Is there an increased risk for febrile seizures after children receive a flu shot?
Several studies of children in the United States have not shown an increased risk for febrile seizures after they received their seasonal influenza shots. One study included more than 45,000 children aged 6 months–23 months who received influenza vaccines during the years 1991–2003. Multiple systems are in place to monitor adverse events, including seizures, after 2009-2010 H1N1 influenza vaccines. As with seasonal influenza vaccine, there is no indication that the 2009-2010 H1N1 vaccines being used in the United States are associated with an increased risk for febrile seizures. Febrile seizures can occur, however, after a child catches the flu.
