U.S. health officials are now recommending that people who are fully vaccinated against the coronavirus do not have to go into a 14-day quarantine after exposure to an infected person.
The Centers for Disease Control and Prevention quietly posted the updated guidance this week.
It says vaccinated people may skip quarantine if they are asymptomatic, and if their contact with an infected person came at least two weeks after receipt of the final dose in the two-shot vaccination series and within three months of receipt of that last dose.
The recommendation is similar to what the CDC has said about people who developed immunity after being infected with COVID.
Other recommendations to prevent coronavirus transmission remain in place for fully vaccinated people as well. The measures include wearing masks, social distancing and avoiding crowds and poorly ventilated spaces.
The guidance says the risk that fully vaccinated people could spread the coronavirus to others is “still uncertain.”
However, “vaccination has been demonstrated to prevent symptomatic Covid-19; symptomatic and pre-symptomatic transmission is thought to have a greater role in transmission than purely asymptomatic transmission,” according to the CDC.
