After which age BCG vaccine should not be given–

Correct option is B

Sol. As per Government of India and WHO guidelines, BCG vaccine should not be administered after 1 year of age if the child has not received it earlier. This is because efficacy declines with increasing age and the likelihood of prior exposure to tuberculosis increases, which could alter immune response. However, it may be given after 1 year if tuberculin test is negative and recommended by a physician.
Explanation of each option:
· (a) 6 Months – Incorrect. BCG can be safely given up to 12 months of age without requiring tuberculin testing.
· (b) 1 year – Correct. After this age, BCG is usually not recommended, unless medically indicated and tuberculin-negative.
· (c) 2 year – Incorrect. Beyond this age, even if missed, BCG is not routinely administered as per national guidelines.
· (d) 5 years – Incorrect. BCG is ideally a neonatal vaccine and not advised in this age group under routine immunization.
