Open vial policy is applicable to which of the following vaccine?
Appeared in: RUHS, Jaipur, PB B.Sc Nursing Entrance-2019
Explanation
- Hepatitis B vaccine is a liquid, multi-dose formulation containing a preservative, which are the primary criteria for inclusion in the Open Vial Policy (OVP).
- The OVP allows a partially used vial of Hepatitis B to be kept and used for up to 28 days in subsequent immunization sessions, provided strict cold chain and aseptic conditions are maintained.
- This policy is a WHO-endorsed strategy designed to minimize vaccine wastage for specific types of vaccines without compromising patient safety.
Why Other Options Were Wrong
- Option A: This is a lyophilized (freeze-dried) vaccine that must be reconstituted before use. It does not contain a preservative.
- Option B: Like the Measles vaccine, the Japanese Encephalitis (JE) vaccine is reconstituted from a freeze-dried powder and lacks preservatives.
- Option C: The Rotavirus vaccine (RVV) is a liquid vaccine but does not contain a preservative, making it ineligible for the OVP.

Clinical Relevance
- Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Application of the Open Vial Policy (OVP) for vaccines under the Universal Immunization Program (UIP) as background academic context rather than a clinical decision trigger.
- Correctly applying the Open Vial Policy is a critical nursing responsibility to ensure vaccine potency, prevent administration of contaminated vaccines, and minimize wastage, which is vital for public health program efficiency.
- Nurses must label any opened OVP-eligible vial with the date and time of the first opening. This ensures it is not used beyond the 28-day limit and helps in tracking.
- Patient safety is paramount. Before using any opened vial, the nurse must check the Vaccine Vial Monitor (VVM), ensure the expiry date has not passed, and confirm the cold chain was maintained.
How to Approach the Question
- First, identify the core concept of the question, which is the 'Open Vial Policy' (OVP).
- Recall the specific rules for OVP: it applies to LIQUID, MULTI-DOSE vaccines that contain a PRESERVATIVE.
- Analyze each option based on these rules.
- Measles and Japanese Encephalitis are reconstituted (lyophilized), so they are immediately disqualified.
- Rota Virus is a liquid vaccine but lacks a preservative, so it is also disqualified.
- Hepatitis B is a liquid, multi-dose vaccine that contains a preservative, making it the only correct choice.
