While Participating

As a participant you would complete online surveys and go to a lab location near you for blood work three times over a one-year period:

  • Surveys: All participants will complete 3 online surveys. You will access each survey through the User Portal (we will send you a link). 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 second survey will be a shorter follow-up questionnaire after 6 months and will take about 30 minutes to complete
  • The third and final survey will also be a shorter follow-up questionnaire after 12 months of involvement and will take about 30 minutes to complete
  • Bloodwork: All participants will provide blood work at three times throughout the study. The first is at the beginning. For vaccinated individuals, the second blood sample should be 6 months after the first vaccine dose. For non-vaccinated individuals, the second blood sample should be 6 months after the first sample. The final sample will be in early 2022. 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. Currently not all of our lab procedures are live; you will receive an email notifying you when there are updates regarding blood testing locations. If we are unable to secure blood collection services in your region, we will offer you a self-blood collection option (“dried blood spot” – see FAQ’s).
