HELSINKI (AP)- Finnish health officials say they have found an increased risk of narcolepsy among 4 to 19-year-olds who were given swine flu shots.
The National Narcolepsy Task Force says a preliminary study indicates that children vaccinated with Pandemrix "contributed to the observed increase in incidence of narcolepsy" compared to those who were not vaccinated in the same age group.
The study published by Finland's National Institute for Health and Welfare Tuesday says that "the most likely explanation is that the increase in narcolepsy is by joint effect of the vaccine and some other factor."
In August, the European Medicines Agency said it was investigating a possible link between the swine flu vaccine and narcolepsy, a rare disorder that causes people to suddenly fall asleep.
