Once you’re vaccinated, the Centers for Disease Control and Prevention have officially OK’d having friends over for dinner if they’re vaccinated, too. The guidelines also say that once vaccinated, you can have a mask-less, indoor hangout even if your guests aren’t vaccinated, as long as you’re gathering with people from a single household, and no one in that household (or anyone they live with) has an increased risk for severe illness from COVID-19. In other words, even if you’re weeks away from that first shot, you needn’t necessarily wait to break bread with your vaccinated parents or grandparents.
