Types of malaria vaccines: what to know

Available malaria vaccines target the parasite during an early part of its journey in the body. They are designed mainly for children living in areas where malaria transmission is common, under local vaccination programmes. Suitability, schedule and availability depend on age, destination, health history and public-health guidance. A vaccine cannot cover every parasite stage or every travel situation, so a vaccinated person can still develop malaria. Fever, chills and muscle aches after exposure require medical attention rather than reassurance from vaccination status.

For travel, arrange a travel health consultation early enough to discuss destination-specific risk, mosquito-bite prevention and malaria prophylaxis. Use insect repellent, wear clothing that limits exposed skin and sleep in a protected room or under a suitable net where advised. Take prescribed prophylaxis exactly as directed; the choice can depend on destination and medical history. Keep a record of vaccines and medicines, and tell a clinician about travel if illness develops later.

Get prompt medical advice for fever or chills during travel or after returning from a malaria area, even when vaccinated or taking prophylaxis. Seek emergency help for confusion, collapse, breathing difficulty, seizures or severe drowsiness. A blood test may be needed because malaria cannot be ruled out from vaccination history alone.

Ask whether vaccination is relevant to your age or travel plan, which other prevention measures are needed, what schedule applies, and what symptoms should trigger testing after you return.
