According to the Center for Disease Control, people who have been fully vaccinated can gather with with small groups of people from other households without masks or social distancing, even if the other people are not vaccinated.

The CDC says a person is considered vaccinated two weeks after they receive their final shot of the vaccine.

"This guidance represents a first step toward returning to everyday activities," the CDC said in a media statement.

"Fully vaccinated grandparents can visit indoors with their unvaccinated healthy daughter and her healthy children without wearing masks or physical distancing, provided none of the unvaccinated family members are at risk of severe COVID-19,” said the statement.

According to the CDC, more than 90 million vaccines have been administered - equating to 10% of the US population being full vaccinated.
