no. i do not believe that the flu vaccine causes narcolepsy. as a matter of fact the cause of narcolepsy is really idiopathic (not known).
does the flu shot cause narcolepsy. i have been just informed that i have narcolepsy i have been reading online that the flu shot has caused narcolepsy in children. back in 1980s i was in the services and had to have a flu shot. could this have caused me to develop narcolepsy? i have never had a flu shot til i was in the service. the doctor told me that i have had this for several years and that it has begun to get worse. i will be 50 in may.
