic proteins, synthetic constructs, or other bio-molecular derivatives, administered for the prevention, amelioration, or treatment of infectious and other diseases.Vaccination: Administration of vaccines to stimulate the host's immune response. This includes any preparation intended for active immunological prophylaxis.Administration, Oral: The giving of drugs, chemicals, or other substances by mouth.Vibrio cholerae O1: Strains of VIBRIO CHOLERAE containing O ANTIGENS group 1. All are CHOLERA-causing strains (serotypes). There are two biovars (biotypes): cholerae and eltor (El Tor).Vibrio cholerae O139: Strains of VIBRIO CHOLERAE containing O ANTIGENS group 139. This strain emerged in India in 1992 and caused a CHOLERA epidemic.Immunity, Herd: The non-susceptibility to infection of a large group of individuals in a population. A variety of factors can be responsible for herd immunity and this gives rise to the different definitions used in the literature. Most commonly, herd immunity refers to the case when, if most of the population is immune, infection of a single individual will not cause an epidemic. Also, in such immunized populations, susceptible individuals are not likely to become infected. Herd immunity can also refer to the case when unprotected individuals fail to contract a disease because the infecting organism has been banished from the population.Vaccines, Synthetic: Small synthetic peptides that mimic surface antigens of pathogens and are immunogenic, or vaccines manufactured with the aid of recombinant DNA techniques. The latter vaccines may also be whole viruses whose nucleic acids have been modified.BangladeshViral Vaccines: Suspensions of attenuated or killed viruses administered for the prevention or treatment of infectious viral disease.Antibodies, Bacterial: Immunoglobulins produced in a response to BACTERIAL ANTIGENS.Vaccines, DNA: Recombinant DNA vectors encoding antigens administered for the prevention or treatment of disease. The host cells take up the DNA, express the antigen, and present it to the immune system in a manner similar to that which would occur during natural infection. This induces humoral and cellular immune responses against the encoded antigens. The vector is called naked DNA because there is no need for complex formulations or delivery agents; the plasmid is injected in saline or other buffers.Bacterial Vaccines: Suspensions of attenuated or killed bacteria administered for the prevention or treatment of infectious bacterial disease.Vaccines, Combined: Two or more vaccines in a single dosage form.Haiti: A republic in the Greater Antilles in the West Indies. Its capital is Port-au-Prince. With the Dominican Republic it forms the island of Hispaniola - Haiti occupying the western third and the Dominican Republic, the eastern two thirds. Haiti belonged to France from 1697 until its rule was challenged by slave insurrections from 1791. It became a republic in 1820. It was virtually an American protectorate from 1915 to 1934. It adopted its present constitution in 1964 and amended it in 1971. The name may represent either of two Caribbean words, haiti, mountain land, or jhaiti, nest. (From Webster's New Geographical Dictionary, 1988, p481 & Room, Brewer's Dictionary of Names, 1992, p225)Guinea: A republic in western Africa, south of SENEGAL and MALI, east of GUINEA-BISSAU. Its capital is Conakry.Antitoxins: Antisera from immunized animals that is purified and used as a passive immunizing agent against specific BACTERIAL TOXINS.AIDS Vaccines: Vaccines or candidate vaccines containing inactivated HIV or some of its component antigens and designed to prevent or treat AIDS. Some vaccines containing antigens are recombinantly produced.Vaccines, Subunit: Vaccines consisting of one or more antigens that stimulate a strong immune response. They are purified from microorganisms or produced by recombinant DNA techniques, or they can be chemically synthesized peptides.Mass Vaccination: Administration of a vaccine to large populations in order to elicit IMMUNITY.Vaccines, Conjugate: Semisynthetic vaccines consisting of polysaccharide antigens from microorganisms attached to protein carrier molecules. The carrier protein is recognized by macrophages and T-cells thus enhancing immunity. Conjugate vaccines induce antibody formation in people not responsive to polysaccharide alone, induce higher levels of antibody, and show a booster response on repeated injection.PakistanSanitation: The development and establishment of environmental conditions favorable to the health of the public.Vaccines, Attenuated: Live vaccines prepared from microorganisms which have undergone physical adaptation (e.g., by radiation or temperature conditioning) or serial passage in laboratory animal hosts or infected tissue/cell cultures, in order to produce avirulent mutant strains capable of inducing protective immunity.Malaria Vaccines: Vaccines made from antigens arising from any of the four strains of Plasmodium which cause malaria in humans, or from P. berghei which causes malaria in rodents.Immunization: Deliberate stimulation of the host's immune response. ACTIVE IMMUNIZATION involves administration of ANTIGENS or IMMUNOLOGIC ADJUVANTS. PASSIVE IMMUNIZATION involves administration of IMMUNE SERA or LYMPHOCYTES or their extracts (e.g., transfer factor, immune RNA) or transplantation of immunocompetent cell producing tissue (thymus or bone marrow).Adjuvants, Immunologic: Substances that augment, stimulate, activate, potentiate, or modulate the immune response at either the cellular