Pfizer says Covid-19 pill near 90% effective against Omicron
Pfizer on Tuesday said final analysis of its antiviral Covid-19 pill still showed near 90 per cent efficacy in preventing hospitalisations and deaths in high-risk patients, and recent lab data suggests the drug retains its effectiveness against the fast spreading Omicron variant of the coronavirus.
The US drugmaker last month said the oral medicine was around 89 per cent effective in preventing hospitalisations or deaths when compared to placebo based on interim results in around 1,200 people. The data disclosed on Tuesday includes an additional 1,000 people.
Nobody in the trial who received the Pfizer treatment died, compared with 12 deaths among placebo recipients.
