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


We are still welcoming new participants, even if you have been vaccinated!

There is a new location in the User Portal to record your vaccine and COVID-19 infection status. Please update these questions now and if you get vaccinated or become infected with COVID-19:

Timing of Blood Samples

Vaccinated participants:  It is important for every vaccinated participant to provide a blood sample 6 months after the first vaccine dose. If you have not provided a 1st sample yet and this date is very close, then wait until this date (otherwise provide your 1st sample now, and the 2nd at the 6-month point). If you have already provided a sample, please provide your 2nd sample 6 months after the first vaccine dose.

Unvaccinated participants:  If you have not yet provided a sample please do so now. The 2nd sample should be provided 6 months after the 1st sample. If you get vaccinated at any time, consider yourself a “vaccinated participant”.

Timing of Questionnaires

Please fill out a questionnaire at the same time that you provide a blood sample. For example, when you provide your 2nd blood sample you should fill out the 2nd questionnaire.

Dried blood spot collection kits are still available for home collection! Please contact your provincial study coordinator if you need a kit.

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 Canada. 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!
