BCG Vaccine: Age, Timing, and Regional Variations

There is no one specific age at which a TB injection is given, as the timing of vaccination can vary depending on a number of factors, including the country and region where you live, your individual health status, and the recommendations of your healthcare provider.

In some countries, the TB injection, also known as the Bacillus Calmette-Guérin (BCG) vaccine, is given to infants at birth or shortly after as part of routine immunization programs. In other countries, it may be given later in childhood or adolescence, or it may not be routinely recommended at all.

If you are unsure about the recommended timing of the TB injection in your specific situation, it is best to consult with a healthcare professional for personalized advice.
