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.
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.
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.
The etiologic agent of CHOLERA.
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.

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.
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.
Suspensions of attenuated or killed viruses administered for the prevention or treatment of infectious viral disease.
Immunoglobulins produced in a response to BACTERIAL ANTIGENS.
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.
Suspensions of attenuated or killed bacteria administered for the prevention or treatment of infectious bacterial disease.
Two or more vaccines in a single dosage form.
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.

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.
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.
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).
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.
Vaccines or candidate vaccines used to prevent PAPILLOMAVIRUS INFECTIONS.

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 the late twentieth century, oral cholera vaccines started to be used on a massive scale, with millions of vaccinations taking place, as a tool to control cholera outbreaks in addition to the traditional interventions of improving safe water supplies, sanitation, handwashing and other means of improving hygiene.[16] The Dukoral monovalent vaccine from Sweden, which combines formalin, heat-killed whole cells of Vibrio cholerae O1 and a recombinant cholera toxin B subunit, was licensed in 1991, mainly for travellers. Out of a million doses sold during the following decade, 63 negative side effects were reported.[8] The Shanchol/mORCVAX bivalent vaccine, which combines the O1 and O139 serogroups, was originally licensed in Vietnam in 1997 and given in 20 million doses to children in Vietnam during the following decade.[8] As of 2010[update], Vietnam continued to incorporate oral cholera vaccination in its public health programme, administering the vaccination through targeted mass vaccination of ...
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 ...

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 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. The authors allowed indirect effects and non-linear relationships between effect and population coverage. Because there are limited incidence data for endemic cholera in Haiti, the authors estimated the incidence of cholera over 20

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 ...
Cholera is a major public health concern in displaced-person camps, which often contend with overcrowding and scarcity of resources. Maela, the largest and longest-standing refugee camp in Thailand, located along the Thai-Burmese border, experienced four cholera outbreaks between 2005 and 2010. In 2013, a cholera vaccine campaign was implemented in the camp. To assist in the evaluation of the campaign and planning for subsequent campaigns, we developed a mathematical model of cholera in Maela. We formulated a Susceptible-Infectious-Water-Recovered-based transmission model and estimated parameters using incidence data from 2010. We next evaluated the reduction in cases conferred by several immunization strategies, varying timing, effectiveness, and resources (i.e., vaccine availability). After the vaccine campaign, we generated case forecasts for the next year, to inform on-the-ground decision-making regarding whether a booster campaign was needed. We found that preexposure vaccination can substantially
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 ...
Cholera. Cholera is rare in the United States, but its still common in some other countries. Every year, more than 100,000 people around the world die from cholera.

Summary/Abstract: This paper describes the costing of oral cholera vaccine introduction in low and middle-income countries using a publicly available Excel-based tool known as the CholTool. It includes estimates of delivery cost categories which cover not only the service delivery costs (e.g. vaccine procurement, handling, storage, and transport; vaccination administration, monitoring supervision, and field support), but also the programmatic costs associated with introducing a new vaccine (i.e. microplanning, communication and training materials development, sensitization/social mobilization, and personnel training) to ensure that a comprehensive estimate is provided with health payer perspective. CholTool takes the user through a structured sequence of interlinked modules containing input parameter cells (assumptions), decision cells (variable selections), and formulas (calculations) to produce customized cost estimates based on standardized methods. The tool provides both financial and ...

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 ...

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 ...

In December 2013, violence erupted in Juba, South Sudan, and quickly spread throughout the country. By the end of 2014, one in five persons within the country had been displaced, and many sought refuge in protection of civilians (PoC) sites inside United Nations (UN) Mission bases and in spontaneous internally displaced persons (IDP) settlements. Within 6 weeks of the start of the violence, South Sudan Ministry of Health requested vaccine from the global oral cholera vaccine stockpile to target 163,000 IDPs in 6 camps throughout the country, but not persons in the broader host communities (1).. In April 2014, two months after vaccine deployment, South Sudan confirmed the first case of cholera in the country since 2009; ≈4 weeks later, officials declared a cholera outbreak. Over 5 months, 6,269 suspected cholera cases were reported, including 156 deaths. Most cases occurred outside vaccinated camps, often in communities or camps surrounding vaccinated populations.. Several studies have ...

