As per the revised National Immunization Schedule (2023), which vaccine is given to a pregnant woman at 20 weeks of gestation for the first time?
- A Tetanus toxoid (TT) single dose
- B Inactivated influenza vaccine
- C Tdap (tetanus, diphtheria, acellular pertussis) single dose ✓
- D Hepatitis B vaccine
Correct answer: C. Tdap (tetanus, diphtheria, acellular pertussis) single dose
Explanation
India's revised NIS recommends a single dose of Tdap to pregnant women at 20 weeks of gestation, replacing the earlier two-dose TT schedule. This protects neonates from pertussis in early infancy through transplacental antibody transfer.
