As vaccines are now available and some of our population has been vaccinated and others will be vaccinated soon, the issue of requiring people to be vaccinated or requiring people to show or provide a vaccination certificate will be front and center. On December 11, 2020, my office posted an Advisory on vaccinations. I thought it was time to review that Advisory and, if necessary, update it. I have done that review and made minor changes. The updated Advisory can be found here: Advisory from the IPC on questions regarding vaccines for organizations, employers and health trustees.
