Under the National Immunization Schedule, the fractional inactivated polio vaccine (fIPV) is administered by which route and at what dose volume?

• A Intramuscular, 0.5 mL
• B Oral, 2 drops
• C Subcutaneous, 0.5 mL
• D Intradermal, 0.1 mL ✓

Explanation

Fractional IPV is given intradermally at a dose of 0.1 mL, one-fifth of the full intramuscular dose. India introduced fIPV in 2016 at 6 and 14 weeks of age to stretch limited IPV supply while maintaining immunity. The intradermal route uses a smaller volume and is cost-effective.
