The risk
of a febrile seizure following the MMR is approximately one case in 3,000 doses for children aged 12 to 15 months but one case in 1,500 doses for children aged 16 to 23 months «This study adds to the evidence that the best way to prevent disease and minimize side effects from vaccines is to vaccinate on the recommended schedule,» says Simon Hambidge, lead author of the study and the director of general pediatrics at Denver Health.
The researchers found a slight increase in the relative risk
of febrile seizure with the MMRV vaccine compared with the MMR+V vaccine — about 1 excess seizure for every 2841 doses administered in the 7 - to 10 - day period after vaccination.
«Although we find a slightly increased risk

However, the combined vaccine has been associated with slightly higher rates
of febrile seizures.
To determine whether there is an increased risk
of febrile seizures from the combined vaccine, researchers looked at data on 227 774 children aged 12 to 23 months who received either the MMR+V or the MMRV vaccine between 2006 and 2012 in Alberta, Canada.
