Campaign to stem the spread of the disease takes place against a backdrop of political chaos, gang violence and fuel shortages
Haiti has received its first shipment of cholera vaccines since an outbreak was declared more than two months ago.
The first of the 1.1m doses, delivered last week, will be distributed in the capital, Port-au-Prince, and surrounding areas in the hope of stemming the spread of the disease, which has been aided by political instability and lawlessness.