or humoral level. The classical agents (Freund's adjuvant, BCG, Corynebacterium parvum, et al.) contain bacterial antigens. Some are endogenous (e.g., histamine, interferon, transfer factor, tuftsin, interleukin-1). Their mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens. The therapeutic efficacy of many biological response modifiers is related to their antigen-specific immunoadjuvanticity.Papillomavirus Vaccines: Vaccines or candidate vaccines used to prevent PAPILLOMAVIRUS INFECTIONS. Human vaccines are intended to reduce the incidence of UTERINE CERVICAL NEOPLASMS, so they are sometimes considered a type of CANCER VACCINES. They are often composed of CAPSID PROTEINS, especially L1 protein, from various types of ALPHAPAPILLOMAVIRUS.Meningococcal Vaccines: Vaccines or candidate vaccines used to prevent infection with NEISSERIA MENINGITIDIS.PhilippinesImmunoglobulin A: Represents 15-20% of the human serum immunoglobulins, mostly as the 4-chain polymer in humans or dimer in other mammals. Secretory IgA (IMMUNOGLOBULIN A, SECRETORY) is the main immunoglobulin in secretions.Antibody Formation: The production of ANTIBODIES by proliferating and differentiated B-LYMPHOCYTES under stimulation by ANTIGENS.Immunoglobulin G: The major immunoglobulin isotype class in normal human serum. There are several isotype subclasses of IgG, for example, IgG1, IgG2A, and IgG2B.Hepatitis B Vaccines: Vaccines or candidate vaccines containing inactivated hepatitis B or some of its component antigens and designed to prevent hepatitis B. Some vaccines may be recombinantly produced.Refugees: Persons fleeing to a place of safety, especially those who flee to a foreign country or power to escape danger or persecution in their own country or habitual residence because of race, religion, or political belief. (Webster, 3d ed)Diarrhea: An increased liquidity or decreased consistency of FECES, such as running stool. Fecal consistency is related to the ratio of water-holding capacity of insoluble solids to total water, rather than the amount of water present. Diarrhea is not hyperdefecation or increased fecal weight.Measles Vaccine: A live attenuated virus vaccine of chick embryo origin, used for routine immunization of children and for immunization of adolescents and adults who have not had measles or been immunized with live measles vaccine and have no serum antibodies against measles. Children are usually immunized with measles-mumps-rubella combination vaccine. (From Dorland, 28th ed)Pertussis Vaccine: A suspension of killed Bordetella pertussis organisms, used for immunization against pertussis (WHOOPING COUGH). It is generally used in a mixture with diphtheria and tetanus toxoids (DTP). There is an acellular pertussis vaccine prepared from the purified antigenic components of Bordetella pertussis, which causes fewer adverse reactions than whole-cell vaccine and, like the whole-cell vaccine, is generally used in a mixture with diphtheria and tetanus toxoids. (From Dorland, 28th ed)Haemophilus Vaccines: Vaccines or candidate vaccines containing antigenic polysaccharides from Haemophilus influenzae and designed to prevent infection. The vaccine can contain the polysaccharides alone or more frequently polysaccharides conjugated to carrier molecules. It is also seen as a combined vaccine with diphtheria-tetanus-pertussis vaccine.Rural Population: The inhabitants of rural areas or of small towns classified as rural.BCG Vaccine: An active immunizing agent and a viable avirulent attenuated strain of Mycobacterium tuberculosis, var. bovis, which confers immunity to mycobacterial infections. It is used also in immunotherapy of neoplasms due to its stimulation of antibodies and non-specific immunity.Tanzania: A republic in eastern Africa, south of UGANDA and north of MOZAMBIQUE. Its capital is Dar es Salaam. It was formed in 1964 by a merger of the countries of TANGANYIKA and ZANZIBAR.Poliovirus Vaccine, Inactivated: A suspension of formalin-inactivated poliovirus grown in monkey kidney cell tissue culture and used to prevent POLIOMYELITIS.Rabies Vaccines: Vaccines or candidate vaccines used to prevent and treat RABIES. The inactivated virus vaccine is used for preexposure immunization to persons at high risk of exposure, and in conjunction with rabies immunoglobulin, for postexposure prophylaxis.Antibody-Producing Cells: Cells of the lymphoid series that can react with antigen to produce specific cell products called antibodies. Various cell subpopulations, often B-lymphocytes, can be defined, based on the different classes of immunoglobulins that they synthesize.Rotavirus Vaccines: Vaccines or candidate vaccines used to prevent infection with ROTAVIRUS.Travel Medicine: Multidisciplinary field focusing on prevention of infectious diseases and patient safety during international TRAVEL. Key element of patient's pre-travel visit to the physician is a health risk assessment.Travel: Aspects of health and disease related to travel.Meningitis, Meningococcal: A fulminant infection of the meninges and subarachnoid fluid by the bacterium NEISSERIA MENINGITIDIS, producing diffuse inflammation and peri-meningeal venous thromboses. Clinical manifestations include FEVER, nuchal rigidity, SEIZURES, severe HEADACHE, petechial rash, stupor, focal neurologic deficits, HYDROCEPHALUS, and COMA. The organism is usually transmitted via nasopharyngeal secretions and is a leading cause of meningitis in children and young adults. Organisms from Neisseria meningitidis serogroups A, B, C, Y, and W-135 have been reported to cause meningitis.

