Swine Flu Vaccine and Narcolepsy

Narcolepsy is a sleep disorder that causes excess sleepiness. It's not a common disorder, and can be hard to diagnose. There have been several news reports about the link between a flu vaccine given in Europe and narcolepsy. This report shows that there may be a link between the two. Researchers think that the immune system may be involved in development of narcolepsy, and that the vaccine tricks the immune system in predisposed individuals. However, correlation does not equal causation. More, larger studies are needed to show that narcolepsy may have been caused by this vaccine.
