Albert Bourla, CEO of COVID-19 vaccine maker Pfizer, has tested positive for the coronavirus but is showing no symptoms, he said over the weekend.

"I have tested positive for COVID. I'm feeling well & symptom free. I've not had the new bivalent booster yet, as I was following CDC guidelines to wait 3 months since my previous COVID case which was back in mid-August. While we've made great progress, the virus is still with us," he said on Twitter on Saturday.

Bourla has received four rounds of the Pfizer vaccine. He first tested positive for COVID on Aug. 15, Reuters reported. At the time, Bourla, 60, said he was isolating and had started a course of the company's oral COVID-19 antiviral treatment, Paxlovid.

The CDC says people who get COVID should delay getting the booster because the infection provides some immunity. You may "consider delaying your vaccine by 3 months from when your symptoms started or, if you had no symptoms, when you received a positive test," the CDC says.
