Seasonal flu vaccines 2010: No evidence of an increased risk of febrile convulsions in children
In Australia, an excess risk of febrile convulsions (fever fits in children) has been associated with one brand of flu vaccine (Fluvax, manufactured by CSL). Therefore, as a safety measure in the UK, the Department of Health advised doctors not to use flu vaccines manufactured by CSL in children age less than 5 years, but to use alternative vaccine brands instead. In addition, the MHRA monitored reports of febrile convulsions in this year's UK flu vaccination campaign, and analysed whether the reports were more frequent than would have occurred naturally. The analysis found that reports of febrile convulsion received this year in the UK are within the natural range, and that there is no indication of an excess risk of febrile convulsions in children following seasonal flu vaccination.
