Children in England who were given a version of the swine flu vaccine between 2009 and 2010 were at increased risk of developing narcolepsy after they got the shot, a new study suggests.
The findings are similar to those of previous studies conducted in Finland and Sweden, which also found a link between the 2009 swine flu vaccine called Pandemrix (made by GlaxoSmithKline) and narcolepsy in children.
However, because a large number of people were vaccinated and narcolepsy is rare, a child's chances of developing the disorder following vaccination were extremely small, around 1 in 55,000. What's more, these studies still show only an association and cannot prove the vaccine caused narcolepsy.
