BCG vaccination should be given within what timeframe after birth in settings where routine BCG is given?

• A. Within 6 months
• B. Within 4 weeks of life
• C. Within 1 year
• D. Within 2 weeks

Answer: (B)

Vaccinate early to protect infants during the period of highest risk for severe TB. In settings where routine BCG is given, the best practice is to administer it within the first four weeks of life. This ensures protection is in place during early infancy, when exposure risk is greatest and the impact of BCG on preventing severe TB (like TB meningitis and miliary TB) is most beneficial. Delaying beyond four weeks reduces the timeliness of protection, while waiting much earlier (within a couple of weeks) fits the same general window, but four weeks is the standard reference period used in guidelines. Waiting until six months or a year would leave infants unprotected during a vulnerable phase.
