In a 2012 study  pediatricians and family doctors were sent a survey to gauge their awareness of the increased risk of febrile seizures (fever fits) in the MMRV. 74% of family doctors and 29% of pediatricians were unaware of the increased risk of febrile seizures. 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 ACIP/AAFP/AAP recommendations (pediatricians, 77%; family physicians, 73%).
The MMR vaccine is safe and effective. Most individuals will have no reaction. The vaccine can cause a malaise and fever, possibly with a rash, in approximately five per cent of children six to 23 days after MMR immunization. Allergic reactions to the MMR vaccine are very rare. There is no evidence that the MMR vaccine causes autism.
The vaccine is safe for household members of people with immune system problems and household members of pregnant women. Breastfeeding women can receive the MMR vaccine.
Speak with your health care provider or local public health unit about the benefits and risks of the vaccine, as well as the risks of not getting vaccinated.
