The pentavalent vaccine used in India's UIP contains which five antigens?
- A DPT + Hib + Hepatitis B ✓
- B DPT + Hib + IPV
- C DPT + Hepatitis B + IPV
- D DPT + Hib + Hepatitis A
Correct answer: A. DPT + Hib + Hepatitis B
Explanation
The pentavalent vaccine used in India's Universal Immunization Programme combines Diphtheria, Pertussis, Tetanus (DPT), Haemophilus influenzae type b (Hib), and Hepatitis B — five antigens in one injection. It is given at 6, 10, and 14 weeks along with OPV (and fIPV intradermally at 6 and 14 weeks). Introduction of pentavalent vaccine replaced separate Hep B and DPT injections, reducing the number of injections at each visit. IPV was added separately, not as part of pentavalent.
