COVID-19 Vaccine Certificates: Key Considerations for the Ontario Context
Many jurisdictions are developing and implementing COVID-19 vaccine certificates as falsification-proof, verifiable proof of immunization in secure digital or paper-based formats.
Vaccine certificates can be used to regulate entry into discretionary settings that pose a high risk for SARS-CoV-2 transmission (e.g., indoor dining, bars, gyms, cultural and sports events).
Vaccine certificates can also be used in non-discretionary settings (e.g., schools, universities, congregate settings, and workplaces), especially in settings that require mandatory vaccination.
On a short-term basis, vaccine certificates could enable the re-opening of high-risk settings sooner and/or at increased capacity. Vaccine certificates will be of particular importance to maintain economic and societal reopening if public health measures need to be reintroduced. Some jurisdictions are also implementing vaccine certificates with the goal of incentivizing COVID-19 vaccination.
On a longer-term basis, vaccine certificates can serve as a verifiable, secure, standardized, accessible and portable records of immunization.
There is currently no scientific evidence of the direct impact of COVID-19 vaccine certificates on SARS-CoV-2 transmission or population vaccination rates, and there are important ethical, legal, accessibility, and privacy considerations concerning their development and implementation.
