Global cholera vaccine supply has now increased to a level sufficient to allow the resumption of life-saving preventive campaigns for the first time in over three years, Gavi, the Vaccine Alliance, UNICEF, and the World Health Organization (WHO) announced today.

Mozambique is the first country to restart preventive vaccination, following the halt in 2022 caused by the global surge in cholera cases that drove up demand and led to shortages of oral cholera vaccine (OCV) stocks.

The preventive vaccination campaign begins amid an ongoing cholera outbreak and the aftermath of floods that affected more than 700 000 people and displaced many. The floods disrupted health systems and damaged water systems, further increasing the risk of waterborne diseases such as cholera.
