The CDC issued coronavirus-related guidelines for how fully vaccinated people can safely interact with others. Under the guidelines, people who have been fully vaccinated can visit with others indoors without wearing masks or staying 6 feet apart, so long as everyone has been vaccinated or those who have not are at low risk for severe disease. The guidelines also suggest that people continue avoiding medium- and large-sized in-person gatherings and wear masks while in public or while visiting with unvaccinated people from multiple households.
More context: Under the guidance, a person is considered “fully vaccinated” two weeks after receiving the last required dose of a vaccine
