Americans who have received the full COVID-19 vaccine can gather with vaccinated grandparents or friends without wearing masks or keeping their distance, according to new CDC guidance announced Monday, and those grandparents can visit with and hug family members that aren’t vaccinated as long as they don’t have underlying medical conditions that put them at high risk for COVID-19.

But getting the vaccine does not mean you should travel or gather in large groups, according to the CDC, which says vaccinated individuals should still stick to guidance.

The CDC says individuals who are fully vaccinated — meaning two weeks after they have received the second dose of the Pfizer or Moderna vaccines or the single dose Johnson & Johnson vaccine — can safely gather around friends or family who are also vaccinated indoors without masks or social distancing, as well as visit with friends or family from a single household who aren’t vaccinated but have a low risk of severe disease from COVID-19.

“If you and a friend or you and a family member are both vaccinated, you can have dinner together,” CDC Director Dr. Rochelle Walensky said, without wearing masks and without distancing. “You can visit your grandparents, if you have been vaccinated and they have been too,” she said in a White House briefing.

In a group where some individuals are vaccinated and some aren’t, Walensky said the recommendations are more complicated. CDC says it is low risk for vaccinated individuals to gather with unvaccinated individuals indoors without masks and social distancing, as long as the people who aren’t vaccinated are at low risk of severe disease and no one in their household is at high risk.

“Here’s an example: If grandparents have been vaccinated, they can visit their daughter and her family, even if they have not been vaccinated, so long as the daughter and her family are not at risk for severe disease,” she said.
