Chelsea Green Pharmacy
At Chelsea Green Pharmacy, we’re committed to helping you prepare for your travels safely and effectively. If you’re heading to regions where typhoid fever is prevalent, ensuring you’re protected against this serious illness is essential. One of the most common questions we’re asked is: “When should I get the typhoid vaccine, and how long does it last?” In this guide, we’ll explain the best timing for your vaccination, how long the vaccine provides protection, and whether boosters are necessary for long-term travellers.
Why Is the Typhoid Vaccine Important for Travellers?
Typhoid fever is caused by the bacterium Salmonella Typhi and is typically spread through contaminated food or water. It is most common in areas with poor sanitation, such as parts of South Asia, Southeast Asia, Africa, and Central and South America. Symptoms include high fever, abdominal pain, vomiting and diarrhoea, constipation, and weakness. If left untreated, it can lead to severe complications, including intestinal perforation.
The typhoid vaccine significantly reduces your risk of contracting the disease. While it’s not 100% effective, it offers critical protection, particularly when combined with safe food and water practices during your travels.
When Should You Get the Typhoid Vaccine Before Travelling?
It’s recommended to get the typhoid vaccine at least two weeks before your departure date. This allows enough time for your body to develop immunity against the bacteria. While some protection may begin within a few days of receiving the vaccine, the two-week window ensures maximum effectiveness.
If you’re planning a last-minute trip, you can still receive the vaccine closer to your departure date, but earlier is always better. At Chelsea Green Pharmacy, we offer convenient appointment options to fit your travel schedule.
Typhoid Vaccine: How Long Does It Last?
The duration of protection depends on the type of vaccine you receive:
Injectable Typhoid Vaccine (Typhoid Vi Polysaccharide Vaccine): This single-dose injection provides protection for up to three years. If you’re at continued risk of exposure, you’ll need a booster shot every three years to maintain immunity.
Oral Typhoid Vaccine (Ty21a): This vaccine involves taking four capsules over seven days. It provides protection for up to five years but requires careful adherence to the schedule for full effectiveness. A booster course is recommended every five years if you remain at risk.
Both vaccines are safe and effective, and our pharmacists can help you decide which option is best for your travel plans and personal preferences.
Do Long-Term Travellers or Ex-Pats Need a Booster Vaccine?
If you’re planning an extended stay in a high-risk area or relocating abroad as an ex-pat, you’ll likely need a booster vaccine to maintain protection against typhoid fever. Here’s what you need to know:
Short-Term Travel (Less Than Three Years): A single injectable typhoid vaccine dose will provide sufficient protection for up to three years. For those opting for the oral vaccine, immunity will last up to five years.
Long-Term Travel (More Than Three Years): For stays exceeding the vaccine’s duration of immunity, boosters are essential. Injectable vaccines require a booster every three years, while oral vaccines need a booster every five years.
At Chelsea Green Pharmacy, we recommend booking a consultation to plan your vaccination schedule if you’ll be living or travelling long-term in an area where typhoid is common.
Is the Typhoid Vaccine Different for Children, Adults, and the Elderly?
The typhoid vaccine is suitable for most age groups, but there are some differences to consider:
Children
The injectable typhoid vaccine is licensed for children as young as two years old, while the oral vaccine is suitable for children aged six and above. Children may require more careful monitoring for side effects, such as mild fever or soreness at the injection site.
Adults
Both the injectable and oral vaccines are effective for adults. Depending on your travel plans and medical history, our pharmacists can advise which option is best for you.
Elderly
The vaccine is safe for older travellers, but some elderly individuals may have a less robust immune response, particularly if they have underlying health conditions. In these cases, boosters or additional precautions may be necessary to ensure adequate protection.
Our pharmacists at Chelsea Green Pharmacy will provide tailored advice for travellers of all ages, ensuring everyone in your group is fully prepared.
Additional Tips for Typhoid Prevention
While the typhoid vaccine is an important safeguard, it’s not 100% effective. To further reduce your risk of infection:
- Drink bottled or boiled water and avoid ice in drinks.
- Eat food that is freshly cooked and served hot.
- Avoid raw or undercooked foods, particularly shellfish and street food.
- Wash your hands frequently with soap and water or use hand sanitiser.
