Multiple Sclerosis Clinical Trial
Official title:
An Observational Retrospective Database Analysis to Estimate the Risk of Multiple Sclerosis Following Vaccination With Arepanrix™ in Manitoba, Canada
The purpose of this database study is to assess if Arepanrix™ vaccination during the 2009 pandemic was associated with an increased risk of multiple sclerosis (MS) in Manitoba, Canada.
This observational, retrospective, propensity-score matched cohort study using the Manitoba
Immunization Monitoring System (MIMS) and the hospital, physician, and prescription claims
databases of the Manitoba Health (MH) Database System will assess if Arepanrix™ vaccination
during the 2009 pandemic was associated with an increased risk of multiple sclerosis (MS)
and other demyelinating conditions not ultimately leading to a multiple sclerosis diagnosis
in Manitoba, Canada.
The data will be collected form the following linked databases:
- Manitoba Health (MH) administrative databases
- Manitoba Immunization Monitoring System (MIMS)
- Manitoba Health Population Registry (MHPR)
- Drug Program Information Network (DPIN)
- Hospital Abstract Database
- The Medical Services database
