March 11, 2021 When the U.S. Centers for Disease Control and Prevention (CDC) issued new guidelines this week that stated fully vaccinated individuals can gather indoors without a mask, people may have wondered whether they can leave their masks at home when they go to work. Although the guidance is relevant to people in social situations, it does not apply to the workplace, where employees will still need to follow mask and social distancing rules set for their facility. The new guidelines do give fully vaccinated people the green light to gather indoors with a small group of unvaccinated people from one other household without masks. However, it recommends people wear masks in public and while gathering with unvaccinated people from several households. Fully vaccinated people should continue to avoid medium- or large-sized gatherings and wear masks when around those at an increased risk of severe illness or death from COVID-19.
