Vaccine guidance for 15 travel regions, split into required for entry, recommended, worth considering for your itinerary, and prescription-only medication — with dose schedules and how far ahead of departure to start each one. Outbreak notices and destination recommendations follow the US CDC, whose travel-health database is one of the most detailed publicly available in English; if you're not travelling from the US, cross-check with your own country's health authority (UK's TravelHealthPro, Australia's Smartraveller, etc.) as guidance can differ slightly. Requirements and outbreak notices change, and what you personally need depends on your itinerary, season, and health history — confirm with a travel clinic before you book the appointment.
