U.S. government researchers are planning studies of how often and why coronavirus levels rebound in some Covid patients who have completed a five-day course of treatment with Pfizer Inc.’s Paxlovid.

The World Health Organization said Friday it "strongly recommended" Pfizer's Covid-19 antiviral pill Paxlovid for patients with milder forms of the disease who were still at a high risk of hospitalisation.

A former Pfizer contractor-turned-whistleblower said the Big Pharma company forged informed consent signatures and falsified and fabricated clinical trial data for its Wuhan coronavirus (COVID-19) mRNA vaccine.

Pfizer projects it will generate record-high revenue in 2022, saying Tuesday it expects to sell $32 billion of its Covid-19 shots and $22 billion of its antiviral coronavirus treatment pill Paxlovid this year.

Bourla says boosters against coronavirus will remain necessary, but anti-COVID pill ‘changes everything’

Last week, the FDA authorized two much-hyped antiviral treatments for COVID (just in time for Christmas): Merck's Molnupiravir and Pfizer's Paxlovid.

The US government will pay drugmaker Pfizer $5.29 billion for 10 million treatment courses of its potential COVID-19 treatment if regulators authorize it, the nation’s largest purchase agreement yet for a coronavirus therapy.
