The most important thing you can do to ensure safe interactions is to become vaccinated yourself. Many students and employees have already received at least one dose. Vaccination provides robust protection against COVID-19.
Because people who are not fully vaccinated do not have this protection, if you are not yet fully vaccinated, you should continue to wear face coverings indoors (unless working alone in a closed office) and outdoors where physical distancing cannot be maintained.
Everyone should continue to maintain at least 6 feet of physical distancing indoors, regardless of vaccination status.
