Cameroon Malaria Vaccine Cuts Severe Illness but Fourth Dose Lags
Health workers say the vaccine is reducing severe illness, but only 25% of children received the fourth dose in 2025, officials said.
Health workers in Cameroon and other African nations struggle to ensure children receive the critical fourth booster malaria dose, with coverage dropping to 25% in 2025.
Although parents show "huge demand" for the vaccine, many miss later doses due to transportation costs, lack of reminders, and competing work responsibilities. Gavi Chief Executive Officer Dr. Sania Nishtar called these "initial teething problems" that shouldn't diminish the vaccine's value.
For families where nearly 40% of the population lives in poverty, preventing malaria means avoiding crushing medical bills. Mothers report spending between $53 and $107 per illness.
Dr. Bomba Amougou, head of prevention at the National Malaria Control Program, emphasized that receiving all four doses "makes the protection more potent." He added vaccination must complement bed nets and prompt treatment.
Cameroon and other nations launched "Big Catch-up" campaigns to prioritize child vaccinations while researchers pursue a single-dose vaccine. Nishtar noted that reducing required doses would significantly increase uptake and simplify administration.
