‘Paxlovid rebound’ is the name given to people who test positive for Covid again after completing a course of Paxlovid and testing negative. It’s not known how common this is, but researchers think this may happen because Paxlovid suppresses the virus before the body has had time to develop a natural immune response to it.
If you test positive after taking Paxlovid, speak to your physician for advice. You may be advised to isolate for a few days until you test negative.
