Americans who have been fully-vaccinated against COVID-19 are now able to meet each other indoors without face masks or following social distancing measures as health officials announce new coronavirus guidance.
The recommendations from the Centers for Disease Control and Prevention (CDC) also say that vaccinated people can come together in the same way with those considered to be at low risk for severe disease.
An example of this would be a grandparent whose vaccination had been complete would now be allowed to visit healthy children and grandchildren.
However, they are still being advised to continue to wear well-fitted masks, avoid large gatherings, and physically distance themselves from others when out in public.

The guidance has been published amid growing calls for clarity over what rules adults, who have received one vaccine dose, must follow.
About 30 million Americans – or around 9% of the US population – have been fully vaccinated with a federally authorised COVID-19 vaccine so far, according to the CDC.
Health officials say a person is considered to be “fully-vaccinated” two weeks after receiving their final required jab.
CDC director Dr Rochelle Walensky said in a statement: “We know that people want to get vaccinated so they can get back to doing the things they enjoy with the people they love.”
The public agency is continuing to recommend vaccinated people get tested if they develop symptoms that could be related to COVID-19.
According to Johns Hopkins University, the United States has recorded more than 29 million cases of coronavirus and 525,136 related deaths.
