At TravelJabs4U, we often receive questions from travellers heading to Asia about the various vaccinations they need to stay safe during their trip. One of the most common queries is, “How long does the vaccine for hepatitis A last?”
In this blog post, we’ll answer this question in detail and provide useful information about hepatitis A and its prevention.
Q: What is Hepatitis A?
A: Hepatitis A is a viral infection that affects the liver. It is usually contracted by ingesting contaminated food or water. This makes it a particular concern for those travelling to regions with lower sanitation standards, such as parts of Asia, Africa, and South America. The virus can cause mild to severe illness. Symptoms include fatigue, fever, jaundice (yellowing of the skin and eyes), nausea, and abdominal discomfort. In some cases, hepatitis A can lead to liver failure, though this is rare.
Q: Why do I need a hepatitis A vaccine when travelling to Asia?
A: In many parts of Asia, including countries like India, Thailand, Vietnam, and Cambodia, the sanitation infrastructure may not meet the same standards as in the UK. As a result, food and water can become contaminated with the hepatitis A virus. While careful selection of what and where you eat and drink can help minimise risk, vaccination provides a reliable defence against infection.
Even if you’re staying in high-end resorts or restaurants, exposure is still possible, as the virus can spread even in settings that appear clean and safe.
Q: How long does the vaccine for hepatitis A last?
A: The vaccine for hepatitis A provides long-lasting protection. After receiving the initial dose, you will have protection for approximately 12 months. However, to ensure long-term immunity, it’s recommended to have a booster dose 6 to 12 months after the first injection. Once you’ve had the booster, your immunity to hepatitis A can last for up to 25 years, and possibly even longer.
Q: What happens if I only receive one dose of the vaccine?
A: If you only receive the initial dose of the hepatitis A vaccine, you’ll still be protected for up to 12 months, which is sufficient for most short-term trips. However, to maintain long-term protection, it’s important to follow up with the booster dose after 6 to 12 months. Without the booster, your protection will wane over time. As a result, you’ll need to consider revaccination if you plan to travel again in the future.
At TravelJabs4U, we always encourage our patients to complete the full course of the hepatitis A vaccine, particularly if they are frequent travellers or planning to return to regions where the disease is prevalent.
Q: Can I combine the hepatitis A vaccine with other vaccines?
A: Yes, the hepatitis A vaccine can be given alongside other vaccines, such as those for hepatitis B, typhoid, or cholera. For example, the combined hepatitis A and B vaccine provides protection against both diseases with a convenient schedule of three doses over six months.
If you’re planning a trip to Asia, particularly to areas where hepatitis A, B, or other diseases are a concern, we recommend discussing your travel plans with us at TravelJabs4U. We can then tailor a vaccination plan that suits your specific itinerary.
Q: What other vaccines do I need when travelling to Asia?
A: When travelling to Asia, it’s essential to consider additional vaccines beyond hepatitis A to protect yourself from potential health risks. Depending on your destination and activities, other vaccines may be recommended to safeguard you during your trip. Here’s a list of key vaccines commonly advised for travel to Asia:
- Hepatitis B
- Typhoid
- Japanese Encephalitis
- Rabies
- Cholera
- Tetanus
- Tuberculosis
- Yellow Fever (if travelling from or through an affected area)
Be sure to consult a travel health professional to determine the best vaccinations for your specific travel plans.
Q: Where in Asia is the hepatitis A vaccine recommended?
A: The hepatitis A vaccine is recommended for travel to most parts of Asia. This includes popular tourist destinations like Thailand, India, Cambodia, Vietnam, Indonesia, and the Philippines. It’s particularly crucial if you plan to visit rural areas or regions with less developed infrastructure. Even in cities, the risk of exposure can still exist, so it’s better to be safe than sorry.
We assess each traveller’s itinerary and individual risk factors to provide the best advice.
Q: Can the hepatitis A vaccine be given in a single visit?
A: Yes, the initial dose of the hepatitis A vaccine can be given in a single visit. You will then be protected for 12 months. If you’re planning to travel again in the future, we’ll remind you to return for the booster dose. This will extend your protection for decades.
For those in a hurry, we also offer combination vaccines, such as the combined hepatitis A and typhoid vaccine. This can save you time and protect against two common travel-related illnesses.
Long-term Protection
Hepatitis A is a significant health risk in many parts of Asia, and vaccination is the most effective way to protect yourself. If you’re asking, “How long does the vaccine for hepatitis A last?” the answer is simple: with the full two-dose course, you can enjoy long-term protection of up to 25 years or more.