Expanded safety and immunogenicity of a bivalent, oral, attenuated cholera vaccine, CVD 103-HgR plus CVD 111, in United States military personnel stationed in Panama. (1/263)

To provide optimum protection against classical and El Tor biotypes of Vibrio cholerae O1, a single-dose, oral cholera vaccine was developed by combining two live, attenuated vaccine strains, CVD 103-HgR (classical, Inaba) and CVD 111 (El Tor, Ogawa). The vaccines were formulated in a double-chamber sachet; one chamber contained lyophilized bacteria, and the other contained buffer. A total of 170 partially-immune American soldiers stationed in Panama received one of the following five formulations: (a) CVD 103-HgR at 10(8) CFU plus CVD 111 at 10(7) CFU, (b) CVD 103-HgR at 10(8) CFU plus CVD 111 at 10(6) CFU, (c) CVD 103-HgR alone at 10(8) CFU, (d) CVD 111 alone at 10(7) CFU, or (e) inactivated Escherichia coli placebo. Among those who received CVD 111 at the high or low dose either alone or in combination with CVD 103-HgR, 8 of 103 had diarrhea, defined as three or more liquid stools. None of the 32 volunteers who received CVD 103-HgR alone or the 35 placebo recipients had diarrhea. CVD 111 was detected in the stools of 46% of the 103 volunteers who received it. About 65% of all persons who received CVD 103-HgR either alone or in combination had a fourfold rise in Inaba vibriocidal titers. The postvaccination geometric mean titers were comparable among groups, ranging from 450 to 550. Ogawa vibriocidal titers were about twice as high in persons who received CVD 111 as in those who received CVD 103-HgR alone (600 versus 300). The addition of CVD 111 improved the overall seroconversion rate and doubled the serum Ogawa vibriocidal titers, suggesting that the combination of an El Tor and a classical cholera strain is desirable. While CVD 111 was previously found to be well tolerated in semiimmune Peruvians, the adverse effects observed in this study indicate that this strain requires further attenuation before it can be safely used in nonimmune populations.  (+info)

Antibody responses in the lower respiratory tract and male urogenital tract in humans after nasal and oral vaccination with cholera toxin B subunit. (2/263)

Nasal vaccine delivery is superior to oral delivery in inducing specific immunoglobulin A (IgA) and IgG antibody responses in the upper respiratory tract. Although an antibody response in the nasal passages is important in protecting against primary colonization with lung pathogens, antibodies in the lungs are usually required as well. We immunized 15 male volunteers twice nasally or orally with cholera toxin B subunit (CTB) and determined the specific antibody levels in serum, bronchoalveolar lavage (BAL) fluid, and urine before and 2 weeks after immunization. Nasal immunization induced fivefold increases in the levels of specific IgA antibodies in BAL fluid of most volunteers, whereas there were no significant specific IgA responses after oral immunization. The specific IgG antibody level increased eightfold in BAL fluid in the nasally vaccinated subjects, and the major part of IgG had most probably been transferred from serum. Since the specific IgG response in serum was lower in the individuals vaccinated orally, the IgG response in BAL fluid in this group was also lower and not significant. In conclusion, nasal immunization is also preferable to the oral route when vaccinating against lower respiratory tract infections, and a systemic immune response is considerably more important in the lower than in the upper respiratory tract. Moreover, both nasal and oral immunizations were able to stimulate 6- to 10-fold specific IgA and IgG responses in urine in about half of the individuals, which indicates that distant mucosal vaccination might be used to prevent adhesion of pathogens to the urogenital tract.  (+info)

Mucosal and systemic immune responses in humans after primary and booster immunizations with orally administered invasive and noninvasive live attenuated bacteria. (3/263)

The mucosal and systemic immune responses after primary and booster immunizations with two attenuated live oral vaccine strains derived from a noninvasive (Vibrio cholerae) and an invasive (Salmonella typhi) enteric pathogen were comparatively evaluated. Vaccination with S. typhi Ty21a elicited antibody-secreting cell (ASC) responses specific for S. typhi O9, 12 lipopolysaccharide (LPS), as well as significant increases in levels of immunoglobulin G (IgG) and IgA antibodies to the same antigen in serum. A strong systemic CD4(+) T-helper type 1 cell-mediated immune (CMI) response was also induced. In contrast to results with Ty21a, no evidence of a CMI response was obtained after primary immunization with V. cholerae CVD 103-HgR in spite of the good immunogenicity of the vaccine. Volunteers who received a single dose of CVD 103-HgR primarily developed an IgM ASC response against whole vaccine cells and purified V. cholerae Inaba LPS, and seroconversion of serum vibriocidal antibodies occurred in four of five subjects. Serum IgG anti-cholera toxin antibody titers were of lower magnitude. For both live vaccines, the volunteers still presented significant local immunity 14 months after primary immunization, as revealed by the elevated baseline antibody titers at the time of the booster immunization and the lower ASC, serum IgG, and vibriocidal antibody responses after the booster immunization. These results suggest that local immunity may interfere with colonization of the gut by both vaccine strains at least up to 14 months after basis immunization. Interestingly, despite a low secondary ASC response, Ty21a was able to boost both humoral (anti-LPS systemic IgG and IgA) and CMI responses. Evidence of a CMI response was also observed for one of three volunteers given a cholera vaccine booster dose. The direct comparison of results with two attenuated live oral vaccine strains in human volunteers clearly showed that the capacity of the vaccine strain to colonize specific body compartments conditions the pattern of vaccine-induced immune responses.  (+info)

Effect of small bowel bacterial overgrowth on the immunogenicity of single-dose live oral cholera vaccine CVD 103-HgR. (4/263)

Several live oral vaccines (polio, bovine rotavirus, CVD 103-HgR cholera) are less immunogenic in developing than in industrialized countries. It was hypothesized that proximal small bowel bacterial overgrowth (common in children in less developed countries but rare in industrialized settings) diminishes the vibriocidal antibody response to CVD 103-HgR. In total, 202 fasting Santiago schoolchildren aged 5-9 years had lactulose breath H2 tests to detect proximal small bowel bacteria 1 day before ingesting CVD 103-HgR. Florid small bowel overgrowth was observed in 10 (5.6%) of 178 analyzable children. In children with florid overgrowth, vibriocidal seroconversion differed little from other children (60% vs. 67%), but the geometric mean titer was lower (160 vs. 368; P=.25). By logistic regression, increased peak breath H2 at small bowel time points was associated with diminished seroconversion (P=.04), as was the interaction of H2 value and weight (children >25 kg had lower seroconversion rates among subjects with heaviest overgrowth).  (+info)

