The BCG (Bacillus Calmette-Guérin) vaccination is given at birth, primarily to protect newborns at risk of getting tuberculosis (TB). TB is a severe infectious disease that can lead to TB meningitis in babies.
Understanding the Importance of Early BCG Vaccination
Giving the BCG vaccine soon after birth provides early protection against severe forms of TB that are most dangerous to infants and young children. Here's a breakdown of why this early vaccination is crucial:
- Protection Against Severe Forms of TB: BCG is most effective in preventing disseminated TB, like TB meningitis (inflammation of the brain and spinal cord) and miliary TB (TB that spreads throughout the body). These forms are particularly life-threatening for infants.
- Vulnerability of Newborns: Newborns have immature immune systems, making them more susceptible to contracting TB and developing severe complications.
- Early Exposure Risk: In regions where TB is prevalent, there's a higher chance of newborns being exposed to the bacteria soon after birth. Vaccinating early provides immediate protection.
Benefits Summarized
