Pfizer's chief executive has tested positive for COVID-19 for the second time in two months.

Albert Bourla, the head of the company that created one of the most widely used coronavirus vaccines, said he was "feeling well and symptom free".

Mr Bourla, 60, contacted COVID back in August and had started a course of the company's oral COVID-19 antiviral treatment, Paxlovid.

Paxlovid is an antiviral medication used to treat high-risk people, such as older patients.
