Vaccination
Bacillus Calmette–Guérin (historically Vaccin Bilié de Calmette et Guérin commonly referred to as Bacille de Calmette et Guérin or BCG) is a vaccine against tuberculosis and for the treatment of some bladder cancers.
It is prepared from a strain of the attenuated (virulence-reduced) live bovine tuberculosis bacillus, Mycobacterium bovis, that has lost its virulence in humans. Because the living bacilli evolve to make the best use of available nutrients, they become less well-adapted to human blood and can no longer induce disease when introduced into a human host. Still, they are similar enough to their wild ancestors to provide some degree of immunity against human tuberculosis. The BCG vaccine can be anywhere from 0 to 80% effective in preventing tuberculosis for a duration of 15 years; however, its protective effect appears to vary according to geography and the lab in which the vaccine strain was grown.
It is on the World Health Organization’s List of Essential Medicines, a list of the most important medication needed in a basic health system.
Medical uses
The main use of BCG is for vaccination against tuberculosis. BCG vaccine can be administered after birth intradermally.BCG vaccination is recommended to be given intradermally. A previous BCG vaccination can cause a false positive Mantoux test, although a very high-grade reading is usually due to active disease.
The age of the patient and the frequency with which BCG is given has always varied from country to country.
WHO BCG policy: The WHO recommend BCG be given to all children born in countries highly endemic for TB because it protects against miliary TB and TB meningitis.INDIA: BCG vaccine needs to be given immediately after birth and catch.
Method of administration
BCG is given as a single intradermal injection at the insertion of the deltoid. If BCG is accidentally given subcutaneously, The characteristic raised scar BCG immunization leaves is often used as proof of prior immunization
Routine vaccination:
Minimum age: birth
• Administer monovalent HepB vaccine to all newborns within 48 hours of birth.
• Monovalent HepB vaccine should be used for doses administered before age 6 weeks.
• Administration of a total of 4 doses of HepB vaccine is permissible when a combination vaccine containing HepB is administered after the birth dose.
• Infants who did not receive a birth dose should receive 3 doses of a HepB containing vaccine starting as soon as
feasible.
• The ideal minimum interval between dose 1 and dose 2 is 4 weeks, and between dose 2 and 3 is 8 weeks. Ideally, the final (3rd or 4th) dose in the HepB vaccine series should be administered no earlier than age 24 weeks
and at least 16 weeks after the first dose,whichever is later.
