RTS,S

RTS,S is a malaria vaccine. It is the world's first licensed malaria vaccine and also the first vaccine licensed for use against a human parasitic disease of any kind.
Its efficacy ranges from 26 to 50% in infants and young children.
In October 2021, the vaccine was supported by the World Health Organization for large use in children, making it the first malaria vaccine candidate, and first vaccine to fight against the parasitic infection, to receive this recommendation.
