Ever since the first oral cholera vaccines (OCVs) appeared on the global market in 1991, many in the international health community have been skeptical about its use to control an ongoing outbreak. A major argument against reactive cholera vaccination – vaccination in response to an outbreak – was that most countries experiencing cholera outbreaks could not successfully mount vaccination campaigns quickly and that the campaign would divert time, effort and resources from more effective and longer-term measures for controlling cholera, such as improvements in water and sanitation and health education.

BACKGROUND: Despite World Health Organization (WHO) prequalification of two safe and effective oral cholera vaccines (OCV), concerns about the acceptability, potential diversion of resources, cost and feasibility of implementing timely campaigns has discouraged their use. In 2012, the Ministry of Health of Guinea, with the support of Medecins Sans Frontieres organized the first mass vaccination campaign using a two-dose OCV (Shanchol) as an additional control measure to respond to the on-going nationwide epidemic. Overall, 316,250 vaccines were delivered. Here, we present the results of vaccination coverage, acceptability and surveillance of adverse events.