Randomized, double-blind, placebo-controlled, multicentered trial of the efficacy of a single dose of live oral cholera vaccine CVD 103-HgR in preventing cholera following challenge with Vibrio cholerae O1 El tor inaba three months after vaccination. (5/263)

CVD 103-HgR is a live oral cholera vaccine strain constructed by deleting 94% of the gene for the enzymatically active A subunit of cholera toxin from classical Inaba Vibrio cholerae O1 569B; the strain also contains a mercury resistance gene as an identifying marker. This vaccine was well tolerated and immunogenic in double-blind, controlled studies and was protective in open-label studies of volunteers challenged with V. cholerae O1. A randomized, double-blind, placebo-controlled, multicenter study of vaccine efficacy was designed to test longer-term protection of CVD 103-HgR against moderate and severe El Tor cholera in U.S. volunteers. A total of 85 volunteers (50 at the University of Maryland and 35 at Children's Hospital Medical Center/University of Cincinnati) were recruited for vaccination and challenge with wild-type V. cholerae El Tor Inaba. Volunteers were randomized in a double-blind manner to receive, with buffer, a single oral dose of either CVD 103-HgR (2 x 10(8) to 8 x 10(8) CFU) or placebo (killed E. coli K-12). About 3 months after immunization, 51 of these volunteers were orally challenged with 10(5) CFU of virulent V. cholerae O1 El Tor Inaba strain N16961, prepared from a standardized frozen inoculum. Ninety-one percent of the vaccinees had a >/=4-fold rise in serum vibriocidal antibodies after vaccination. After challenge, 9 (39%) of the 23 placebo recipients and 1 (4%) of the 28 vaccinees had moderate or severe diarrhea (>/=3-liter diarrheal stool) (P < 0.01; protective efficacy, 91%). A total of 21 (91%) of 23 placebo recipients and 5 (18%) of 28 vaccinees had any diarrhea (P < 0.001; protective efficacy, 80%). Peak stool V. cholerae excretion among placebo recipients was 1.1 x 10(7) CFU/g and among vaccinees was 4.9 x 10(2) CFU/g (P < 0.001). This vaccine could therefore be a safe and effective tool to prevent cholera in travelers.  (+info)

Mass vaccination with a two-dose oral cholera vaccine in a refugee camp. (6/263)

In refugee settings, the use of cholera vaccines is controversial since a mass vaccination campaign might disrupt other priority interventions. We therefore conducted a study to assess the feasibility of such a campaign using a two-dose oral cholera vaccine in a refugee camp. The campaign, using killed whole-cell/recombinant B-subunit cholera vaccine, was carried out in October 1997 among 44,000 south Sudanese refugees in Uganda. Outcome variables included the number of doses administered, the drop-out rate between the two rounds, the proportion of vaccine wasted, the speed of administration, the cost of the campaign, and the vaccine coverage. Overall, 63,220 doses of vaccine were administered. At best, 200 vaccine doses were administered per vaccination site and per hour. The direct cost of the campaign amounted to US$ 14,655, not including the vaccine itself. Vaccine coverage, based on vaccination cards, was 83.0% and 75.9% for the first and second rounds, respectively. Mass vaccination of a large refugee population with an oral cholera vaccine therefore proved to be feasible. A pre-emptive vaccination strategy could be considered in stable refugee settings and in urban slums in high-risk areas. However, the potential cost of the vaccine and the absence of quickly accessible stockpiles are major drawbacks for its large-scale use.  (+info)

Optimizing the germfree mouse model for in vivo evaluation of oral Vibrio cholerae vaccine and vector strains. (7/263)

The germfree mouse model of Vibrio cholerae infection can be used to judge immune responses to V. cholerae vaccine and vector strains. In the original model, a single oral inoculation was administered on day 0, a booster oral inoculation was administered on day 14, and immune responses were analyzed with samples collected on day 28. Unfortunately, immune responses in this model frequently were low level, and interanimal variability occurred. In order to improve this model, we evaluated various primary and booster V. cholerae inoculation schedules. The most prominent systemic and mucosal antibody responses were measured in mice that received a multiple primary inoculation series on days 0, 2, 4, and 6 and booster inoculations on days 28 and 42. These modifications result in improved preliminary evaluation of V. cholerae vaccine and vector strains in mice.  (+info)

Use of lambda phage S and R gene products in an inducible lysis system for Vibrio cholerae- and Salmonella enterica serovar typhimurium-based DNA vaccine delivery systems. (8/263)

Novel methods for adapting DNA vaccine technology to the prevention of mucosal diseases are greatly needed. Here we show that regulated expression of phage lambda lysis genes S and R causes dramatic lysis of both Vibrio cholerae and Salmonella enterica serovar Typhimurium cells with concomitant release of plasmid DNA into the surrounding media. We also used single and double DNase mutant strains to show that secreted V. cholerae DNases can adversely affect the integrity of DNA molecules released upon lysis. These results suggest that incorporation of lambda SR-mediated lysis constructs and DNA stabilizing mutations into candidate live attenuated bacterial vaccines offers a promising approach for the development of effective mucosal DNA delivery vectors for humans.  (+info)

