Singapore: A report by Australia's News Limited has revealed that a 15-year-old girl named Chloe Glasson has been suffering from narcolepsy four months after being injected with Pandemrix, a swine flu vaccine that is manufactured by GlaxoSmithKline (GSK). Ms Glasson, who was injected the vaccine during November 2009, has been falling asleep up to 30 times a day after getting a flu shot.

Ms Glasson will begin a new treatment of the specialist drug sodium oxybate at the Royal Hospital for Sick Children in Edinburgh, UK, in hopes to get back to a normal sleeping pattern.

GSK said in a statement that they are researching how narcolepsy is reportedly triggered for some by the drug. "Patient safety is our number one priority and we are researching how narcolepsy is triggered and how this vaccine might have interacted with other risk factors in affected individuals. We hope ongoing research efforts will enable us to provide more answers," GSK told News Limited in a statement.
