If a patient recently received a blood product, can he or she receive MMR vaccine?

Yes, but there should be sufficient time between the blood product and the MMR to reduce the chance of interference. The interval depends on the blood product received. See Table 3-6 of ACIP’s “General Best Practice Guidelines for Immunization” for more information, available at www.cdc.gov/vaccines/hcp/acip-recs/general-recs/timing.html.
