Ninety-three people in Sweden, most of them children, have been diagnosed with narcolepsy since taking the swine flu vaccine Pandemrix last winter, according to figures from the Swedish Medical Products Agency (Läkemedelsverket).
In 88 of the 93 cases, the agency has identified a direct correlation between the vaccine and the onset of narcolepsy, a sleep disorder causing extreme drowsiness and daytime sleep attacks.
According to the Swedish Association of Persons with Neurological Disabilities (Neurologiskt handikappades riksförbund – NHR), the agency is examining a further 135 cases involving children and will present its full findings later this summer.
NHR announced on Friday the launch of a 250,000 kronor ($40,000) research grant to facilitate studies of the relationship between Pandemrix, a drug manufactured by pharmaceutical giant GlaxoSmithKline, and narcolepsy.
“We are deeply concerned and have decided that things needs to happen, and quickly,” said NHR chair Kathleen Bengtsson-Hayward in a statement.
