On June 3rd, U.S. Senator Jeff Merkley announced that he had a “rebound” Covid-19 infection after taking Pfizer’s antiviral, Paxlovid. In a statement he posted on Twitter, Merkley wrote: “After recovering and feeling better, some COVID symptoms have returned I have again tested positive. This is occurring in a modest percent of folks who used Paxlovid and is called ‘COVID-19 rebound.”
