Under India's Universal Immunisation Programme, the Open Vial Policy (OVP) allows reuse of opened multi-dose vials in subsequent sessions, EXCEPT for which vaccine?

• A OPV (Oral Polio Vaccine)
• B Measles-Rubella vaccine
• C Pentavalent vaccine (DTP-Hib-HepB)
• D BCG vaccine ✓

Explanation

Under OVP, opened multi-dose vials of OPV, DPT, TT, Hepatitis B, liquid pentavalent and MR vaccines may be reused in subsequent sessions within 28 days if the cold chain is maintained and the vaccine vial monitor (VVM) is acceptable. BCG, however, must be discarded within 3 hours of reconstitution due to susceptibility to contamination and loss of potency, and is NOT covered by OVP.
