Malaria vaccines are vaccines that prevent malaria, a mosquito-borne infectious disease which affected an estimated 249 million people globally in 85 malaria-endemic countries and areas and caused 608,000 deaths in 2022.[2] The first approved vaccine for malaria is RTS,S, known by the brand name Mosquirix.[1] As of April 2023, the vaccine has been given to 1.5 million children living in areas with moderate-to-high malaria transmission.[3] It requires at least three doses in infants by age 2, and a fourth dose extends the protection for another 1–2 years.[4][5] The vaccine reduces hospital admissions from severe malaria by around 30%.[4]
Research continues with other malaria vaccines. The most effective malaria vaccine is the 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 (WHO) goal of a malaria vaccine with at least 75% efficacy,[6][7] and only the second malaria vaccine to be recommended by the WHO.[8] In April 2023, Ghana's Food and Drugs Authority approved the use of the R21 vaccine for use in children aged between five months and three years old.[9] Following Ghana's decision, Nigeria provisionally approved the R21 vaccine.[10]
