Vaccine Info

Mosquirix (RTS,S)

Mosquirix is a vaccine that is given to children aged 6 weeks to 17 months to help protect against malaria caused by the parasite Plasmodium falciparum.

The vaccine should only be used in areas of the world where malaria caused by Plasmodium falciparum is prevalent, and according to official recommendations in those areas.

Mosquirix also helps protect against infection of the liver with the hepatitis B virus but should not be used only for this purpose.

Mosquirix  RTS,S [Portion of P. falciparum circumsporozoite protein fused with hepatitis B surface antigen (RTS), and combined with hepatitis B surface antigen (S)]

Mosquirix does not provide complete protection against malaria caused by P. falciparum.

RTS,S aims to trigger the immune system to defend against the first stages when the Plasmodium falciparum malaria parasite enters the human host’s bloodstream through a mosquito bite and infects liver cells. The vaccine is designed to prevent the parasite from infecting the liver, where it can mature, multiply, re-enter the bloodstream, and infect red blood cells, which can lead to disease symptoms.
