About WhichVax

What is WhichVax?

WhichVax is a free travel health information tool covering 200+ destinations worldwide. It helps travellers quickly understand which vaccines are required or recommended for their destination, how much they might cost, and when to book their clinic appointment.

Where does the data come from?

All vaccine recommendations are based on guidelines published by the World Health Organization (WHO) and the US Centers for Disease Control and Prevention (CDC). Data is reviewed and updated regularly. Last updated: April 2026.

Is this medical advice?

No. WhichVax provides general information only — it is not a medical service and does not provide personalised medical advice. Always consult a qualified travel health professional or your GP before travelling. Requirements and risks change, so always verify with an official source close to your departure date.
