(CNN) -- The Centers for Disease Control and Prevention say recent findings show some people who took Paxlovid had a reappearance of COVID-19 symptoms.
The anti-viral drug made by Pfizer is to help treat COVID-19 symptoms.
They also say patients re-tested positive a few days later. The CDC says those who had a COVID rebound often had mild and brief illness.
The CDC still recommends Paxlovid for early-stage COVID-19 patients at high risk for severe disease.
