Vitamin A

Vitamin A deficiency status and indicators related to Vitamin A supplementation—such as distribution through routine services and integration with campaigns—are based on official country reporting to the World Health Organization.

Data on Vitamin A deficiency and supplementation delivered through campaigns are updated in mid-July. Data on supplementation delivered through routine services are updated and published as they are received through the WHO/UNICEF Joint Reporting Form (JRF) on Immunization.
