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.

Yksityiskohtainen kuvaus
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

Exposed to Arepanrix™ Cohort
All individuals with Manitoba Immunization Monitoring System (MIMS) record of H1N1 (Arepanrix™) and/or seasonal influenza vaccination during the influenza season 2009/2010 (15 September 2009 to 15 March 2010).
|
Demographic characteristics such as age, sex, area of residence, socio-economic status; medical history such as comorbidities, immune status, vaccine indication, receipt of other vaccines or medications and frequency of healthcare contacts, as well as information on pregnancy status and pre-existing conditions will be collected..
