TB Shots and the BCG Vaccine: What You Need to Know Before Travelling

Tuberculosis remains a serious infectious disease affecting thousands of people in the UK and millions worldwide. While most people associate TB with treatment, there is an important preventive option available: the BCG vaccination. At King’s Pharmacy in Birmingham, our travel vaccination clinic provides expert advice on TB prevention for travellers and those at increased risk.

Is There a Shot or Vaccine for Tuberculosis?

Yes. The BCG vaccine, which stands for Bacillus Calmette-Guerin, is the only currently available vaccine for tuberculosis. It has been in use for over a century and remains an important public health tool in countries with higher rates of TB. The BCG vaccine does not guarantee complete protection against TB infection, but it offers meaningful protection against severe forms of the disease, particularly in children, including tuberculous meningitis and disseminated TB, which can be life-threatening.

The NHS provides guidance on the BCG vaccine, including who it is recommended for and where it is available. If you are unsure whether you or your child needs the BCG vaccine, our pharmacy team can advise based on your circumstances and travel history.

Who Should Consider a TB Shot or BCG Vaccination?

The BCG vaccine is not part of the routine childhood immunisation schedule in the UK for everyone, but it is recommended for specific groups. Understanding whether you fall into one of these groups is the first step in assessing whether you need a TB shot before travelling or due to your circumstances at home.

GroupReason for RecommendationWhere to Access
Babies born in areas with high TB ratesHigher community transmission riskNHS maternity or GP service
Babies with a parent or grandparent from a high-incidence countryIncreased familial exposure riskNHS or travel vaccination clinic
Travellers to high TB prevalence countriesIncreased exposure risk in rural or healthcare settingsKing’s Pharmacy travel vaccination clinic
Healthcare workers with potential TB exposureOccupational risk of contact with active TB casesOccupational health or travel clinic
Unvaccinated individuals under 35 at riskBCG is generally less effective when given to new recipients over age 35; individual assessment is still recommendedKing’s Pharmacy travel vaccination clinic

How Does the BCG Tuberculosis Vaccine Work?

The BCG vaccine is a live attenuated vaccine, meaning it uses a weakened form of the Mycobacterium bovis bacterium, which is closely related to the TB bacterium. When injected, it stimulates the immune system to produce a response that offers protection against the most serious forms of TB disease. It is given as a single injection into the skin of the upper arm and typically leaves a small scar at the injection site.

It is important to note that the BCG vaccine does not prevent latent TB infection entirely, and its efficacy varies depending on geography and the strain of TB circulating in a given region. To understand more about how TB spreads and the risk factors involved, read our guide on how do you get TB.

Are There Any Side Effects From the TB Vaccination?

Most people tolerate the BCG vaccine well. The most common side effect is a small blister or sore at the injection site that develops within a few weeks, eventually forming a small flat scar. Some people experience mild swelling of the lymph nodes near the injection site. Serious side effects are rare but can include a larger local reaction or, in very rare cases in immunocompromised individuals, a more widespread BCG infection. Our clinicians will discuss any relevant risks with you before administering the vaccine.

TB Prevention Beyond Vaccination: What Travellers Need to Know

While the BCG vaccine is an important protective measure, it is not the only consideration for travellers heading to regions with higher TB prevalence. Prolonged close contact with people who have active TB remains the primary transmission route, so awareness of your surroundings and the nature of your travel is equally important. Healthcare workers, long-term travellers, and those staying in local community settings are at higher risk than those on short tourist trips.

TB is not the only respiratory infection worth considering when travelling. If you are planning a trip to a region with other health risks, our team can provide a comprehensive travel health assessment covering all relevant vaccinations and preventive measures. You may also find our guide on whether pneumonia is contagious useful for understanding respiratory infection risks more broadly.

Frequently Asked Questions About TB Shots and the BCG Vaccine

Is the BCG vaccine the same as a TB shot?

Yes. The BCG vaccine is the tuberculosis vaccination, commonly referred to as a TB shot. It is the only vaccine currently available that offers protection against TB. Two doses are associated with high rates of immune response, and vaccinated individuals who do develop TB typically experience a milder illness than those who are unvaccinated. It is given as a single intradermal injection and is recommended for specific at-risk groups in the UK, including babies in higher-risk areas and travellers to high-prevalence countries.

Can adults get the BCG vaccine in the UK?

Yes, but with some important caveats. The BCG vaccine is generally recommended for unvaccinated individuals under the age of 35 who are at increased risk of TB. Evidence suggests the vaccine is less effective when given to adults over 35 who have not previously been vaccinated. A tuberculin skin test or IGRA blood test is usually carried out first to check whether you have already been exposed to TB, as the vaccine is not given to those who test positive.

How long does the BCG vaccine protect against TB?

The duration of protection offered by the BCG vaccine varies. Studies suggest it provides meaningful protection for up to 15 years in some populations, though this varies by geography and individual factors. It is generally not given as a booster, as repeat doses have not been shown to enhance protection. Our team at King’s Pharmacy can advise on your individual risk and whether any additional precautions are recommended.

Does the BCG scar mean the vaccine has worked?

A small scar at the injection site is a normal and expected outcome of the BCG vaccine, but its presence or absence does not reliably indicate whether the vaccine has been effective. Some people develop a clear scar while others have a minimal reaction, and both can have a similar level of immune response. If you have concerns about your vaccination, speak to our team or your GP.

Where can I get the BCG vaccine in Birmingham?

The BCG vaccine is available at King’s Pharmacy through our Birmingham travel vaccination clinic. We offer pre-travel consultations that include a TB risk assessment and can arrange the vaccine for eligible individuals. Contact our team to book an appointment, and we will guide you through the process, including any prior skin testing that may be required.
