The Open Vial Policy under UIP states that which of the following vaccines can be used in subsequent immunization sessions after the vial has been opened?
- A BCG vaccine
- B Oral Poliovirus Vaccine (OPV) ✓
- C Measles-Rubella (MR) vaccine
- D Rotavirus vaccine
Correct answer: B. Oral Poliovirus Vaccine (OPV)
Explanation
The Open Vial Policy (OVP) allows multi-dose vials of certain vaccines to be used in subsequent immunization sessions (up to 28 days) if the cold chain has been maintained, the VVM has not reached the discard point, and aseptic technique was used. OPV, DPT, DT, TT, Pentavalent, and Td vaccines follow OVP. BCG, MR, measles, JE, and Rotavirus vaccines do NOT follow OVP — once opened they must be discarded at the end of the session.
