What countries have vaccine for tuberculosis?

Countries around the world administer the Bacillus Calmette-Guérin (BCG) vaccine for tuberculosis (TB), which is primarily given to infants and young children to prevent severe forms of TB. BCG vaccination is widely used in many countries, particularly in Asia, Africa, and parts of Europe, where TB is more prevalent. While the vaccine is not routinely given in some high-income countries where TB rates are low, it remains a part of immunization programs in countries with higher incidence rates.
