Americans who have received the full COVID-19 vaccine can gather with vaccinated grandparents or friends indoors 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 the 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.
