Results
The population targeted showed much interest in receiving OCV after being presented with information. Of 51,814 persons surveyed during the pre-vaccination phase, 96.7% indicated their interest in receiving the vaccine.

Modeling the Effect of Water, Sanitation, and Hygiene and Oral Cholera Vaccine Implementation in Haiti

Although the 200,000 OCV doses for the 2013 campaign were purchased directly from the manufacturer by the United Nations Children’s Fund, future OCV for use in cholera-endemic and -epidemic settings will be mainly obtained through the OCV stockpile managed by the International Coordinating Group and the Global Task Force on Cholera Control (30–32). Given the limited amount of vaccine available, epidemiologic, technical, and operational evidence, as well as local capacity to conduct OCV campaigns, will be assessed for optimal stockpile vaccine use. Moreover, the International Coordinating Group highlights the need to integrate OCV use with early case detection, appropriate case management, provision of adequate WASH infrastructure, and raising of awareness in the affected communities. Therefore, the cornerstones for cholera prevention and control remain safe water, improved sanitation, and adequate hygiene; WHO recommends that OCV use should complement traditional cholera control measures, including WASH interventions (7).

"Preventing and controlling cholera transmission is a priority and requires sanitation and hygiene measures," said PAHO/WHO Representative in Haiti Jean-Luc Poncelet. "Vaccination is one more tool in the fight against this disease."

The vaccination campaign complements efforts by Haitian health authorities to improve access to safe water and sanitation, promote hand washing, and encourage community participation in cholera prevention. "The long-term goal is to eliminate cholera from Haiti," . . . 2 September 2014

. . . the root cause of cholera is in the unavailability of safe drinking water and of adequate sanitation. In Haiti, a large proportion of the population does not have access to sanitation – only 28 per cent has access to sanitation – and about half of the population has access to safe drinking water. Nobody can resolve the problem of cholera in Haiti and elsewhere until you tackle the question of sanitation . . .

. . . For vaccines to work, we also need WASH (water, sanitation and hygiene) interventions in the area. You need to provide chlorination of the surrounding areas. And finally, we have a policy of rapid response, working with the Ministry of Health . . .

 . . . The Haitian Government has asked for $2.2 billion to implement its 10-year plan to fight cholera. But to date, the plan has been less than 20 per cent funded.

Haiti’s Ministry of Health organizing a vaccination campaign against cholera in areas affected by Hurricane Matthew, supported by PAHO-WHO, UNICEF and other partners

Port-au-Prince, Haiti, 27 Oct. 2016-- The Haitian Ministry of Health (MSPP) is setting up  a vaccination campaign against cholera in areas ravaged by Hurricane Matthew, with support from the Pan American Health Organization / World Health Organization (PAHO / WHO). 

The decision of WHO and other member of the Global Task Force for Cholera Control to approve the request of the MSPP to bring 1 million doses of oral vaccine against cholera is based on the goal of reducing the burden of cholera cases on health care facilities, and of reducing deaths in the departments of the Sud and Grand'Anse, the areas most affected by Hurricane Matthew.

The target population is estimated at over 820,000 people over one year of age. The vaccination campaign will begin November 8, 2016.  Activities will focus on the municipalities most vulnerable to cholera outbreaks in the two southern departments of Grand’Anse and Sud, where there has been significant destruction of water and sanitation supply systems.
