Risk of febrile seizures after first dose of measles–mumps–rubella–varicella vaccine: a population-based cohort study

Abstract

Despite an increased risk of febrile seizures following MMRV (compared with MMR+V), the absolute level of risk was small. Policy-makers need to balance these findings with the potential benefits of administering the combination vaccine or determine whether the choice of vaccine rests with clinicians and/or parents.
