The BCG (Bacillus Calmette-Guérin) vaccine helps prevent tuberculosis (TB) in infants and young children. It introduces a weakened form of the live virus to help develop immunity against TB. It is very important for babies born in countries where TB is common.
In countries where TB is prevalent, the vaccine is given to the baby soon after birth or within the first few hours. In some countries, where the risk is lower, the vaccine can be given anytime within the first 6 months, before potential exposure to tuberculosis.
The vaccine produces a visible scar. It is generally given on the left upper arm, making it a standard procedure that facilitates easier identification during a routine check. The WHO recommends this site for the injection, so no matter which country you go to, it becomes easier for the doctors to confirm whether you have received the vaccination or not.
The BCG vaccine is given to babies who weigh more than 2 kg. However, for premature babies or underweight babies who weighed less than 2 kg at birth, the vaccination can be given when they are a month old or before being discharged from the hospital, whichever occurs first.
