Haiti - Health : 1 million vaccines against cholera arrived in the country
There is a potential risk of further spread of cholera in the departments of the South and of extension of the cases towards other departments, including Les Nippes and Ouest (Port-au-Prince).
Arrival of Vaccines and Vaccination :
22nd October: arrival of 500,000 doses in Port- au Prince
24th October: arrival of 500,000 doses in Port au Prince
Start of the campaign, 3rd November at earliest
In addition to conventional cholera control measures, a mass vaccination campaign with OCV should be organized immediately in the areas most affected by the hurricane. The decision to send 1 million doses of vaccines was taken by the Global Task Force on Cholera Control (GTFCC) partners on the 10th of October.
WHO states that the objectives of the campaign are to reduce the burden of cholera cases on health care facilities and reduce deaths in the departments affected by the hurricane and to prevent its further spread to neighbouring departments, including Port-au-Prince.
A single dose strategy will allow coverage of twice as many people as the classic 2-dose strategy. The protection would be less (60 to 70% for severe cases in adults, less among children) and of shorter duration (probably less than a year), but the objective is less to control cholera, rather to reduce its burden.
Not all the population of the departments most affected by the hurricane can be covered with 1 million dose; even with a single dose strategy (total population is estimated at 1.3 million inhabitants).
A series of inclusion criteria are proposed to define the target population :
Overall, 655 130 persons are initially targeted. All population over 1 year of age will be included.
A total of 300 000 doses will be initially kept in Port-au-Prince for additional campaigns, based on the accessibility to other communes and on the evolution of the outbreak. Those campaigns may include areas outside of the 2 departments initially targeted. 700 000 doses will be send to Sud and Grand’Anse.
