(CNN)People who have been fully vaccinated against coronavirus — right now that means with two doses of either the Pfizer/BioNTech or Moderna vaccine — can skip quarantine if they are exposed to someone infected with the virus, the US Centers for Disease Control and Prevention said Wednesday.
That doesn’t mean they should stop taking precautions, the CDC noted in updated guidance. It’s just not necessary for them to quarantine.”Fully vaccinated persons who meet criteria will no longer be required to quarantine following an exposure to someone with COVID-19,” the CDC said in updates to its web page with guidance on vaccination.
“Vaccinated persons with an exposure to someone with suspected or confirmed COVID-19 are not required to quarantine if they meet all of the following criteria,” the CDC added.
The criteria: They must be fully vaccinated — having had both shots with at least two weeks having passed since the second shot. That’s because it takes two weeks to build full immunity after the second dose of vaccine.
But the CDC says it’s not known how long protection lasts, so people who had their last shot three months ago or more should still quarantine if they are exposed. They also should quarantine if they show symptoms, the CDC said.
“This recommendation to waive quarantine for people with vaccine-derived immunity aligns with quarantine recommendations for those with natural immunity, which eases implementation,” the CDC said. The agency will update guidance as more is learned.
