Story highlights

Mosquirix (RTS,S), recommended by WHO for widespread use, is the first vaccine that is around 30% effective against severe cases of the mosquito-borne disease malaria and is given to children aged 6 weeks to 17 months. 

The RTS,S/AS01 malaria vaccine was recommended by the World Health Organisation on Wednesday, making it the first vaccination against the mosquito-borne illness that kills over 400,000 people each year, primarily African children.

The decision was taken after an assessment of a pilot programme that has been running in Ghana, Kenya, and Malawi since 2019 and has handed out over two million doses of the vaccine, which was initially developed by the pharmaceutical company GSK in 1987.

RTS, S/AS01 (trade name Mosquirix) is the first vaccination for children aged 6 weeks to 17 months that is about 30% effective against severe instances of the mosquito-borne illness malaria.

GlaxoSmithKline's four-dose vaccine, which took 30 years to develop, protects against Plasmodium falciparum, the deadliest malaria parasite found in Africa. 

It's also the first malaria vaccine to be offered by three national ministries of health through their childhood vaccination programmes; over 800,000 children in Ghana, Kenya, and Malawi have been immunised as part of a trial study, and are benefiting from the vaccine's additional protection.

Other recent clinical evidence suggests that timing the vaccine distribution just before the peak malaria transmission season in places where malaria is highly seasonal might maximise impact and significantly reduce mortality, especially when coupled with other malaria control measures. 

Malaria is a life-threatening parasitic illness spread by bites from infected female Anopheles mosquitoes.

It's both avoidable and treatable.

Despite this, there were a projected 229 million cases of malaria around the globe in 2019, with an estimated 409,000 malaria fatalities.

In 2019, children under the age of five are the most vulnerable to malaria, accounting for 67 percent (274,000) of all malaria fatalities worldwide.

According to WHO, India had an estimated 5.6 million cases of malaria in 2019, compared to nearly 20 million cases in 2000.
