NEW YORK >> Fully vaccinated Americans can gather with other vaccinated people indoors without wearing a mask or social distancing, according to long-awaited guidance from federal health officials.

The recommendations also say that vaccinated people can come together in the same way — in a single household — with people considered at low-risk for severe disease, such as in the case of vaccinated grandparents visiting healthy children and grandchildren.

The Centers for Disease Control and Prevention announced the guidance today.

The guidance is designed to address a growing demand, as more adults have been getting vaccinated and wondering if it gives them greater freedom to visit family members, travel, or do other things like they did before the COVID-19 pandemic swept the world last year.

“With more and more people vaccinated each day, we are starting to turn a corner,” said CDC Director Dr. Rochelle Walensky.

During a press briefing today, she called the guidance a “first step” toward restoring normalcy in how people come together. She said more activities would be ok’d for vaccinated individuals once caseloads and deaths decline, more Americans are vaccinated, and as more science emerges on the ability of those who have been vaccinated to get and spread the virus.

The CDC is continuing to recommend that fully vaccinated people still wear well-fitted masks, avoid large gatherings, and physically distance themselves from others when out in public. The CDC also advised vaccinated people to get tested if they develop symptoms that could be related to COVID-19.

Officials say a person is considered fully vaccinated two weeks after receiving the last required dose of vaccine. About 31 million Americans — or only about 9% of the U.S. population — have been fully vaccinated with a federally authorized COVID-19 vaccine so far, according to the CDC.

Authorized vaccine doses first became available in December, and they were products that required two doses spaced weeks apart. But since January, a small but growing number of Americans have been fully vaccinated, and have been asking questions like: Do I still have to wear a mask? Can I go to a bar now? Can I finally see my grandchildren?

The guidance was “welcome news to a nation that is understandably tired of the pandemic and longs to safely resume normal activities,” said Dr. Richard Besser, president and CEO of the Robert Wood Johnson Foundation and a former acting director of the CDC.

“I hope that this new guidance provides the momentum for everyone to get vaccinated when they can and gives states the patience to follow the public health roadmap needed to reopen their economies and communities safely,” said Besser, in a statement.

But Dr. Leana Wen called the guidance “far too cautious.”

The CDC did not change its recommendations on travel, which discourages unnecessary travel and calls for getting tested within a few days of the trip. That could seem confusing to vaccinated people hoping to visit family across the country or abroad.

The new guidance also says nothing about going to restaurants or other places, even though governors are lifting restrictions on businesses, said Wen, an emergency physician and public health professor at George Washington University who was formerly Baltimore’s health commissioner.

“The CDC is missing a major opportunity to tie vaccination status with reopening guidance. By coming out with such limited guidance, they are missing the window to influence state and national policy,” Wen said, in an email.

The CDC guidance did not speak to people who may have gained some level of immunity from being infected, and recovering from, the coronavirus.
