The [[MMRV vaccine]], a combined measles, mumps, rubella, and [[varicella]] (chickenpox) vaccine, has been proposed as a replacement for the MMR vaccine to simplify the administration of the vaccines.<ref name=Vesikari>{{cite journal | vauthors = Vesikari T, Sadzot-Delvaux C, Rentier B, Gershon A | title = Increasing coverage and efficiency of measles, mumps, and rubella vaccine and introducing universal varicella vaccination in Europe: a role for the combined vaccine | journal = The Pediatric Infectious Disease Journal | volume = 26 | issue = 7 | pages = 632–638 | date = July 2007 | pmid = 17596807 | doi = 10.1097/INF.0b013e3180616c8f | s2cid = 41981427 }}</ref> Preliminary data indicate a rate of [[febrile seizures]] of 9 per 10,000 vaccinations with MMRV, as opposed to 4 per 10,000 for separate MMR and varicella shots; US health officials therefore, do not express a preference for use of MMRV vaccine over separate injections.<ref name=klein08>{{cite journal | title = Update: recommendations from the Advisory Committee on Immunization Practices (ACIP) regarding administration of combination MMRV vaccine | journal = MMWR.

After reading an informational statement only 7% of family doctors and 20% of pediatricians would recommend the MMRV for a healthy 12- to 15-month-old child. The factor that was reported as the "most important" deciding factor in recommending the MMRV over the MMR+V was [[Advisory Committee on Immunization Practices|ACIP]]/[[AAFP]]/[[American Academy of Pediatrics|AAP]] recommendations (pediatricians, 77%; family physicians, 73%).
