The COVID-19 Occupational Risks, Seroprevalence and Immunity among Paramedics (CORSIP) project seeks to identify COVID19-related occupational risks to paramedics and develop recommendations to protect paramedic health


Timing of 2nd blood sample
  • If you are vaccinated: Please provide your 2nd blood sample 6 months after the date of your first vaccine dose.
  • If you were not vaccinated, provide your 2nd sample 6 months after the 1st sample.

New result reporting for all participants – We are retesting all samples to provide information to vaccinated participants of whether there is evidence of “N” antibodies, indicating a previous COVID-19 infection. These results will typically follow the initial result by 1-2 months.

Are you living in a remote area and unable to get your blood drawn for the study at one of the designated lab locations?

  • Dried blood spot collection kits are now available for home collection! We will mail you the self-collection kits along with instructions and pre-paid envelopes to return your blood samples to us for antibody testing. The consent form and further details are available upon request. If you would like to arrange for a kit please email your provincial study coordinator.

Have you been infected with COVID-19 after being vaccinated?
If so, we are very interested in hearing from you. If you have a confirmed COVID-19 infection after vaccination please email your provincial study coordinator.

CORSIP is a study of paramedics in British Columbia and Ontario. It aims to recruit 5000 paramedics who will complete surveys and collect blood samples three times over one year.

  • Your blood samples will help us identify how many paramedics have developed antibodies to the virus that causes COVID-19 and how long these antibodies last. These antibodies may be from infection or immunization. Subsequent samples will show if these antibodies are still present. You are eligible whether or not you have been vaccinated, however if you have not been vaccinated please provide your first blood sample prior to vaccination. We will share your personal lab results with you through this study portal!
  • Your survey responses will help us assess the occupational risk of working as a paramedic during the COVID-19 pandemic. We will further investigate workplace factors that increase or decrease paramedics' risk of developing COVID-19.

This project is funded by the COVID-19 Immunity Task Force, as part of a national effort to by the Government of Canada to track spread of the virus in priority populations in Canada.

The study is currently recruiting and we need as many paramedics as possible!
Help us reach our goal of 5,000!
