  • MMR (Measles, Mumps, and Rubella)
  • Storage & Handling

Once MMR vaccine has been reconstituted with diluent, how soon must it be used?

The guidance for handling after reconstitution is the same for both brands of MMR vaccine (MMRII and Priorix). It is preferable to administer MMR immediately after reconstitution. If not used immediately, the reconstituted vaccine should be store refrigerated (2°C to 8°C [36°F to 46°F]) until use. If reconstituted MMR is not used within 8 hours, it must be discarded.
