Narcolepsy in association with pandemic influenza vaccination – a multi-country European epidemiological investigation
This report summarises the results from two epidemiological studies conducted by the Vaccine Adverse Event Surveillance and Communication (VAESCO) Consortium undertaken in eight European Union (EU)/European Economic Area (EEA) countries in order to investigate a possible association between an unexpected increase in narcolepsy cases following the use of influenza A(H1N1)pdm09 vaccines. Narcolepsy is an underdiagnosed disease of widely unknown etiology.
