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!

All participants, please take a few minutes to log in to the study portal to update your vaccine and infection status:

COVID19 vaccination status and COVID-19 infection status are found on the main questionnaire, Questions 19, 34 – 37. Once updated please scroll to the bottom of the page to “submit” your changes. Thank you for helping us to ensure that your study information is up to date!

ALBERTA Participants

Alberta Precision Labs is now available for study blood collection. Please download your lab requisition from the study portal and complete your first blood collection as soon as possible. Thank you for your patience. Edmonton participants: DynaLife will be coming soon!

BLOOD Updates

Only 50% of our study participants have gone for their first blood collection

We understand if you’ve been unable to make it to the lab and would really like to help. Please contact your provincial study coordinator for further assistance or let us know if you are unable to give a sample.

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 have not provided a 1st sample yet and this date is very close, then feel free to skip the 1st sample). 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.

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!