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 ...

Indeed, there are no drugs currently which can specifically block the cholera toxin, and so even in economically advanced countries, recovery is only ensued by oral-rehydration therapy. Nevertheless there are a multitude of clinical trials being carried out in cholera-affected areas. To find out about specific clinical trials visit: http://www.nhs.uk/Conditions/Cholera/Pages/Clinical-trial.aspx?&Condition=Cholera&pn=1&CT=0&Rec=0 .. In conclusion, always check to see if you are travelling to a cholera-affected area to ensure you take the necessary precautions. A cholera vaccine is administered as a drink and it lasts for 2 years. While in the affected area you should also avoid ice cream and any ice in drinks, ensure you drink bottled water, avoid uncooked food unless you have washed it yourself and avoid seafood. While making sure that your health is protected from cholera, we also need to support those who are disadvantaged from such privileges. The most recent severe outbreak of cholera was in ...
CNN reports on recent uptick in cholera cases worldwide CNNs the chart blog page examines the rising number of cholera cases around the world. As well as the cholera outbreak in Haiti, [a]s of this month, four African nations - Nigeria, Cameroon, Niger and Chad - possess reported a lot more than 40,000 instances of cholera and more than 2,000 deaths. Although WHO estimates there are three to five 5 million reported cholera cases and 100,000 to 120,000 deaths each year, [g]lobally, the real number of cholera cases reported to WHO continues to go up. From 2004 to 2008, cases increased by 24 % compared with the period from 2000 to 2004, according to the organization. WHO points to unclean water sources as the main source of cholera outbreaks, but also mentioned the rise in cholera instances might be due to a fresh group of variant strains detected in a number of elements of Asia and Africa.

Three leading researchers today called for the United States to create a national stockpile of cholera vaccines that could be quickly deployed to outbreaks worldwide, In an opinion article published online by the New England Journal of Medicine the researchers - Matthew Waldor, a cholera researcher at Harvard Medical School in Boston, Peter Hotez president of the Sabin Vaccine Institute in Washington DC, and John Clemens, head of the International Vaccine Institute in Seoul - argue that this could have an enormous impact in controlling cholera outbreaks, such as the current one raging in Haiti, and also serve US foreign policy interests, through vaccine diplomacy.. The question of whether vaccine could have helped in Haiti - or help in future outbreaks - is one that Ive addressed as part of a long analysis on the Haiti outbreak published in this weeks issue of Nature. Ive excerpted the relevant part in full below, which describes how those working in the field remain highly sceptical of the ...
Health and Human Services Secretary Kathleen Sebelius is in Haiti today to support two big vaccination initiatives.. One, a pilot project to prevent cholera, is already under way. The other, aimed at five childhood diseases, is set to begin later this week against .. The wider campaign aims to vaccinate 211,000 infants across the country with a five-in-one vaccine against diphtheria, tetanus, whooping cough, hepatitis B and Hib (Haemophilus influenzae type B, a cause of bacterial meningitis). Children will also get polio vaccine.. Sebeliuss personal support of the cholera campaign is surprising, since U.S. health officials have reportedly been cool to that pilot project behind the scenes.. According to Haitian health workers, American officials have expressed skepticism about the plan vaccinate 100,000 Haitians against cholera. They say U.S. officials have viewed the cholera vaccination pilot project as a distraction, and have urged Haitians to focus instead on cleaning up their water supply, ...

Ironically, for someone who has spent his entire adult life working on global infectious diseases that afflict populations in developing countries, prior to age sixteen, the farthest that he had traveled from his birthplace in New York City was to visit his mothers relatives in Baltimore, MD and Richmond, VA. Yet as a child, he voraciously read books on the history of Europe, Asia, Africa, and South America and was jokingly called a walking atlas because of his extraordinarily detailed knowledge of world geography.. Dr. Levine led the team that created the first single dose vaccine against cholera. The World Health Organization estimates there are between 1.3 and 4 million cases of cholera each year, resulting in 21,000 to 143,000 deaths worldwide. After being fast-tracked for approval by the US Food and Drug Administration, the cholera vaccine was approved in the US in 2016, as an important tool in the fight against this deadly disease..
