- Had any sort of a reaction to a vaccine
- A moderate or severe illness
- Had a recent blood transfusion (or have recently received any other blood products)
- Seizures or epilepsy
- A low blood platelet count
- A malignant blood or lymph disorder, such as leukemia or lymphoma
- Any allergies, including to foods, dyes, or preservatives.
Also, let your healthcare provider know if you are:
- Pregnant or thinking of becoming pregnant (see MMR and Pregnancy)

How Should MMR Be Stored?The lyophilized (freeze-dried) portion of MMR should be stored in the refrigerator. 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 in the refrigerator for up to eight hours.