N2 - Background: Decisions about the use of killed oral cholera vaccines, which confer moderate levels of direct protection to vaccinees, can depend on whether the vaccines also provide indirect (herd) protection when high levels of vaccine coverage are attained. We reanalysed data from a field trial in Bangladesh to ascertain whether there is evidence of indirect protection from killed oral cholera vaccines. Methods: We analysed the first year of surveillance data from a placebo-controlled trial of B subunit-killed whole-cell and killed whole-cell-only oral cholera vaccines in children and adult women in Bangladesh. We calculated whether there was an inverse, monotonic trend for the relation ...
Author Summary Cholera outbreaks have had catastrophic impact on societies for centuries. Despite more than half a century of advocacy for safe water, sanitation and hygiene, approximately 100,000 cholera cases and 5,000 deaths were reported in Zimbabwe between August 2008 and by July 2009. Safe and effective oral cholera vaccines have been licensed and used by affluent tourists for more than a decade to prevent cholera. We asked whether oral cholera vaccines could be used to protect high risk populations at a time of cholera. We calculated how many cholera cases could have been prevented if mass cholera vaccinations would have been implemented in reaction to past cholera outbreaks. We estimate that determined, well organized mass vaccination campaigns could have prevented 34,900 (40%) cholera cases and 1,695 deaths (40%) in Zimbabwe. In the sites with endemic cholera, Kolkata and Zanzibar, a significant number of cases could have been prevented but the impact would have been less dramatic. The barriers
In addition to improved water supply and sanitation, the two-dose killed oral cholera vaccine (OCV) is an important tool for the prevention and control of cholera. We aimed to document the immunogenicity and protection (efficacy and effectiveness) conferred by a single OCV dose against cholera. The meta-analysis showed an estimated 73% and 77% of individuals seroconverted to the Ogawa and Inaba serotypes, respectively, after an OCV first dose. The estimates of single-dose vaccine protection from available studies are 87% at 2 months decreasing to 33% at 2 years. Current immunologic and clinical data suggest that protection conferred by a single dose of killed OCV may be sufficient to reduce short-term risk in outbreaks or other high-risk settings, which may be especially useful when vaccine supply is limited. However, until more data suggests otherwise, a second dose should be given as soon as circumstances allow to ensure robust protection.. ...
January 3, 2014. California-based vaccine manufacturer PaxVax has reportedly submitted an application to begin international trials of a novel oral cholera vaccine that contains live, genetically modified (GM) bacteria. VacTruth.com reports that the new vaccine is set to be tested on more than 1,000 individuals, many of whom are young children, in a three-part clinical trial series to take place throughout Australia.. In a recent application filing with the Australian Government, PaxVax makes plain its intent to administer the live, GM bacteria in both young and old and in every region of the country. Participants will be instructed to literally consume a cocktail of mercury-resistant, GM Shigella flexneri NR1 bacteria derived from the Vibrio cholera bacterial strain, which is recognized as the causative agent of the gastroenteritis disease known as cholera.. According to the filing, the GM cholera strain used in the vaccine has essentially been artificially neutralized to prevent the toxic ...
As the world faced a dearth of oral cholera vaccines, the United Nations health agency announced that the supply of medication will double up to six million doses this year after it added another producer to its list of approved suppliers so that they can put up a fight against a disease that kills as many as 142,000 people every year
Sharing results of the clinical study, Dr. Ajit Pal Singh- Vice President Clinical R&Dat Hilleman Labsstated, "HillcholTM was tested in 840 subjects that included adults, adolescents as well as small children. We were able to demonstrate safety and tolerability of HillcholTM in our Phase I/II trials. Our vaccine consists of a novel Hikojima strain that expresses both the Ogawa and Inaba serotypes. When compared against Shanchol, the Cholera vaccine pre-qualified by WHO, we could achieve non-inferiority in terms of seroconversion as well as Geometric Mean Titre for both the Ogawa and Inaba serotypes. These results are very encouraging and warrant further development of our Cholera vaccine.". Dr. Tarun Sharma, Director R&D at Hilleman Labsstated, "The HillcholTM Phase I/II clinical trial results support our Hikojima vaccine design and mirror the impressive results we have been able to achieve in Preclinical studies. This encourages us to conduct further clinical studies as well as undertake ...
Abstract. Successful and sustained efforts have been made to curtail the major cholera epidemic that occurred in Haiti in 2010 with the promotion of hygiene and sanitation measures, training of health personnel and establishment of treatment centers nationwide. Oral cholera vaccine (OCV) was introduced by the Haitian Ministry of Health as a pilot project in urban and rural areas. This paper reports the successful OCV pilot project led by GHESKIO Centers in the urban slums of Port-au-Prince where 52,357 persons received dose 1 and 90.8% received dose 2; estimated coverage of the at-risk community was 75%. This pilot study demonstrated the effort, community mobilization, and organizational capacity necessary to achieve these results in a challenging setting. The OCV intervention paved the way for the recent launching of a national cholera vaccination program integrated in a long-term ambitious and comprehensive plan to address Haiti's critical need in water security and sanitation.

