What should you know about malaria vaccine?

Malaria is an infection spread through bites from infected mosquitoes. Vaccination is one layer of prevention; it does not replace advice about the destination, bite avoidance, or medicines that may be recommended for prevention. Protection depends on the vaccine used, the person receiving it, and the exposure risk. A clinician can explain whether vaccination is relevant to your itinerary and health history.

Fever, chills, and muscle aches after travel to a malaria-risk area deserve prompt medical attention, even if you received a vaccine or took preventive medicine. Symptoms can begin after you return, so tell the clinician where you travelled and when.

Arrange a travel health consultation before departure. Take your itinerary, dates, current medicines, allergies, pregnancy plans, and information about long-term health conditions. Ask which vaccine schedule, if any, applies to you, and whether malaria prophylaxis is advised.

Use repellent as directed, wear clothing that covers exposed skin, and sleep behind intact screens or under suitable bed nets. Follow the agreed schedule for any preventive medicine. Keep a record of vaccination and travel advice so it is available during the trip and after you return.

Seek urgent medical assessment for fever during or after travel in a malaria-risk area, particularly when it occurs with chills, marked weakness, confusion, breathing difficulty, repeated vomiting, or fainting. Do not wait for symptoms to settle because malaria can worsen quickly.

A blood test may be used when malaria is suspected. Tell the healthcare team about recent travel, mosquito exposure, vaccination, and preventive medicines; these details help guide testing and treatment.

Ask: Is this vaccine suitable for my destination and health history? When should each dose be given? Do I also need malaria prophylaxis? Which symptoms should prompt care while travelling, and where can I obtain a blood test after returning?
