BCG Vaccine in Children: Essential Information for Parents Injection Site & Route The BCG (Bacillus Calmette-Guérin) vaccine is administered intradermally (just under the skin). It is usually injected into the upper left arm (deltoid region).
Schedule At Birth: Typically given soon after birth, especially in areas with high rates of tuberculosis (TB).
Catch-up Vaccination: Can be given up to 5 years of age if missed at birth, but earlier vaccination provides better protection. Benefits of the BCG Vaccine Prevents Severe TB: Protects against severe forms of tuberculosis, such as miliary TB and TB meningitis, which are more dangerous in young children. Reduces TB Spread: Though it may not fully prevent TB lung infections, the BCG vaccine lowers the severity and spread of the disease, especially in high-risk regions.
Long-term Immunity: Typically offers long-lasting protection against severe tuberculosis, reducing the risk of life-threatening complications.
Side Effects Swelling or Redness: Mild swelling or redness may occur at the injection site, and a small ulcer can form, which heals within weeks. Scar Formation: A small scar usually develops at the injection site, a normal outcome of the vaccine.
Mild Fever: Some children may develop a low-grade fever, which typically resolves on its own. Severe side effects are extremely rare, making the BCG vaccine very safe for children. For any concerns or questions about the BCG vaccine, consult your pediatrician.