I can give two: one where we responded to prevent cholera and another where oral cholera vaccine (OCV) was used to contain it. Firstly, in 2014 there was an influx of refugees from South Sudan into the Gambella region of Ethiopia. In Gambella at that time there had been no cholera reported for years, but we knew there was cholera in South Sudan. Together with MSF, WHO and the national health partner (ARRA) we were able to make a strong case for oral cholera vaccination of the refugee population and surrounding host communities. If cholera came it could be contained - we wanted to make sure we were ahead of the curve. Through some good joint advocacy with partners and donors, we were able to get it approved and the Minister of Health supported it. We implemented it, and no cholera cases were reported during that acute emergency. The second example is in Tanzania, where we had a cholera outbreak. This was an emergency in 2015 with refugees coming from Burundi, and we had a cholera outbreak around ...
A third producer of oral cholera vaccine has been approved that is expected to provide 3 million doses in 2016, the World Health Organization said on Friday, doubling the worlds stockpile against a disease that can kill within hours.
A CDC collaborative study including Dr. Isaac Fung (formerly of the CDC), assistant professor of epidemiology at Georgia Southern University Jiann-Ping Hsu College of Public Health, examines preventive interventions through modeling the effect of water, sanitation and hygiene, and oral cholera vaccine implementation in Haiti. In 2010, toxigenic Vibrio cholerae was newly introduced to Haiti. Because resources are limited, decision-makers need to understand the effect of different preventive interventions. The team built a static model to estimate the potential number of cholera cases averted through improvements in coverage in water, sanitation and hygiene (WASH) (i.e., latrines, point-of-use chlorination, and piped water), oral cholera vaccine (OCV), or a combination of both.

Cholera is rare in the U.S. and other areas of the world that have good water and sewage (waste) systems. However, it is a problem in parts of the world that do not have such systems. If you are traveling to cholera-infected areas (eg, developing countries of Africa, Asia, and Latin America) cholera vaccine may help protect you from cholera. It is very important to avoid infected persons and food and water that may be infected, even if you have received the vaccine. This vaccine is to be given only by or under the supervision of a doctor. This product is available in the following dosage forms:. ...

By Makini Brice | LES CAYES, Haiti LES CAYES, Haiti Haiti has launched a massive cholera vaccination campaign to battle a flare-up after Hurricane Matthew, but concerns remain about the capacity for longer-term improvements to water and sanitation infrastructure needed to eradicate the disease. The cholera campaign, launched on Tuesday in two southern areas hammered by the storm, is aiming to be the worlds largest, targeting 820,000 people, said Ernsly Jackson, an immunization specialist for UNICEF Haiti. Haiti has battled a cholera outbreak that has sickened more than 800,000 people and killed about 9,000 since 2010, when the bacteria was imported into the country by a contingent of United Nations peacekeepers. Although it had proved stubborn to eradicate, cases had declined sharply from a peak in 2010-11. But Hurricane Matthew struck the island in early October, killing up to 1,000 people, leaving about 1.4 million in need of humanitarian assistance and damaging many health facilities.
Three health experts have recommended that the United States begin creating a stockpile of cholera vaccines so that they could be rapidly deployed to areas with major cholera outbreaks like the current one in Haiti.

Cholera is an acute dehydrating diarrheal disease caused by Vibrio cholerae, endemic in over 50 countries, and affecting over 3 million people each year. Currently available oral cholera vaccines have a lower efficacy and shorter duration of protection in young children compared to adults. Funded by the NIAID, and in collaboration with colleagues at the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b), we are investigating the immune responses of children following both wild type cholera infection and cholera vaccination. We have identified a number of major differences between infection and vaccination, specifically pertaining to memory B cells, memory T cells, innate T cells, antibody avidity, and polysaccharide-specific responses. We are interested in how these factors differ between children and adults, and the impact of host factors, such as malnutrition, micronutrient deficiency, and enteropathy, on these responses. We have recently begun a collaboration with ...
Trials of the oral cholera vaccine that contained inactivated whole-cell V. cholerae O1 combined with rCTB have been performed mainly in Bangladesh and Peru.8-14The large randomised controlled trial in Bangladesh included over 120 000 children (aged 2-15 years) and women (aged ,15 years), with up to 5 years follow-up. About 13 000 children and 8 000 women received 3 doses of the study vaccine. When cholera cases in all age groups were aggregated, the protective efficacy of this vaccine (in a 3-dose regimen with inactivated Escherichia coli as control) was 85%, 6 months after the 3rd dose. The protective efficacy decreased to 62% after 1 year, and to 57% after 2 years.8,10 On long-term follow-up (up to 5 years) no significant protective efficacy was observed beyond 2 years.8,14 The efficacy of the vaccine was lower and waned more rapidly in children aged 2-5 years.14 In this age group, while the efficacy was 100% during the first 4-6 months after vaccination, it became non-significant in the ...
A pilot program to vaccinate 100,000 Haitians against cholera this past spring reached almost 90% of the target population with the full two-dose regimen, National Public Radio (NPR) reported yesterday. The effort far surpassed the predictions of skeptics who had said that it would be lucky to vaccinate 60% of the target groups, according to the story. The nonprofit medical groups that sponsored the project-GHESKIO and Partners in Health-presented the results Jul 16 to Haitis health minister, Florence Guillaume, MD. The two groups said the success of the program has done much to counter doubts about vaccination as part of the strategy for fighting cholera in Haiti, which has had about 560,000 cases and 7,300 deaths since the fall of 2010. The government previously opposed vaccination, saying resources should be used to treat the sick and improve water and sanitation. But Jean William Pape, MD, of GHESKIO told NPR, "The minister of health is convinced that, based on these results, at-risk ...

