Malaria Vaccine: Helping Parents and Caregivers Make Informed Decisions

What is the Malaria Vaccine?

The malaria vaccine protects against malaria, a life-threatening illness caused by the Plasmodium parasite, which is transmitted through the bite of an infected female Anopheles mosquito. Plasmodium falciparum is the most common species of the parasite. Children are at high risk of malaria illness and death, particularly in regions with moderate to high malaria transmission.

How the Vaccine Works

The RTS,S/AS01 malaria vaccine is the first and currently the only malaria vaccine recommended for use by the World Health Organization (WHO). It is a pre-erythrocytic recombinant protein vaccine based on the RTS,S recombinant antigen. The vaccine works by stimulating the immune system to produce antibodies against the Plasmodium parasite, providing protection against malaria.

Vaccine Characteristics, Content, Dosage, Administration, and Storage

Vaccine Characteristics

The RTS,S/AS01 malaria vaccine is a pre-erythrocytic recombinant protein vaccine based on the RTS,S recombinant antigen. The RTS,S antigen is lyophilized and needs to be reconstituted with the liquid AS01 adjuvant system prior to administration.

Dosage and Administration

Dosage: The vaccine is currently produced as a 2-dose RTS,S powder to be reconstituted with a 2-dose AS01 adjuvant system suspension. After reconstitution, the total volume is 1 ml (2 doses of 0.5 ml).
Administration: The reconstituted vaccine should be administered by injection into the left deltoid muscle in children at 6, 7, 9, and 24 months of age.

Storage

Storage Temperature: The vaccine should be stored at 2–8 °C.
Shelf Life: The shelf life of the RTS,S/AS01 vaccine is 3 years.
Vaccine Vial Monitor: A vaccine vial monitor is on the AS01 vial.

Contraindications

The only contraindication to the use of the RTS,S/AS01 vaccine is severe hypersensitivity to any of the vaccine components.

Co-administration

The vaccine can be co-administered with other routine vaccines.

Vaccine Safety

The RTS,S/AS01 vaccine is safe and well-tolerated. There is a small risk of febrile seizures within 7 days (mainly within 2–3 days) of vaccination.

Vaccination of Special Populations

Malnourished or HIV-positive infants should be vaccinated with the RTS,S/AS01 vaccine using a standard schedule. These children are at particular risk from malaria infection, and the vaccine has been shown to be safe in these groups.
