The European Centre for Disease Prevention and Control has found that the vaccination that was used to cure swine flu in 2009-10 has caused sleeping problems in many children in European countries. During the 2009-10 swine flu outbreak, Pandemrix vaccine was administered to many children with the aim of preventing them from the disease.

But, it seems like the vaccination has caused yet another problem as children are now finding it hard to get adequate sleep. The European Centre for Disease Prevention and Control (ECDC) said, "The case-control study found an association between vaccination with Pandemrix and an increased risk of narcolepsy in children and adolescents (five to 19 years of age) in Sweden and Finland".

Although a link between the vaccination and sleeping disorder has been found in Sweden and Finland, no such link has been found in any other European countries. The vaccination is produced by GlaxoSmithKline.

It has been informed that narcolepsy is a disorder in which a person can even succumb to paralysis. Drowsiness and hallucination are being experienced by the kids in Sweden and Finland. Children affected with narcolepsy are now being studied so that best treatment could be provided.
