The UK's medicines regulator is examining a possible link between a swine flu vaccine given to millions of Britons and the sleeping disorder narcolepsy.
The Medicines and Healthcare products Regulatory Agency (MHRA) said it is "evaluating" case reports in Europe of patients developing narcolepsy after taking the drug Pandemrix.
Made by GlaxoSmithKline, the vaccine was the most widely used in the UK at the height of last year's flu pandemic.

A spokesman for the MHRA said it was "aware of the case reports of narcolepsy" and was "evaluating these in collaboration with other EU authorities".
"Narcolepsy is a rare, natural illness, with around 10 new cases per million people every year and at present no link with the vaccine has been established," he added. "After use of more than six million doses of swine flu vaccine in the UK, no cases of narcolepsy have been reported following vaccination in the UK. Pandemrix vaccine remains available for use as recommended."
