Influenza vaccine safety in children less than 5 years old: the 2010 and 2011 experience in Australia.

In August 2010, the United States Advisory Committee on Immunization Practices recommended that the 2010-2011 CSL seasonal vaccine (Afluria) not be administered to children 6 months to 8 years of age because of the risk of febrile convulsion after immunization. This study reports a low rate (6%-7%) of fever after immunization with 2 non-CSL brands of 2011 seasonal influenza vaccine in Australian children <5 years of age. These data are reassuring for parents and healthcare workers regarding 2011 influenza vaccination in the northern hemisphere.
