Federal health officials released guidance Monday that gives fully vaccinated Americans more freedom to socialize and pursue routine activities, providing a pandemic-weary nation a first glimpse of what a new normal may look like in the months ahead.

The Centers for Disease Control and Prevention said people who are two weeks past their final shot face little risk if they visit indoors with unvaccinated members of a single household at low risk of severe disease, without wearing masks or distancing. That would free many vaccinated grandparents who live near their unvaccinated children and grandchildren to gather for the first time in a year. The guidelines continue to discourage long-distance travel, however.
