Last month, the United Nations said its “big catch-up” child vaccination campaign was on track to hit its 21 million children target. The Covid-19 pandemic disrupted its vaccination campaigns. This resulted in a resurgence of infectious diseases.
It was a three-year effort to immunise children who had missed routine jabs.
The UN’s World Health Organization and its children’s agency, Unicef, made a joint statement with Gavi, the Vaccine Alliance.
The campaign reached an estimated 18.3 million children by December 2025. More than 100 million doses of life-saving vaccines were given. Of the children reached, around 12.3 million had never received a vaccine dose before. At least 15 million had never received a measles vaccine.
The vaccine drive concluded in March. The final data is still being collected.
