The Finnish National Institute for Health (THL) proposed suspending vaccinations for H1N1 swine flu, due to suspected links to increased narcolepsy in children and adolescents, the body announced this week.
Six cases of narcolepsy, a chronic disorder causing excessive daytime sleepiness and extreme fatigue, have been reported after patients had been receiving the Pandemrix vaccine.
Six cases of narcolepsy is consistent with annual averages, reports THL, but all of these patients were affected after being vaccinated, and there are nine additional cases that have not yet been confirmed.
The precautionary measure will take effect until the actual cause of the current health issue can be established. Preliminary results of the investigation will take several months to be known, says the THL.
