Hepatitis A
A contagious liver infection spread through contaminated food and water. Most travellers to regions with less reliable sanitation should get this vaccine.
Dosing & timing
Two doses at 0 and 6–12 months. Over 90% of people develop protective antibodies within a month of the first dose, so one dose is usually enough for the trip itself. No booster needed after the full series.
