RTS,S/AS01 (trade name Mosquirix) is a recombinant protein-based malaria vaccine. It is one of two malaria vaccines approved (the other is R21/Matrix-M). As of April 2022, the vaccine has been given to 1 million children living in areas with moderate-to-high malaria transmission, with millions more doses to be provided as the vaccine's production expands. 18 million doses have been allocated for 2023-2025. It requires at least three doses in infants by age 2, with a fourth dose extending the protection for another 1–2 years. The vaccine reduces hospital admissions from severe malaria by around 30% and reduces toddler deaths by 15%.
