Tuberculin reactivity after neonatal percutaneous BCG immunisation.

A total of 348 neonates of Asian ethnic origin were given percutaneous BCG vaccination using a multiple puncture head. Fifty five (15.8%) were tuberculin negative when tested 6-9 weeks after vaccination, a significantly higher proportion than after intradermal vaccination. The number of abscesses after vaccination was however significantly lower.

Tuberculin skin reactivity four years after neonatal BCG vaccination.

Two hundred and sixty one of 279 (93.5%) children known to be tuberculin positive shortly after receiving their neonatal BCG vaccination were still tuberculin positive at age 4 years. The results confirm the continuing effectiveness of neonatal BCG at 4 years.
