TAMPA (WFLA) – People who have been fully vaccinated against COVID-19 do not need to quarantine if they are exposed to the coronavirus, the Centers for Disease Control and Prevention said Wednesday in updated guidance on its website.

In the updated guidance, the CDC said quarantining is not necessary for fully vaccinated people within three months of having received their last doses as long as they do not develop any symptoms. “Fully vaccinated” means that at least two weeks have passed since a person has received the second dose of a two-dose vaccine or one dose of a single-dose vaccine.

Other recommendations remain in place for fully vaccinated people. They 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.
