Typhoid Vaccine

What is Typhoid Fever?

Typhoid fever is a serious bacterial infection that can have severe consequences if left untreated. It spreads throughout the body, affecting multiple organs and can even lead to complications such as internal bleeding, which can be fatal. It is primarily prevalent in areas where hygiene standards are low, such as the Indian subcontinent, parts of Africa, south and southeast Asia, and South America.

Typhoid Fever Vaccines

There are two types of typhoid vaccines available: the Vi vaccine and the Ty21a vaccine. The Vi vaccine is administered in a single dose as a single injection, while the Ty21a vaccine is given in three doses as capsules taken on alternate days. The choice of vaccine depends on factors such as your age and medical history, which will be determined by our experienced healthcare professionals.

How effective is the Typhoid Vaccine?

It’s important to note that while the typhoid vaccine is highly effective, it is not 100% foolproof. Therefore, even after vaccination, it is crucial to take extra precautions while consuming food and water abroad. By practising caution and following recommended guidelines, you can significantly reduce the risk of contracting typhoid fever.

Who should not receive the Typhoid Vaccine?

While the typhoid vaccine is generally safe and well-tolerated, there are some exceptions. Individuals with compromised immune systems, such as those diagnosed with HIV or undergoing treatment for another disease, should consult their healthcare provider before receiving the Ty21a vaccine. However, there is no evidence to suggest that either typhoid vaccine is unsafe for pregnant or breastfeeding women. Additionally, the typhoid vaccine is not recommended for children under 6 years of age.

When should I get the Typhoid Vaccine?

To ensure optimal protection against typhoid fever, it is important to receive the typhoid vaccine at least 1 month before your travel date. This time frame allows your body sufficient time to develop immunity. If you frequently travel to high-risk areas, it is advisable to re-administer the vaccine every 3 years.

Potential Side Effects

Like any medical intervention, the typhoid vaccine may have some mild side effects. These can include soreness, redness, swelling, tenderness around the injection site, and, in rare cases, a high fever (38°C or more). These symptoms typically subside within a few days.

Other recommendations to prevent infection:

In addition to receiving the typhoid vaccine, there are other important precautions you should take while travelling to high-risk areas:

1. Drink water only from sealed bottles or water that has been recently boiled.
2. Avoid having ice in your drinks.
3. Avoid consuming raw fruits and vegetables unless they have been washed thoroughly in safe water or peeled by yourself.
