Following withdrawal of tOPV, the Universal Immunization Programme schedule includes fractional inactivated poliovirus vaccine (fIPV) given intradermally. The correct ages for the two fIPV doses are:
- A At birth and at 6 weeks
- B At 6 weeks and at 14 weeks ✓
- C At 14 weeks and at 9 months
- D At 9 months and at 16 to 24 months
Correct answer: B. At 6 weeks and at 14 weeks
Explanation
Fractional intradermal IPV (0.1 ml) replaced the former full-dose intramuscular schedule in routine immunization and is administered at 6 weeks and 14 weeks alongside pentavalent and OPV. Birth-dose contacts receive OPV zero dose, not injectable polio vaccine. The 9 month and 16 to 24 month contacts correspond to MR1 and MR2 along with OPV boosters, not fIPV. Intradermal fractional dosing achieves comparable priming with one fifth of the antigen volume.
