BCG vaccination / Tuberculosis (TB) vaccine

BCG Vaccine

BCG is the vaccine for Tuberculosis (TB) and has been used in the fight against TB for over 100 years. To date, the TB vaccine remains as the most widely used vaccine worldwide and has been given to more than 4 billion individuals with astonishing safety records.

Why is the BCG vaccine important?

The BCG vaccine is very effective for infants and children in protecting against the severe forms of TB. Furthermore, research has shown that BCG vaccination helps protect adults and children against non-TB mycobacterium, including leprosy, as well as upper and lower respiratory tract infections, such as pneumonia and influenza.

The effects of TB

TB is caused by the bacterium mycobacterium tuberculosis. TB not only affects the lungs, but can also affect the brain, spine and cause widespread (disseminated) TB disease, particularly in infants and children. It can cause serious illness and death if left untreated.

When will the BCG vaccine take effect?

BCG immunisation takes 4-8 weeks to build an immune response and it can take up to 3 months to take full effect. Therefore, BCG vaccination should be scheduled soon after your travel plans have been confirmed.

BCG Vaccine Research

Does BCG vaccination work to stop Tuberculosis (TB)? Emerging research shows BCG immunisation provides protection not only against TB, but even other non-TB infections. The BCG vaccine helps to protect not only TB disease (active TB), but also TB infection (latent TB). BCG vaccination is worthwhile, as it ensures greater protection against TB, the world's number one infectious disease.
