TL;DR:Keep routine shots current; essential additional vaccines for expats are hepatitis A and B, typhoid (if rural), Japanese encephalitis (rural/long stay), and rabies if exposed to animals; yellow fever only if arriving from risk countries.
Expats must be up to date with routine immunisations (MMR, Tdap, polio, influenza) and should get travel‑specific vaccines based on duration, location and planned activities. Core recommendations for living in Thailand: hepatitis A (recommended for all), hepatitis B (recommended for most), typhoid (if you’ll eat outside major cities), Japanese encephalitis (for long stays or rural/northern exposure), and rabies (if you expect animal contact or long rural stays). Yellow fever vaccine is required only for arrivals from countries with yellow fever risk. No routine entry vaccine is required otherwise, but ensure COVID-19 vaccinations follow current national guidance. Consult a travel clinic before departure for personalised advice and catch‑up schedules; post‑exposure rabies treatment and other vaccines are available in Thailand.
