The national narcolepsy panel's interim report suggests that the Pandemrix vaccination increases the risk of narcolepsy nearly tenfold. It says that children aged 4 to 19 were at nine times greater risk of contracting narcolepsy within eight months of the inoculation, compared with those who did not get the jab.
The working group says it is most likely that the vaccine increased the likelihood of falling ill with narcolepsy in conjunction with some other factor or factors.
It expects to confirm the preliminary findings within a few months.
Fifty-two Finnish children who were given the vaccine last winter subsequently came down with narcolepsy, which can be a debilitating lifelong condition. That is many times more than the annual average in recent years.
An increase was also reported in Sweden, but not so far in other countries where the vaccine was used.
"The trigger for narcolepsy remains unclear, which makes it difficult to evaluate the link to the vaccine," says Kari Välimäki, Permanent Secretary at the Minister of Social Affairs and Health.
The nation's highest-ranking physician, Risto Pelkonen, told the newspaper Ilta-Sanomat that the families of these narcolepsy patients should be reimbursed by the state.
