Vaccine slightly raises babies’ risk of febrile seizure










Danish researchers say a common combo vaccine may
slightly increase babies’ risk of developing febrile convulsion, a
fever associated seizure.

The combination vaccine known as DTaP-IPV-Hib protects kids against 5
life-threatening infections including diphtheria, tetanus, pertussis or
whooping cough, polio and Haemophilus influenzae type b, which causes
illnesses such as pneumonia and meningitis.

Previous study had suggested that an older version of the pertussis
vaccine could cause fevers and increase the risk of related seizure, but
it is not clear if the risk also applies to newer versions in combined
vaccines.

To study the risk, Yuelian Sun and colleagues from Aarhus University of
the Netherlands tracked more than 378,000 babies who received the
country’s routine DTaP-IPV-Hib vaccine at 3, 5, and 12 months old .

They investigated the incidence of febrile seizures in days after each
vaccination and the rate of epilepsy after receiving the first shot
among participants.

Overall, 7,811 children were diagnosed with febrile seizures before
they were 18 months old. The vast majority of the seizures were found to
be caused by infection fever.

The results also showed that the uncommon febrile seizures were
unlikely to increase the risk of epilepsy in children, says the report
in the Journal of the American Medical Association.

The findings suggest that the combo vaccine is safe for kids and
parents should continue to get their kids immunized on schedule to
protect them and others around them against life-threatening diseases.
