Each ampoule of vaccine contains :
• Live attenuated Bacillus Calmette-Guerin 1.5 mg
Diluent consist of :
• Sodium Chloride 0.9 %
Active immunization against tuberculosis.
Mechanism of action
Stimulates the body to produce antibody against tuberculosis.
The local reaction after BCG immunization is normal.
A small tender red swelling appears at the injection site, which than changes to a small vesicle, and than become ulcer in 2-4 weeks. This reaction usually disappears after 2-5 months, and generally in a child will result a scare with 2-10 mm in diameter.
Rarely the nodus and ulcer keep remaining. Occasionally, enlargement of axillary lymph nodes may appear in 2-4 months following immunization.
Very rarely, enlarged lymph nodes suppurate. Inadvertent subcutaneous injection may produce abscess formation and may lead to scarring.