Mass cholera vaccinations in Rohingyas refugee camps (AhlulBayt News Agency) - Amid fears of an outbreak among nearly a million Rohingya now living in the vast refugee camps of southeast Bangladesh, the United Nations launched one of its biggest ever cholera vaccination drives Tuesday.
During the days of late Sarvodayam Kurian, it was difficult to contain the epidemic due to limited medical care access. Kurian initiated the free cholera vaccine scheme through the support of Government Health Department. With help of several youth from the Island, Kurian educated the public on the need of taking the preventive vaccination. They used to visit all major junctions of the Island and announce the place, date and the time when free vaccine would be provided. Punctually arriving on his bicycle, Kurian would supervise the vaccination of thousands of Islanders. This immensely helped control the epidemic and save several lives.. During the time of cholera epidemic, especially in 1964 and 1982, the unfortunate victims were left with hardly any health care as there were only three primary health centres for a few million inhabitants. People died like flies. Even family members were afraid of burying their diseased for fear of contracting deadly cholera. Kurian would pick up the dead body ...

Innate immune responses to V. cholerae infection have not been intensely studied in part due to the absence of a murine model for pathogenesis. The suckling mouse model has proven useful for the study of bacterial colonization and regulation of virulence factors (37). However, these 5-6-d-old mice do not have immune systems sufficiently developed for study of immunomodulation. Adult germ-free mouse models have been useful for evaluation of immunogenic potential of oral V. cholerae vaccine strains even though colonization may not occur (38), yet neither of these models is applicable for study of acute inflammatory responses. In this study, we report the use of a novel mouse model conceptually adapted from the studies of S. flexneri (30-32) and technically based on previous studies with Pseudomonas aeruginosa (39). We have demonstrated that V. cholerae can infect the lung of BALB/c mice leading to the development of inflammation.. The identity of the "reactogenicity factor" of V. cholerae vaccine ...

Cholera remains a substantial contributor to public health burden in many developing countries, particularly in sub-Sahara Africa. In 2014, 190,549 cases were reported to the World Health Organization (WHO), including 55% from Africa [1]. Of the 2,231 deaths reported worldwide, 1882 (84.4%) occurred in Africa. However, the true burden of cholera is poorly known and likely underestimated, because of limitations in current national surveillance systems including under-reporting, type of case-definitions used and lack of laboratory diagnostic capacities. An estimated 2.9 million cholera cases (1.3 m-4.0 m) and 95,000 cholera deaths (21,000-143,000) occur each year [2].. Targeting cholera prevention through increased access to water, sanitation and hygiene (WASH) and oral cholera vaccines (OCV) requires accurate epidemiological data at the local level. Further, such data help international organizations to prioritize where to support the places most in need.. The African Cholera Surveillance Network ...
The potential of peptide mimics of V. cholerae lipopolysaccharide (LPS) to elicit cross-reactive immune responses against LPS was investigated, as an alternative approach towards the development of a cholera vaccine. Peptide mimics of two protective epitopes were identified. Peptide mimics were identified by screening phage display libraries with two closely related Ogawa serotype specific (monoclonal antibodies) mAbs, S-20-4 and A-20-6 and novel protective mAb 72.1 that cross-reacts with both Inaba and Ogawa serotypes. Six phage clones identified from the S-20-4 panning showed significant binding to both S-20-4 and A-20-6. Thus, it is likely that these phage displayed peptides mimic an important conformational epitope of Ogawa antigens and are not simply functionally recognized by S-20-4. In order to predict how Ogawa peptide mimics interact with S-20-4 compared to its carbohydrate counterpart, one peptide mimic, 4P-8, which is one of the highest affinity binders to anti-LPS Abs and shares ...

CVD 103-HgR (Vaxchora, PaxVax) cholera vaccine was approved by the Food and Drug Administration in June 2016. ACIP has not yet published recommendations for Vaxchora. However, at their June 2016 meeting, ACIP voted to recommend vaccination for adults 18 through 64 years old traveling to areas of active cholera transmission. An area of active cholera transmission is defined as a province, state, or other administrative subdivision within a country with endemic or epidemic cholera caused by toxigenic V. cholerae O1 and includes areas with cholera activity within the last 1 year that are prone to recurrence of cholera epidemics; it does not include areas where rare sporadic cases have been reported. No country or territory currently requires vaccination against cholera as a condition for entry. ...
We are excited that Vaxchora is now available to Americans traveling to areas affected by cholera. This is particularly timely in light of the number of U.S. citizens, including members of the U.S. military, joining relief efforts in Haiti," said Nima Farzan, chief executive officer and president of PaxVax. "Vaccinating those traveling to cholera-affected areas can help mitigate its spread and can help protect them against the disease," said Farzan.. Vaxchora is approved for use in U.S. residents 18 through 64 years of age. The effectiveness of Vaxchora has not been established in persons living in cholera-affected areas or in persons who have pre-existing immunity due to previous exposure to V. cholerae or receipt of a different cholera vaccine available in other countries.. Vaxchora is not approved for use outside of the United States.. The FDA approval of Vaxchora is based on positive results from a 10 and 90-day cholera challenge trial, as well as two safety and immunogenicity trials in ...

It has been roughly eight months since cholera first took hold in war-torn Yemen. In that brief span, the waterborne disease has exacted a staggering toll
Another aspect of cholera that was not understood was why its virulence varied greatly from strain to strain. Some strains even failed to produce disease. Cholera toxin, an enzyme, was eventually identified as the main virulence factor associated with strains that induced acute diarrhea. Cholera toxin is synthesized and secreted by strains in the 01 and 0139 groups, only. Those lacking this enzyme are far less pathogenic. Its mode of action eventually results in prolonged hypersecretion in the small intestine. The diarrhea is so intense that enterocytes become fragile and begin to sluff off from the basement membrane of the villus soon after symptoms appear.. Cholera toxin attaches at the level of the crypts of Lieberkühn to enterocytes that have surface ganglioside Gm1, a special glycolipid. Internalization of the toxin-ganglioside complex then occurs. The bacterial enzyme catalyses the transfer of ADP ribose from intracellular NAD+ to the s subunit of the trimeric G protein that is normally ...

