The new paper describes the results of a COVID-19 drug clinical trial.

Pfizer’s COVID-19 drug did not work for many vaccinated people, according to a new paper from the company’s scientists.

There was not a statistically significant difference between Paxlovid and placebo recipients in terms of time to alleviation of symptoms, the scientists reported in the new paper.

The paper, published by the New England Journal of Medicine, describes the results of a company-funded phase 2-3 trial of the drug, which is also known as nirmatrelvir.
