Thank you CORSIP study participants!
We are incredibly grateful for the time participants have donated to our study, from which we have acquired valuable information.
The CORSIP study will be ending in early 2023,
however we have one final opportunity for participants to provide a blood sample and fill out a *short* questionnaire.
If you have not yet provided all of the samples and questionnaires for the study, please disregard all previous reminders and
provide one final sample and fill out one final questionnaire between December 15, 2022 and January 30, 2023.
If you have provided all the samples and questionnaires of the study thus far and
would be willing to provide an optional final sample and questionnaire, we would welcome your participation as well!
This final questionnaire will take around 15 minutes to complete and is much shorter than the previous questionnaires.
Participants, please update your vaccination and COVID-19 infection information on the Participant Portal
For those of you who have received a bivalent vaccine, please consider providing an extra optional sample 6-8 weeks after the vaccine.
Commercial and hospital lab locations are listed per province on the study website Blood Testing page
and requisitions are available for download in the Participant Portal
Mobile Phlebotomy Clinics will be available in January 2023 in British Columbia and Alberta, with specific dates to come.
Please note that samples cannot be accepted after January 30, 2023. This deadline will ensure that we can process and analyze all samples before study end.
Please consider signing the additional consent form in the Participant Portal if you have not already.
We are still welcoming new participants until the end of January 2023.
