An international team have used cutting edge genomic methods to uncover key biological insights that help explain the protective effects of the world's most advanced malaria vaccine candidate, RTS,S/AS01 (RTS,S).
RTS,S is the first malaria vaccine candidate to complete phase 3 trials. Originally designed by scientists at GlaxoSmithKline (GSK) in 1987, development of the vaccine is now being advanced by a public-private partnership between GSK and PATH Malaria Vaccine Initiative.
Applying highly sensitive sequencing technology to more patient samples than previously tested, the team was able to determine that genetic variation in the protein targeted by RTS,S influences the vaccine's ability to ward off malaria in young children.
