Travel Vaccinations Necessary for a Trip to Tonga

Tonga is considered one of the best destinations for a holiday in the South Pacific at any time of the year, and it's also a great place to go for a rugby world cup event. But before you head off to the paradise that is Tonga and get ready for some fun in the sun and beneath the waves, check out the travel vaccinations below.

These are the vaccinations that will be necessary to ensure your health during your stay in Tonga, so be sure to book an appointment with your GP or visit a place like the London Travel Clinic and let them know that you need the necessary vaccinations for holidays in Tonga.

Hepatitis A

All visitors who go to Tonga are required to get a single dose vaccination for Hepatitis A. This disease is basically a very serious liver infection that's caused by a virus, and it's very contagious.

The Hepatitis A virus, also referred to as HAV for short, is transmitted typically via a faecal-oral route, so it can be transmitted from one person to the next or by eating and drinking contaminated food and water.

The good news is that HAV does not result in chronic illness and it's a self-limited disease. Over 80 per cent of the adults who are infected will end up having symptoms, which include nausea, vomiting, low-grade fever, fatigue, joint pain, and jaundice, to name a few.

Hepatitis B

A 3-course vaccination for Hepatitis B is also required for a trip to Tonga. This vaccination will protect you from HBV—the Hepatitis B virus—which is another serious liver infection. This infection, however, can become chronic, increasing the risk of liver cancer, cirrhosis, and liver failure. Once infected, there's no cure and you can spread it to others.

Symptoms of infection include dark urine, abdominal pain, jaundice, joint pain, fever, loss of appetite, nausea, vomiting, fatigue, and weakness.


A standard rabies vaccine is a 3-course regimen, but if you're bitten by an animal that's suspected of having rabies, you'll need to get additional rabies shots to ensure protection against infection.

Because certain parts of the world have animals that could potentially be carrying this deadly disease for which there is no cure, you should be properly vaccinated before you leave home, just in case you're bitten.

Tetanus, Diphtheria and Polio

The combination vaccine for Tetanus, Diphtheria and Polio is a single dose shot that will protect you against these three diseases.

Diphtheria is a bacterial illness that results in difficulty breathing and can lead to heart failure, a build-up of nervous system toxins, and respiratory failure.

Tetanus is also a bacterial infection that can be introduced into your body via a wound. It results in muscle spasms and is potentially fatal.

Polio, which is also potentially fatal, is a viral infection that's very contagious and could result in permanent paralysis and nerve damage of respiratory muscles and limbs.

By taking the steps to make sure you get all of the necessary travel vaccinations before heading off to Tonga, you can rest assured that your health will be protected while you're away from home.
