Promoting Healthier International Travel


Many travelers head overseas without the protection of effective vaccines or medications to prevent common, debilitating, and life-threatening diseases such as malaria and viral hepatitis. The San Francisco Department of Public Health encourages international travelers to visit a travel medicine specialist prior to departure. 

If your health system does not offer a travel medicine specialist, or if you would like to visit our non-profit clinic staffed by experienced travel health clinicians, the AITC Immunization & Travel Clinic is open to the public.
