Route of BCG vaccine?

Concept-

• The Bacille Calmette Guerin vaccine was developed by French bacteriologists Albert Calmette and Camille Guerin.
• The BCG vaccine is a vaccine generally used to prevent tuberculosis.
• In countries where tuberculosis or leprosy is common, one dose of the BCG vaccine is recommended for newborn babies as soon as they are born.
• BCG vaccine is a live attenuated vaccine designed to help people become immune from TB.

Important Points

• The BCG vaccine route is different from all other vaccines. The BCG vaccine route requires an intradermal (ID) injection.
• ID BCG injection administers the vaccine into the top layer of the skin. Intradermal BCG injection reduces the risk of neurovascular injury but may leave scarring of the BCG vaccine.
• The BCG vaccine is the most difficult vaccine to administer due to the small size of the newborn's arms.
• A small narrow needle (15 mm, 26 gauge) is used to administer the BCG vaccine. The standard dose for BCG vaccination is 0.1 g in 1 mL.
• The dose of BCG vaccine for children under 1 year of age is 0.05 mL. Children above 1 year have to take the standard dosage.