What is vaccination?. Vaccination provides immunity to specific diseases. A person who had been vaccinated has artificial immunity. This is created by deliberate exposure to antigenic material that has been rendered harmless. The immune system treats the antigenic material, as a real disease. As a result, the immune system manufactures antibodies and memory cells. The memory cells provide the long-term immunity.. The antigenic material used in vaccinations can take a variety of forms:. · Whole, live microorganisms - usually ones that are not as harmful as those that cause the real disease. But they must have similar antigens so that the antibodies produced will be effective against the real pathogen (e.g. the smallpox vaccine).. · A harmless or attenuated version of the pathogenic organism (e.g. measles and TB vaccines). · A dead pathogen (e.g. typhoid and cholera vaccines).. · A preparation of the antigens from a pathogen (e.g. hepatitis B vaccine).. · Some harmless toxin (called a toxoid) ...
A cholera outbreak in war-ravaged Yemen has killed 242 people, and left nearly 23,500 others sick in the past three weeks alone, the World Health Organization said Friday. The UN health agency said that in the past day alone, 20 cholera deaths and 3,460 suspected cases had been registered in the country, where two-thirds of the population is on the brink of famine. "The speed of the resurgence of this cholera epidemic is unprecedented," WHO representative for Yemen Nevio Zagaria told reporters in Geneva by phone from Yemen, warning that a quarter of a million people could become sick by the end of the year. Cholera is a highly contagious bacterial infection spread through contaminated food or water. Reining in the disease is particularly complicated in Yemen, where two years of devastating war between the Huthis and government forces backed by a Saudi-led Arab military coalition has left more than half the country`s medical facilities out of service. Zagaria pointed out that humanitarian workers ...

This 5.5" x 9" (13.97 x 13.97 cm), 64-page pamphlet written by Joel Roberts recounts the 1849 cholera epidemic in Sandusky. The last five pages of the diary list people who died in the epidemic. Cholera was a major threat in the 19th century. Due to poor sanitation and ignorance of the causes of disease, Sandusky suffered several cholera outbreaks in the 1840s and 1850s. The most devastating outbreak occurred in the summer of 1849, when 400 people died and many more fled the city in fear. The citys population before the outbreak was about 5,000; it is estimated that fewer than 1,000 remained in the city during the cholera. The 1882 History of Sandusky County reported that "medical men [were] taxed to their utmost to stem the tide of disease and death." The devastation caused by cholera and other epidemics helped to inspire improvements in medical care, research, and sanitation practices such as water treatment ...

Interesting facts about cholera disease - What sort of disease is cholera? Bacterial infection. Cholera is caused by a bacterium, vibrio cholerae. Infections results in severe profuse watery diarrhea and may cause death from dehydration. The bacterium is usually transmiited through water or food.
Vibrio cholerae O139 has recently emerged as the second etiologic agent of cholera in Asia. A study was carried out to evaluate the induction of specific immune responses to the organism in V. cholerae O139-infected patients. The immune responses to V. cholerae O139 Bengal were studied in patients by measuring antibody-secreting cells (ASC), as well as vibriocidal and antitoxic antibodies in the circulation. These responses were compared with those in patients with V. cholerae O1 disease. Strong immunoglobulin A (IgA) and IgM ASC responses were seen against the homologous lipopolysaccharide or serogroup of V. cholerae. The magnitude and isotype of the responses were similar in O139- and O1-infected patients. Vibriocidal antibody responses were seen against bacteria of the homologous but not heterologous serogroup, and these responses reflect the lack of cross-protection between the infections caused by the two serogroups. The two groups of patients showed comparable cholera toxin-specific ASC ...

Since mid-August 1986, 12 cases of cholera have been identified among residents of Louisiana. The cases occurred in nine families living in New Orleans and in other towns in six parishes (Jefferson, LaFourche, Assumption, St. Mary, Iberia, and Jefferson Davis) within a 200-mile radius to the south and west of New Orleans. None of the patients had traveled abroad within the past year. Onset of symptoms occurred between August 8 and October 1. Ten of the patients had severe diarrhea, seven required hospitalization, and four required treatment in an intensive care unit for hypotension. All patients recovered following intravenous fluid therapy. Seven patients had stool cultures yielding toxigenic Vibrio cholerae O1, biotype El Tor, serotype Inaba. The remaining five patients did not have stool cultures performed but had vibriocidal antibody titers greater than or equal to 1280, suggesting recent infection with V. cholerae O1. Sewer system surveillance using Moore swabs has detected toxigenic V. ...

One of the goals of this study was to learn the coverage, safety and logistics of a mass vaccination campaign against typhoid fever in children and adults using locally produced typhoid Vi polysaccharide (PS) and group A meningococcal PS vaccines in southern China. The vaccination campaign targeted 118,588 persons in Hechi, Guangxi Province, aged between 5 to 60 years, in 2003. The study area was divided into 107 geographic clusters, which were randomly allocated to receive one of the single-dose parenteral vaccines. All aspects regarding vaccination logistics, feasibility and safety were documented and systematically recorded. Results of the logistics, feasibility and safety are reported. The campaign lasted 5 weeks and the overall vaccination coverage was 78%. On average, the 30 vaccine teams gave immunizations on 23 days. Vaccine rates were higher in those aged ≤ 15 years (90%) than in adolescents and young adults (70%). Planned mop-up activities increased the coverage by 17%. The overall vaccine
