What is Malaria?
- Malaria is a disease caused by parasites that are transmitted to people through the bites of infected female Anopheles mosquitoes, called “malaria vectors.”
- Malaria is caused by Plasmodium parasites.
- It is preventable and curable.
About the malaria vaccine
- The only approved vaccine as of now is “RTS, S”, known by the brand name Mosquirix.
- The malaria vaccine prevents the parasite developing in humans.
- 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 in News?
- In a paper published in the New England Journal of Medicine, the efficacy of vaccination with or without chemoprevention (drugs) was studied and the combination of the interventions resulted in a substantially lower incidence of uncomplicated malaria.
