What is BCG vaccine?
Tuberculosis is a contagious bacterial disease caused by the bacillus Mycobacterium tuberculosis. Tuberculosis is the second leading cause of death from infectious diseases throughout the world, after acquired immune deficiency syndrome (AIDS). BCG (Bacillus Calmette and Guerin) vaccine provides immunity or protection against tuberculosis (TB). BCG Vaccine is a live freeze-dried vaccine derived from attenuated strain of Mycobacterium bovis. The vaccine is intended to be injected strictly via the intradermal route, avoiding the subcutaneous route.
BCG Immunization schedule
This vaccine should be given soon after the child is born. BCG administered early in life provides high level of protection particularly against sever forms of childhood tuberculosis and tubercular meningitis.
Effectiveness
BCG vaccine protects against serious TB disease for up to 15 years after vaccination.
Side effects
BCG immunization generally causes some pain and scarring at the site of injection. Two to six weeks after the injection, a small spot may appear at the site of the injection. The spot can be painful and bruised for a few days, but will eventually heal. Occasionally, there may be a more severe skin reaction, but this should heal within a few weeks. If you are worried that you or your child’s skin reaction is abnormal or that the spot may have become infected, contact your Doctor.
