People vaccinated against COVID-19 can go without masks. The CDC Director made the announcement yesterday and cited three studies that show vaccines work. Dr. Rochelle Walensky said anyone who is fully vaccinated can participate in indoor and outdoor activities, large or small, without wearing a mask or physical distancing, except under certain circumstances. Fully vaccinated people will still need to wear masks in health-care settings, at businesses that mandate them or on public transportation. The CDC also advises that that people who are immune compromised should speak with their doctors before giving up their masks.
