WASHINGTON - Pfizer said Tuesday that clinical trials confirmed its Covid pill, a new type of antiviral treatment that should withstand the mutations seen with Omicron, drastically reduced hospitalizations and deaths among at-risk people by almost 90 percent.
A preliminary study shows the Omicron variant is 'highly transmissible' and may better evade vaccines.

The positivity rate now stands at 34.9 percent.
