Pfizer CEO tests positive for COVID-19, has mild symptoms
The top executive at Pfizer, a leading producer of COVID-19 vaccines and medicines, has tested positive for the virus and says he is experiencing very mild symptoms.
Chairman and CEO Albert Bourla said Monday that he began treatment with Pfizer’s Paxlovid pill and is isolating while he recovers.
Bourla has received four shots of Comirnaty, the COVID-19 vaccine developed by the New York drugmaker along with BioNTech. He said in a brief statement issued by the company that he is confident of a quick recovery.
More than 128 million people in the United States have become fully vaccinated with Pfizer’s two-shot vaccine since it became available in December 2020, and almost 61 million have received an initial booster shot, according to the Centers for Disease Control and Prevention.
Determining which version of the coronavirus should be used to make COVID-19 vaccines and boosters is an exercise in educated guesswork.
Scientists say the vaccine still offers solid protection against hospitalization and serious illness. But the evolving virus has made it tougher for vaccines to prevent infections.
Pfizer and another vaccine maker, Moderna, are updating their shots to provide protection against newer versions of the virus for a fall booster campaign.
Paxlovid has been shown to be extremely effective at warding off serious illness in high-risk patients if it is administered shortly after symptoms start. However, it doesn’t seem to help people who aren’t at high risk of serious disease.
Comirnaty and Paxlovid are the top-selling COVID-19 vaccine and treatment on the market. Combined, they brought in nearly $17 billion in sales for Pfizer during the recently completed second quarter.
