People vaccinated against the coronavirus in the U.S. can now gather in small groups indoors without restrictions a U.S. health agency said. The U.S. Centers for Disease Control and Prevention (CDC) made the announcement on Monday. The CDC said that small vaccinated groups could gather indoors without face coverings. It also advised that vaccinated people can meet with healthy people from a single home who are unvaccinated and at low risk for severe problems related to the virus. The guidance means that grandparents who have been vaccinated can meet with their healthy, unvaccinated grandchildren. Many vaccinated adults had been asking whether it is safe for vaccinated older people to meet with unvaccinated family members. The CDC answered that question with its recommendation.
