UNICEF and WHO supported the Ministry of Health of Iraq (MoH) in conducting a nationwide multi-antigen vaccination campaign. The campaign reached more than 400,000 of the most vulnerable children with over one million doses of different vaccines, to protect them against vaccine-preventable diseases.

The locations covered by the ten-day campaign, which concluded at the end of 2022 were based on a risk assessment carried out by the MoH, also supported by UNICEF and WHO. The campaign aimed at reaching the hardest-to-reach children previously missed by routine immunization services.
