Under the Revised National Immunization Schedule (NIS) of India as per the latest UIP guidelines, Pneumococcal Conjugate Vaccine (PCV) is given as a 3-dose schedule. The schedule is:

• A 6 weeks, 10 weeks, 14 weeks (3p+0)
• B 6 weeks, 14 weeks, 9 months (2p+1 booster) ✓
• C 6 weeks, 10 weeks, 14 weeks, and a booster at 9 months (3p+1)
• D 9 months, 12 months, 15 months

Explanation

India's UIP introduced PCV in a 2+1 schedule: two primary doses at 6 weeks and 14 weeks, with a booster dose at 9 months given simultaneously with Measles-Rubella (MR) and JE vaccines. This 2p+1 schedule is recommended by WHO and provides equivalent immunogenicity with fewer doses, improving compliance and reducing programme cost. The 3p+0 schedule without a booster was the earlier approach used in the initial rollout phase before the national scale-up.
