There are two different formulations of MMRV: the "refrigerator stable formulation" and the "frozen formulation." The lyophilized (freeze-dried) portion of MMRV should be stored in the refrigerator or freezer (for the "refrigerator stable formulation") or the freezer (for the "frozen formulation"). The liquid portion can be stored in the refrigerator or at room temperature.
After the two have been mixed together, the vaccine should be used as soon as possible, but may be stored at room temperature for up to 30 minutes.
