American Samoa


American Samoa Required Vaccinations:
Routine Immunizations

Due to ongoing Measles outbreaks, American Samoa requires proof of Measles vaccination from travellers arriving from or in transit through Samoa or Tonga. Travellers between 6 months of age and those born in or after 1957 in the US and 1970 in Canada must show proof of vaccination. Travellers born before 1957 in the US and 1970 in Canada are considered immune. Vaccination must have been administered at least 14 days prior to arrival.

Travellers without proof of vaccination will be denied entry. Citizens and residents of American Samoa without proof of vaccination will be granted entry but will be quarantined for 14 days.

American Samoa citizens, residents, and US citizens departing American Samoa and travelling to areas with ongoing Measles outbreaks are recommended to get a Measles booster at least 14 days prior to travel.

Accepted proof of Measles vaccination includes: An immunization card that documents the type of vaccine, date of vaccination (minimum 14 days before travel), provider's name and signature, and the name and signature of person vaccinated. Documented laboratory confirmation of immunity or an immunization card documenting a history of measles disease will also be accepted. Nationals from Samoa or Tonga must provide proof of immunization from the Ministry of Health of Samoa or Tonga.

Your trip is a good occasion to make sure your routine immunizations are up-to-date. Many vaccine preventable illnesses are making a resurgence due to non-vaccination, incomplete vaccination, and waning immunity. See your healthcare practitioner if you are unsure of your vaccination status.
