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 ...

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. 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

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 ...
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 ...

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 ...

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 ...

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.
