The Open Vial Policy (OVP) does NOT apply to which of the following vaccines?
- A Oral Polio Vaccine (OPV)
- B BCG vaccine ✓
- C DPT vaccine
- D Hepatitis B vaccine
Correct answer: B. BCG vaccine
Explanation
The Open Vial Policy allows certain multi-dose vaccines to be used across multiple immunization sessions if stored correctly and VVM is intact. BCG is EXCLUDED from OVP because it contains live bacteria that lose viability rapidly once reconstituted; all reconstituted BCG must be discarded within 2–4 hours. OPV, DPT, Hepatitis B, and TT are included in OVP.
