As more people travel to countries where food and water contamination is common, the risk of catching salmonella typhi increases. Typhoid fever is a serious illness that can disrupt travel plans and lead to long term health problems if not treated promptly. At Vivo Pharmacy, we help travellers stay protected with expert advice and private vaccinations at our travel clinic in Bristol. Below, we answer the most common questions about how effective the typhoid vaccine is and how boosters help maintain protection. If you need guidance for an upcoming trip, you can contact us or book your vaccination appointment today.
What Is Salmonella Typhi?
Salmonella typhi is a bacterium that causes typhoid fever, an infection spread through contaminated food, drink or poor hygiene conditions. Travellers visiting parts of Asia, Africa, South America and Central America are most at risk. If you are unsure whether your destination carries a higher risk, reach out to our team at Vivo Pharmacy for tailored travel health advice.
How Effective Is the Typhoid Vaccine?
There are two main types of typhoid vaccines available in the UK. Both offer strong protection against salmonella typhi, although no vaccine provides 100 percent immunity.
The injectable typhoid vaccine provides around 72 percent protection.
The oral typhoid vaccine provides around 70 percent protection.
These protection levels significantly reduce the risk of infection, especially when combined with sensible food and water safety measures. If you want the right protection for your trip, visit us at our travel clinic in Bristol for a full consultation.

Does the Typhoid Vaccine Protect Against All Strains?
The vaccine protects against the most common strains of salmonella typhi, which cause the vast majority of typhoid fever cases worldwide. However, it does not protect against other types of salmonella that cause food poisoning. This is why combining vaccination with good hygiene and food safety habits remains essential. If you need advice on safe travel practices, contact us for personalised guidance.
How Long Does Typhoid Vaccine Protection Last?
Protection from the injectable vaccine lasts for around three years.
Protection from the oral vaccine lasts for around five years.
After this time, your immunity begins to weaken. If you travel frequently or are returning to a high risk destination, you may need a booster dose. You can book your booster appointment with our travel clinic in Bristol to ensure you stay fully protected.
When Should I Get My Typhoid Vaccine Before Travelling?
You should ideally receive the typhoid vaccine at least two to three weeks before you travel. This gives your body enough time to develop strong immunity. However, if you are travelling sooner, we can still help. Vivo Pharmacy offers short notice appointments and fast access to vaccination.

Do I Need a Booster for Future Trips?
Yes. Boosters are recommended if you are travelling again after your protection period has expired. The injectable vaccine requires a booster every three years, while the oral vaccine requires one every five years. Regular travellers, backpackers and long stay visitors are more likely to need timely boosters. You can book your booster at our travel clinic in Bristol for ongoing protection.
Is the Typhoid Vaccine Safe?
The typhoid vaccine is considered very safe, with most people experiencing little to no side effects. Any symptoms that do appear are usually mild and temporary, such as:
• Slight soreness at the injection site
• Low grade fever
• Headache
• Mild digestive symptoms with the oral vaccine
If you have medical conditions or allergies and are unsure about suitability, contact us for expert advice. Our clinicians always assess your health before vaccination to ensure your safety.
Can I Take Typhoid and Other Travel Vaccines Together?
Yes. Many travellers require multiple vaccines before heading abroad, such as hepatitis A, hepatitis B or tetanus boosters. Typhoid vaccination can safely be given alongside other vaccines. During your consultation, our travel clinic in Bristol will review your itinerary and tailor a full vaccination plan for you. Reach out to us if you would like support arranging all your travel health needs in one visit.

If I Have Had Typhoid Before, Do I Still Need the Vaccine?
Past infection does not guarantee lifelong immunity. Many people who have previously had typhoid can still become reinfected. Vaccination offers renewed and dependable protection. If you are unsure about your immunity, contact us, and we can advise you on the best approach.
Do Children Need the Typhoid Vaccine?
Children over two years old can receive the injectable typhoid vaccine. Families travelling together should plan ahead, as children often face the same exposure risks as adults. If you are travelling with young children, visit us for tailored guidance.
Protect Yourself Before You Travel
The typhoid vaccine is one of the most important travel vaccines for people visiting high risk regions. While it does not prevent every case, it provides strong and essential protection against salmonella typhi when combined with safe food and water habits.
