Malaria Vaccines

A malaria vaccine is a vaccine that is used to prevent malaria. The only approved vaccine, as of 2021, is RTS,S, known by the brand name Mosquirix. In October 2021, the WHO for the first time recommended the large-scale use of a malaria vaccine for children living in areas with moderate-to-high malaria transmission. Four injections are required for full protection. Research continues with other malaria vaccines. The most effective malaria vaccine is R21/Matrix-M, with a 77% efficacy rate shown in initial trials and significantly higher antibody levels than with the RTS,S vaccine. It is the first vaccine that meets the World Health Organization's goal of a malaria vaccine with at least 75% efficacy.
