Pfizer CEO Albert Bourla says he tested positive for COVID-19, has mild symptoms

Pfizer Chairman and CEO Albert Bourla on Monday said that has tested positive for COVID-19 and is isolating after experiencing mild symptoms.

Bourla, who heads the company that helped to create the widely used Pfizer-BioNTech coronavirus vaccine, announced the diagnosis on Twitter and shared some details of his treatment.

"I would like to let you know that I have tested positive for #COVID19," the 60-year-old CEO wrote. "I am thankful to have received four doses of the Pfizer-BioNTech vaccine, and I am feeling well while experiencing very mild symptoms. I am isolating and have started a course of Paxlovid."

Bourla wrote that while Paxlovid is not approved, the U.S. Food and Drug Administration (FDA) authorized it for emergency use to treat mild-to-moderate COVID-19 in high-risk patients ages 12 and older who weigh at least 88 pounds with positive results of direct SARS-CoV-2 viral testing. He included a link to safety information in his post.
