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!

Results: Results typically take 4-12 weeks after collection. If you want to confirm sample receipt, check the Participant Portal for a collection date (samples can take to 2-4 weeks to arrive).

The study will end in March 2023. Please consider signing the additional consent form in the Participant Portal if you have not already.

When should I complete the study blood tests? Use the Blood Sample Time-Point Calculator in the Participant Portal to determine when you should provide samples.

**Please also provide a sample 6-8 weeks after receiving a bivalent Omicron vaccine.** We will be providing participants with Omicron-specific immune levels for these samples.

Questionnaires: Please fill out your questionnaires! There is one for each blood collection (every 6 months).

Please update your vaccine status (including for boosters) and any COVID-19 infections in your study Participant Portal. This data is very important to the study results and if it remains incomplete you may be contacted by a study team member to confirm it. Thank you for helping us keep your data accurate.

Have a question? Contact 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 every 6 months.

  • 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. 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.
