About

About the Vaccine

  • The WHO recommendation is for RTS, S - or Mosquirix- a vaccine developed by British drug maker GlaxoSmithKline.
  • The active ingredient in Mosquirix is made up of proteins found on the surface of Plasmodium falciparum parasites (PFP).
  • RTS, S aims to start the immune system in the early stages of malaria when PFP enters the bloodstream through a mosquito bite and infects liver cells.
  • The RTS malaria vaccine, S / AS01 is used to prevent falciparum malariain children living in regions with moderate to high transmission.
    • Falciparum, the most common form of malaria in Africa.
  • It is the first vaccine and the only one that shows partial protection against young children.
  • The malaria vaccine should be given in a 4-dose program to children from five months of age to reduce the incidence of malaria and the burden.
  • The vaccine adds to the development of the malaria tool and can help get malaria control back on track.
  • It also helps prevent liver infection with the Hepatitis B virus.
