How Does the BCG Vaccine Work?The BCG Vaccine helps the immune system recognize and fight Mycobacterium tuberculosis, the bacteria responsible for causing tuberculosis, particularly its severe manifestations in young children. By introducing a live attenuated strain of Mycobacterium bovis, the vaccine primes the body's defenses to respond rapidly if exposed to TB in the future.
Proper Reconstitution and UsageBefore administration, the BCG Vaccine requires reconstitution with exactly 1.0 ml of the provided diluent. After mixing, the product should be used within six hours and must not be stored overnight. Intradermal injection is the only recommended route, and correct dosage (0.1 ml for newborns and infants) ensures efficacy and safety as per medical guidance.
Who Should Receive the BCG Vaccine?The BCG Vaccine is recommended for newborns and children under the age of one, especially in regions with high TB prevalence. It is administered in hospitals, clinics, or by authorized immunization programs worldwide. The vaccine should not be given to individuals with immunocompromised states, symptomatic HIV, severe illness, or active TB infection.
