Pfizer confirms COVID pill's results, potency versus omicron

Pfizer said Tuesday that its experimental pill to treat Covid-19 appears effective against the omicron variant.

The company also said full results of its 2,250-person study confirmed the pill's promising early results against the virus: The drug reduced combined hospitalisations and deaths by about 89% among high-risk adults when taken shortly after initial Covid-19 symptoms.

Separate laboratory testing shows the drug retains its potency against the omicron variant, the company announced, as many experts had predicted. Pfizer tested the antiviral drug against a man-made version of a key protein that omicron uses to reproduce itself. (AP)
