While Participating

As a participant you would complete online surveys and go to a lab location near you for blood work every 6 months over the study period:

• Surveys: All participants will complete online surveys at approximately the same time as the blood collections. You will access each survey through the Participant Portal. We recommend against using a smart phone for the survey as it will be difficult to see all the questions properly. You can take a break from the survey and come back to it later. We will send you a reminder if you do not finish the survey.
• The first set of surveys will be longer and will take approximately 35-45 minutes to complete
• The follow-up surveys will be a shorter and will take about 30 minutes to complete
• Bloodwork:
  • Please consult the “Blood Collection Calculator” in the Participant Portal to find the exact blood collection target dates for you.
  • For vaccinated individuals, the blood samples should be performed at the time of enrollment, and then at 6-month intervals after the first vaccine dose. For non-vaccinated individuals, the blood sample should be at 6-month intervals after enrollment.
  • Examples:
    • If you enrolled in the study in January 2021 and were vaccinated Feb. 15, 2021, you would have provided an enrollment sample in January/21, a 6-month sample (measured from the first vaccine date + 6 months) on Aug. 14/21, a 12-month sample on Feb. 15/22, and can provide an 18-month sample on Aug. 14/22.
    • If you enrolled in the study on July 15/21, have not been vaccinated, and forgot to provide any blood samples so far, you can provide your first sample today, skip your 6-month sample (as it has passed), provide your 12-month sample (measured from the date of enrollment + 12 months) on July 15, your 18-month sample on Jan. 11/23, and a final sample at study end in March/23.
    • If you enrolled in the study today and were vaccinated Feb. 15, 2021, you would have missed the 6-month and 12-month samples, but that is not a problem—you can provide the enrollment sample today, and the next sample at 18-months on Aug. 14/22, and a final sample at the end of the study in March/23.
• You can retrieve a requisition to obtain your blood work in the user portal. You will get information on how to access your user portal when you enrol in the study. Study blood testing locations per province are listed on our blood testing page. If there are no blood collection services in your region, we will offer you a self-blood collection option (“dried blood spot” – see FAQ’s).

• The initial consent form included consent for 3 blood collections. Please fill out the “Consent Extension Form” (in the Participant Portal) for further study participation.

Please contact your provincial study coordinator should you require study materials in French.

• What is SARS-CoV-2 serology test?
