As per the current National Immunization Schedule, fractional inactivated poliovirus vaccine (fIPV) is administered to an infant at 6 weeks and 14 weeks. The correct technique is:
- A 0.1 mL intradermally, right upper arm at 6 weeks and left upper arm at 14 weeks ✓
- B 0.5 mL intramuscularly in the anterolateral thigh on both occasions
- C 0.1 mL subcutaneously in the left upper arm on both occasions
- D 0.05 mL intradermally over the deltoid region bilaterally at each visit
Correct answer: A. 0.1 mL intradermally, right upper arm at 6 weeks and left upper arm at 14 weeks
Explanation
Fractional IPV under India's UIP is 0.1 mL given intradermally, alternating arms: right upper arm at 6 weeks and left upper arm at 14 weeks, using a 26 G, 10 mm needle with bevel facing upward. The intramuscular full dose belongs to countries using whole-dose IPV schedules, not India's fractional approach. Subcutaneous route and bilateral simultaneous administration are not recommended.
