Canadian Study Reports Combining Vaccines Doubles Risk of Febrile Seizures

Febrile seizure Managing Editor's Note: Pediatricians will "soft pedal" febrile seizures as if they are completely benign. My daughter's first seizure was called "febrile."  Her 673rd was called Grand Mal.....     Vaccination should not cause a baby to convulse. If a dose of Motrin caused convulsions the product would come off the shelf faster than my 17 year old can find Blue's Clues on YouTube...

Combined vaccine doubles seizure risk in children Vancouver Sun
Combining two common childhood vaccines into one — rather than administering them separately — doubles the risk of febrile seizures in children, a study published in the Canadian Medical Association Journal has found.

Febrile seizures — convulsions brought on by fever in infants or young children — are a rare side effect of measles-mumps-rubella vaccine, occurring at a rate of less than two seizures per 10,000 doses. When the MMR vaccine is combined with the vaccine against chickenpox, creating the MMRV (for varicella) vaccine, that risk doubles. It still remains relatively small, however — at a rate of 3.52 seizures per 10,000 doses, according to the study by a team led by Dr. Shannon MacDonald at the University of Calgary’s faculty of medicine. Seizures among high-risk children were not significantly different, the study also found.

Febrile seizures rarely have long-term effects, said MacDonald, but they do cause distress “and may undermine confidence in immunization programs.”   Read more.
