President Joe Biden has once again tested positive for COVID-19, experiencing a rebound case after completing a course of the antiviral drug Paxlovid. This phenomenon, known as “Paxlovid rebound,” has been reported in a small percentage of patients who have taken the medication.
Paxlovid is an oral antiviral drug authorized by the FDA for the treatment of mild-to-moderate COVID-19 in high-risk individuals. The drug has been shown to be highly effective in reducing the risk of hospitalization and death, with clinical trials reporting an 89% reduction in these outcomes. However, some patients have reported a resurgence of COVID-19 symptoms or a positive test result after initially testing negative following Paxlovid treatment.
The CDC defines Paxlovid rebound as when a patient, after receiving a full five-day course of Paxlovid, either has a reemergence of COVID symptoms or tests positive again after a previous negative test. Experts explain that this may be due to insufficient exposure to the drug, as Paxlovid’s effects might not persist long enough to completely eradicate the infection, allowing the virus to replicate temporarily after treatment cessation.
Importantly, the rebound cases have been predominantly mild, with less than 1% of patients requiring hospitalization post-rebound. Infectious disease specialists emphasize that the benefits of Paxlovid in preventing severe illness outweigh the potential drawbacks of the rebound effect. They advise patients experiencing a rebound to follow isolation protocols until testing negative again.
President Biden’s case is a high-profile example of Paxlovid rebound, with the president testing positive again after initially completing a course of the drug and testing negative. Biden’s chief medical advisor, Dr. Anthony Fauci, has also experienced a similar rebound case and was prescribed a second round of Paxlovid.

While the rebound phenomenon has raised questions about the drug’s efficacy, experts maintain that Paxlovid remains a valuable tool in the fight against COVID-19, particularly for high-risk individuals. The mild nature of the rebound cases and the drug’s proven effectiveness in reducing severe outcomes make it a recommended course of action for eligible patients.
As the COVID-19 pandemic continues to evolve, the scientific community remains committed to understanding the complexities of Paxlovid rebound and exploring potential solutions to mitigate this issue. Patients and healthcare providers must weigh the risks and benefits of Paxlovid treatment, while remaining vigilant and following isolation guidelines in the event of a rebound case.
