Planning a trip to China, India, or another popular Asian destination? One important precaution you should take is getting the hepatitis B vaccine. Hepatitis B is a serious viral infection that affects the liver and can lead to long-term health problems if left untreated. For travellers, especially those visiting countries where the virus is more prevalent, vaccination offers essential protection.
In this guide, we’ll explore why the hepatitis B vaccine should be part of your travel health plan, what hepatitis B is, how it’s transmitted, and who is most at risk when travelling.
What is Hepatitis B?
Hepatitis B is a viral infection that attacks the liver, causing inflammation and potentially leading to serious complications like liver cirrhosis, liver failure, or liver cancer. It is one of the most widespread infectious diseases in the world, with a higher prevalence in parts of Asia. Travellers heading to Africa and the Pacific Islands should also consider vaccination.
The virus is spread through contact with infected blood or bodily fluids, such as during unprotected sex, the sharing of needles, or even exposure to contaminated medical equipment. While many people infected with hepatitis B may not show symptoms, chronic infection can persist for years and cause serious liver damage over time.
Why Should Travellers Consider the Hepatitis B Vaccine?
Travelling exposes you to a range of health risks, and while your destination may have fascinating attractions, it can also pose potential dangers in terms of infectious diseases. China, India, and other Asian destinations have higher rates of hepatitis B transmission than many Western countries, which is why the hepatitis B vaccine is strongly recommended for travellers.
Here’s why getting the hepatitis B vaccine before you travel is a smart choice:
High Prevalence: In many parts of Asia, Africa and the Pacific Islands, the hepatitis B virus is endemic, meaning it’s consistently present in the population. The World Health Organization (WHO) estimates that around 5% of the world’s population is infected with chronic hepatitis B. Travellers can unknowingly come into contact with the virus through medical and aesthetic procedures, having unprotected sex, or even minor accidents.
Risk of Exposure: While hepatitis B is often associated with risky behaviours such as sharing needles or having unprotected sex, the virus can also be transmitted through less obvious means. For example, if you need medical treatment while abroad, the standard of healthcare may not always meet UK levels, and there is a risk of exposure to contaminated equipment. In certain settings, even tattooing or acupuncture could pose a risk if hygiene standards are not met.
Long-Term Health Risks: Unlike hepatitis A, which typically resolves on its own, hepatitis B can lead to chronic infection. If you contract hepatitis B and develop a chronic infection, you may face long-term liver problems, including cirrhosis or liver cancer. Protecting yourself with the hepatitis B vaccine greatly reduces your risk of contracting the virus during your travels.
Who Should Get the Hepatitis B Vaccine?
The hepatitis B vaccine is recommended for a wide range of travellers, particularly those heading to countries where the virus is more common. At HMI Pharmacy, we advise that travellers should consider vaccination if:
- – You are travelling for extended periods or staying with local families.
- – You plan to engage in activities that could increase your risk, such as working in healthcare, volunteering in medical or humanitarian settings, or undergoing medical treatment.
- – You are likely to have close personal contact with local populations, especially in rural or less developed areas.
- – You are considering getting tattoos, piercings, or other procedures while abroad.
Even if you don’t fall into a high-risk group, it’s important to recognise that accidents happen. Travellers can face unexpected injuries or medical needs while abroad, and receiving treatment in a country with higher hepatitis B prevalence can put you at risk if proper sterilisation protocols are not followed.
How Does the Hepatitis B Vaccine Work?
The hepatitis B vaccine works by stimulating your immune system to produce antibodies that protect against the hepatitis B virus. The vaccine is highly effective and is usually administered as a series of three injections over six months. The typical schedule is:
- 1. The first dose is given at any time
- 2. The second dose is administered one month after the first
- 3. The third dose is given six months after the first
For those who are short on time before their travels, an accelerated vaccination schedule is also available. This involves receiving the three doses over a shorter period, followed by a booster after 12 months.
At HMI Pharmacy, we can help you plan the best vaccination schedule depending on your travel dates. It’s important to get your vaccinations well in advance to ensure full protection before your trip.
Additional Precautions to Take
While getting the hepatitis B vaccine is a critical step in protecting your health, there are additional precautions you can take to avoid hepatitis B and other travel-related illnesses:
Practise safe sex: Use condoms if you engage in sexual activity with new partners.
Avoid risky medical procedures: Seek medical care only in reputable healthcare facilities that follow proper hygiene protocols. If you need dental work or surgery, ensure that the instruments are sterilised.
Don’t share needles or personal items: Avoid sharing needles, razors, or any other items that could come into contact with blood.
Be cautious with tattoos and piercings: Only get tattoos, piercings, or acupuncture in reputable establishments that use sterilised equipment.
