What to know about the first malaria vaccine

Malaria vaccines train the immune system to recognise part of the parasite. Eligibility, product choice and the recommended schedule depend on age, destination, health circumstances and local programme guidance. Protection is not complete, so a vaccinated person can still develop malaria. Fever, chills or muscle aches after travel should be assessed promptly; symptoms cannot be safely dismissed because someone received a vaccine. The vaccine also does not protect against every mosquito-borne illness.

Book a travel health consultation well before visiting a malaria area. Discuss the destination, length and style of travel, pregnancy or plans for pregnancy, allergies and regular medicines. The clinician can explain whether vaccination is suitable and whether malaria prophylaxis is advised. Use insect repellent, cover exposed skin, sleep under suitable netting and reduce mosquito exposure during peak biting times. Carry your vaccination and travel-health information.

Seek urgent medical assessment for fever during travel or after returning from a malaria area, particularly with confusion, fainting, severe weakness, breathing difficulty, repeated vomiting or inability to drink. Tell the clinician where you travelled and that you received a malaria vaccine. A blood test may be needed even when vaccination and other precautions were used.

Ask whether the vaccine is appropriate for your destination and health, how the schedule works, which side effects need attention, whether prophylaxis is also advised, and what to do if fever develops after travel.
