U.S. health authorities said on Monday that fully vaccinated people can gather in small groups with those at low-risk for COVID-19 without masks. 

The U.S. Centers for Disease Control(CDC) presented guidelines for what people can do once they are fully vaccinated.

The CDC defined "fully vaccinated" as people who have received all of their COVID-19 vaccine doses and waited two weeks to build their full immune response. 

The new CDC guidelines advised that fully vaccinated people can safely gather indoors, unmasked and without distancing, with other fully vaccinated people or with unvaccinated people from one other household who have a low risk of severe disease. 

However, the CDC said that fully vaccinated people should still wear masks in public, distance from others and keep up COVID health precautions.
