GSK’s Mosquirix™ RTS,S/AS01e is a recombinant malaria vaccine with the P. falciparum circumsporozoite protein (CSP) from the pre-erythrocytic stage.

How does the Mosquirix vaccine work?

Mosquirix induces antibodies against malaria parasites that have entered the blood (via a mosquito bite) and have reached or are traveling to the liver, where they can mature and multiply. The vaccine thus limits the ability of the parasites to mature in the liver and cause clinical disease.

Why is the malaria vaccine ineffective?

The development of a malaria vaccine has faced several obstacles: the lack of a traditional market, few developers, and the technical complexity of developing any vaccine against a parasite. Malaria parasites have a complex life cycle, and there is poor understanding of the complex immune response to malaria infection.

Can you still get malaria after being vaccinated?

Unfortunately, such vaccines would not be useful for malaria eradication, because they do not eliminate infection in the human host, especially in areas of high transmission, and if transmission-blocking immunity is incomplete, mosquitoes can be infected.

What is the best vaccine for malaria?

Is efficacy the same as effectiveness?

Efficacy is the degree to which a vaccine prevents disease, and possibly also transmission, under ideal and controlled circumstances – comparing a vaccinated group with a placebo group. Effectiveness meanwhile refers to how well it performs in the real world.
