Narcoleptics exposed to A/H1N1 vaccine
Adjuvanted (ASO3) A/H1N1 pandemic vaccine
Biological: A/H1N1 vaccine
Verify if exposure to Arepanrix vaccine increase risk of developing narcolepsy in 16 weeks post-vaccination.
Other Name: Arepanrix vaccine
Narcoleptics unexposed to A/H1N1 vaccine
Narcoleptic subjects who were unexposed (non-vaccinated or vaccinated after onset) to adjuvanted (ASO3) A/H1N1 pandemic vaccine.
- Incidence of Narcolepsy Among Narcoleptic Subjects Exposed or Unexposed to Vaccine [ Time Frame: Narcolepsy onset during the 16-week post-vaccination period. ]Incidence rates will be computed by comparing narcolepsy incidence rates in exposed and non-exposed subjects. Comparison of narcolepsy incidence rates in the period prior to vaccine administration and pseudo-vaccine administration will be used to test the comparability of exposed and non-exposed group.
