During mid-day the vaccinators find that all the Ice Packs have melted and the VVMs of OPV vials in the Vaccine Carrier are in stage II (this is usually the case when Ice Packs cannot be properly frozen overnight due to insufficient & erratic electric supply). While continuing administration of OPV from one vial, the workers shift remaining vials to a domestic refrigerator available near the Booth. This practice is continued till the end of the day maintaining VVMs do not cross stage IIâ€
