EYECARE: Coronavirus BRIEFING: Crisis Response Tactics Paxlovid Doesn't Prevent Infection in Households, Pfizer Says By Staff Monday, May 2, 2022 8:02 AM Paxlovid works as a treatment for COVID-19 but not as a preventive measure, particularly if you've been exposed to the coronavirus through a household member who is infected, according to a new announcement from Pfizer.In a clinical trial, the oral antiviral tablets were tested for post-exposure prophylactic use, or tested for how well they prevented a coronavirus infection in people exposed to the virus. Paxlovid somewhat reduced the risk of infection, but the results weren't statistically significant."We designed the clinical development program for Paxlovid to be comprehensive and ambitious with the aim of being able to help combat COVID-19 in a very broad population of patients," Albert Bourla, PhD, Pfizer's chairman and CEO, said in the announcement."While we are disappointed in the outcome of this particular study, these results do not impact the strong efficacy and safety data we've observed in our earlier trial for the treatment of COVID-19 patients at high risk of developing severe illness," he said.
