BCG:
BCG is given on the left shoulder. Within 3 - 6 weeks (sometimes a few months) of giving BCG a small swelling/ redness appears at the site of injection. The swelling will soften and subsequently rupture discharging pus. This ulcer takes several weeks to heal, leaving behind a scar. The ulcer should be kept dry and cleaned with soap and water. No ointment/cream is required. There may be an associated swelling in the armpit or in some cases on the neck. It is nothing to be worried about, but if the swelling increases more than 1 cm in diameter or becomes red or soft or attached to the overlying skin, consult your doctor. This swelling may persist for months or years.



If no reaction or mark is seen at BCG injection site after 3 months, consult your doctor. BCG significantly decreases the risk of tuberculous meningitis (Brain TB) and other widespread forms of tuberculosis.
