Is there an increased risk of fever or febrile seizures associated with the MMRV vaccine when it is used as a second dose?
Studies do not suggest that children who are 4 through 6 years old and receive the MMRV vaccine have an increased risk of febrile seizures after vaccination when compared with those who receive the MMR and varicella vaccines at the same doctor visit. In addition, the second dose of MMRV vaccine is less likely to cause fever than the first dose. For the second dose given at any age (15 months through 12 years), use of the MMRV vaccine is generally preferred over using the MMR and varicella vaccines because it requires one less injection to provide similar protection with no known additional risks of side effects. [See the ACIP Provisional Recommendations.
