Recommended Vaccinations for Rarotonga and the Cook Islands

Despite the list of recommended vaccinations, the likelihood of visitors to the Cook Islands getting an infectious disease is very slim, except for dengue fever (see in the “Health Issues to Be Aware of in the Cook Islands” section below), which there is no vaccine for.

Nevertheless, it’s always a good idea to make sure your routine vaccinations are up-to-date (adults require boosters for some vaccines), and get the travel vaccinations that we list below to stay on the safe side.

Visit your travel clinic or GP 4-6 weeks before your trip to get up-to-date information on which vaccines are best to have for the Cook Islands. When you get vaccines for you or your children, make sure to keep a record of them – many practices offer a “Travel Vaccination Passport”.

Travel Vaccinations for the Cook Islands

Hepatitis A Vaccine

Hepatitis A spreads through food and water. While most people recover completely from hepatitis A, the vaccine is close to 100% protective.

Hepatitis B Vaccine

Hepatitis B spreads through blood and body fluids and is much more serious than hepatitis A. While treatment is complex, the prevention vaccine is highly effective.

Typhoid Vaccine

Typhoid is a disease spread through food and water. There is no recent history of typhoid outbreaks in the Cook Islands. The typhoid vaccine typically lasts two years.

COVID-19 Vaccine

Although most of the population in Samoa is vaccinated against COVID-19, it can still be prevalent in travellers to and from the country. It’s best to be vaccinated to avoid/decrease symptoms.

Measles Mumps Rubella (MMR) Vaccine

The MMR vaccine is given to children as routine in many countries. The vaccine is recommended to anyone unvaccinated. An adult booster is also recommended.

These airborne diseases are also spread through wounds. While this is a routine vaccination in children in many countries, an adult booster is recommended, particularly for pertussis.

Polio spreads through food and water. The polio vaccine is considered routine for children in many countries. A single adult booster vaccine is recommended.
