RTS,S malaria vaccine: what to know

RTS,S trains the immune system to recognise a protein linked to the malaria parasite. Protection is not the same as preventing every infection, and malaria risk varies with destination, season, accommodation, and activities. Vaccination decisions can also depend on age, health, previous travel, and local availability.

Malaria may cause fever, chills, headache, sweating, or muscle aches, but symptoms can appear after returning home. A blood test may be needed when malaria is suspected. Tell the clinician about recent travel and the areas visited.

Arrange a travel health consultation well before departure so there is time to review vaccination, malaria prophylaxis, mosquito avoidance, and your itinerary. Use repellent, wear clothing that covers exposed skin, and sleep behind intact screens or under a treated net where advised. Take prescribed preventive medicine exactly as directed and keep travel and medical details accessible.

Seek urgent medical assessment for fever or chills during travel or after returning from a malaria-risk area, especially if symptoms are accompanied by confusion, repeated vomiting, marked weakness, or breathing difficulty. Do not wait for symptoms to become severe or assume vaccination rules out malaria. Mention the travel history at the first contact.

Ask whether RTS,S is suitable for you, which preventive medicine matches your route, how to prevent mosquito bites, and what symptoms require testing after you return.
