What Is the Combined Hep A and Typhoid Vaccine?
Many travellers focus on flights, visas, and accommodation when planning a trip abroad, but health risks are often overlooked. Infections such as hepatitis A and typhoid fever are still common in many parts of the world and are frequently linked to contaminated food and water. According to the World Health Organisation, typhoid fever affects an estimated 11 to 20 million people globally each year, while around 1.4 million hepatitis A infections occur annually. These numbers highlight why vaccination is often recommended before travelling to certain destinations.
The Hep A and typhoid vaccine offers protection against both infections through a single injection. By combining protection in one vaccination, it helps travellers prepare for destinations where exposure to these diseases may be more likely. Understanding how this vaccine works and who may benefit from it can help you make informed decisions before travelling.
What Is the Hep A and Typhoid Vaccine?
The Hep A and typhoid vaccine is a combined vaccine that protects against hepatitis A and typhoid fever. Both infections are typically spread through contaminated food or water, which is why they are often associated with international travel.
Instead of receiving two separate vaccinations, travellers can receive a single hep A and typhoid injection that offers protection against both diseases. This approach reduces the number of injections needed before travel and helps ensure that protection is provided in a timely way.
The typhoid and hep A vaccine is widely used in travel clinics across the UK and is recommended for people visiting areas where these infections are more common.
Why Do Travellers Need Protection Against Hepatitis A and Typhoid?
Both hepatitis A and typhoid fever are linked to hygiene conditions and sanitation. In many parts of the world these infections can spread through contaminated food, drinks, or poor hand hygiene.
Hepatitis A is a viral infection that affects the liver. It can cause symptoms such as fatigue, nausea, abdominal pain, and jaundice. Some people may recover within a few weeks, but the illness can still disrupt travel plans.
Typhoid fever is a bacterial infection caused by Salmonella typhi. It can lead to high fever, weakness, stomach pain, and digestive symptoms. Without treatment, it can become serious.
Because these infections are transmitted in similar ways, the combined injection for typhoid fever and hepatitis A is a practical option for travellers who need protection against both risks.
How Does the Combined Typhoid and Hep A Vaccine Work?
The hep A and typhoid vaccine works by helping your immune system recognise and fight the organisms that cause hepatitis A and typhoid fever.
After the vaccination, the body produces antibodies that can respond quickly if you are exposed to either infection during travel.
Protection against hepatitis A
The hepatitis A component of the vaccine contains an inactive form of the virus. This stimulates the immune system without causing the disease. Over time, the body develops immunity that helps prevent infection.
Protection against typhoid fever
The typhoid injection vaccine contains purified parts of the bacteria responsible for typhoid fever. These trigger an immune response that prepares the body to defend against the infection.
Convenience of a single injection
One of the main advantages of the typhoid and hep A vaccine is that it combines protection in a single appointment. This is particularly helpful for travellers preparing for trips at short notice.
Who Should Consider the Hep A and Typhoid Injection?
The hep A and typhoid injection is commonly recommended for people travelling to regions where sanitation and food safety standards may be different from those in the UK.
You may be advised to consider this vaccine if you are travelling to:
- Parts of Asia.
- Africa.
- Central or South America.
- The Middle East.
- Some areas of Eastern Europe.
Travellers who are staying with local families, visiting rural areas, or planning longer trips may have a higher risk of exposure to contaminated food or water.
Our pharmacists can assess your travel plans and advise whether the injection for typhoid fever and hepatitis A is suitable for you.
When Should You Get the Vaccine Before Travelling?
Ideally, the Hep A and typhoid vaccine should be given at least two weeks before travel. This allows the immune system enough time to build protection.
However, even if your travel date is approaching soon, vaccination may still offer some benefit. A travel consultation can help determine the best timing based on your destination and itinerary.
Some travellers may also require additional vaccines depending on where they are visiting. Travel health advice is tailored to each individual trip.
Are There Any Side Effects of the Typhoid Injection Vaccine?
Like most vaccines, the typhoid injection vaccine and hepatitis A vaccine may cause mild side effects. These usually settle within a short period.
Common side effects may include:
- Mild soreness or redness at the injection site.
- Headache.
- Fatigue.
- Slight fever.
Serious reactions are rare. During your consultation, our pharmacists will review your medical history and answer any questions you may have before administering the vaccine.
Where Can You Book the Hep A and Typhoid Vaccine?
If you are planning international travel, it is important to review vaccination requirements early. The Hep A and typhoid vaccine provides convenient protection against two infections that are commonly linked to contaminated food and water.

FAQs
How long does the Hep A and typhoid vaccine last?
The typhoid and hep A vaccine protects against both infections with one injection. Typhoid protection lasts about three years. A hepatitis A booster after 6 to 12 months provides longer-term protection.
How long before travel should I get the Hep A and typhoid injection?
It is recommended to get the hep A and typhoid injection at least two weeks before travel. This allows your immune system enough time to develop protection against both infections.
Can you get hepatitis A and typhoid vaccines together?
Yes, a combined Hep A and typhoid vaccine is available. It provides protection against both infections through a single injection, making travel vaccination simpler and more convenient for travellers.
Do I still need the vaccine if I am careful about food and water abroad?
Food and water precautions help reduce risk, but they cannot completely prevent infection. Vaccination provides additional protection, especially in destinations where sanitation standards or food safety may vary.
What diseases does the typhoid injection vaccine protect against?
The typhoid injection vaccine protects against typhoid fever caused by Salmonella typhi bacteria. When given as a combined vaccine, it also provides protection against hepatitis A.
Who should consider the injection for typhoid fever and hepatitis A?
Travellers visiting regions with a higher risk of food or water contamination may be advised to get the injection for typhoid fever and hepatitis A before travelling abroad.
