Which of the following statements is/are correct regarding the Td vaccine recently integrated into India's Universal Immunization Programme? 1. The 'd' in the Td vaccine stands for a reduced dose of the diphtheria toxoid formulated specifically for adults and adolescents. 2. The NTAGI recommends the Td vaccine only for adolescents, explicitly excluding pregnant women.

Question

Accepted Answer

A. 1 only — Statement 1 is correct as the lower-case 'd' indicates a reduced antigen concentration suitable to minimize side effects in adult boosters. Statement 2 is incorrect because the NTAGI recommends replacing the TT vaccine with Td for all eligible age groups, which explicitly includes pregnant women to prevent maternal and neonatal infections.
