Frequently Asked Questions
CANVAS-COVID Study FAQ
The purpose of the study is to find out how often health events occur after a COVID-19 vaccine.
When you sign up we will ask you for some minimal contact information (e.g. first name, email address and telephone number), the date of your COVID-19 vaccination and vaccine product.
After registering, you will be sent 3 surveys that will ask some personal information (age in years, sex and gender), information on any past confirmed COVID-19 illness and any health events since your COVID-19 vaccine. We want to know about any health problems which prevent you from going about your regular daily activities and/or cause you to seek medical care.
- Survey 1: 8 days AFTER you get the first COVID-19 vaccine
- Survey 2: 8 days AFTER you get the second COVID-19 vaccine (if given a second dose)
- Survey 3: 6 months AFTER you get the second COVID-19 vaccine
If you report a health problem which made you visit a doctor or nurse, we may call you to find out more about the symptoms of the health problem.
There is no direct benefit if you decide to take part in this study, but the information that will be collected might help us better understand the safety of the COVID-19 vaccine.
If you haven’t received the COVID-19 vaccine, you can participate in the study in our non-vaccinated group. When enrolling, please select “no” to the question “Have you received a COVID-19 vaccine?” and the link will take you to the non-vaccinated survey.
We aim to enrol 300,000 participants per vaccine per participating region.
Participant confidentiality and privacy is of the utmost importance to the study team.
If you decide to participate your email address, phone number and your first name will be kept on the REDCap secure server housed at BC Children’s Hospital Research Institute in Vancouver. Only study staff will have access to your email address, phone number and first name. Survey responses (without contact information) will be downloaded for analysis by the study team and by provincial public health. All data will be deleted from the REDCap database at the end of the study.
No records which identify you will leave the researchers’ offices unless required by law.
You will not be identified by name in any study reports.
The most common cause for the survey link not working is anti-virus software (e.g. McAfee). You may need to temporarily turn off your anti-virus settings while on the survey website. You can also try using a different device or different browser.
Vaccinated participants will need to register within 1 week of receiving their vaccine.
Yes, you may receive a COVID-19 vaccine at any time that it’s available to you.
No. The control survey will confirm that you have not received the vaccine. If you have received it, the survey will end.
Yes, you may join the vaccine safety survey after you have been vaccinated.
No, study participation will not influence when the vaccine is available to you.
This study is primarily tracking adverse events that resulted in participants seeking medical care.
The control survey is tracking health events occurring in the community. If similar rates of certain health events are happening in the control group and vaccinated group, it is likely that the vaccines are not causing that health event.
This survey is not mandatory; you do not have to enroll if you do not want to.
