Last week, the Centers for Disease Control and Prevention changed its guidance. Now, fully vaccinated people can avoid quarantine after a COVID-19 exposure if they meet certain criteria.
According to the CDC, the quarantine exception can happen if the person is fully vaccinated (had both doses in a two-shot vaccine series), had their final dose at least two weeks prior to exposure, but no longer than 3 months prior to exposure, and does not have symptoms.
So, why did this change happen?
THE QUESTION
Does the guidance change mean researchers have proven you can't spread COVID-19 if you're vaccinated?
THE ANSWER
No. There's still not enough research to prove the vaccines prevent transmission of the virus. More practical reasons drove the change in guidance.
