The open vial policy under the National Immunization Schedule does NOT apply to which of the following vaccines?

• A Measles-Rubella (MR) vaccine ✓
• B Oral Polio Vaccine (OPV)
• C Hepatitis B vaccine (in multi-dose vials)
• D Rotavirus vaccine

Explanation

The open vial policy allows multi-dose vials to be used in subsequent sessions if stored correctly (2-8°C), with VVM in acceptable stage, cap intact, and within expiry. This applies to OPV, Hepatitis B (10-dose vials), and liquid formulations. Measles-Rubella (MR) vaccine is a reconstituted vaccine — once reconstituted, it must be discarded at the end of the session or within 4 hours, whichever is earlier. It is NOT covered under open vial policy.
