(Reuters) -Pfizer Inc Chief Executive Officer Albert Bourla said on Saturday he had tested positive for COVID-19.
"I’m feeling well and symptom free," Bourla said in a statement.
Bourla, 60, back in August had contacted COVID and had started a course of the company's oral COVID-19 antiviral treatment, Paxlovid.
Paxlovid is an antiviral medication that is used to treat high-risk people, such as older patients.
Bourla has received four doses of the COVID vaccine developed by Pfizer (NYSE:PFE) and its German partner BioNTech.
The chief executive said he has not yet taken the new bivalent booster.
Developed by Moderna (NASDAQ:MRNA) and the team of Pfizer and BioNTech, the new so-called bivalent shots aim to tackle the BA.5 and BA.4 Omicron subvariants, which make up 84.8% and 1.8%, respectively, of all circulating variants in the United States, based on latest data.
"I’ve not had the new bivalent booster yet, as I was following CDC guidelines to wait three months since my previous COVID case which was back in mid-August," Bourla added.
In August, the FDA authorized Pfizer and Moderna's updated booster shots that target the dominant BA.4 and BA.5 Omicron subvariants.
A federal health agency said this week that over 25 million doses of the so-called bivalent shots had been sent out. That consisted of mostly the Pfizer/BioNTech vaccine, as production of the Moderna vaccine ramps up.
