As of my last update, there was no study indicating that Paxlovid COVID pills have no benefit for adults aged 40-65. Paxlovid is an antiviral medication developed by Pfizer to treat COVID-19 in adults and certain pediatric populations. Clinical trials and research were still ongoing to assess its efficacy and safety for various age groups and conditions.
However, it's essential to note that medical research is continually evolving, and new data may have emerged since my last update. S. Food and Drug Administration (FDA), or other relevant health authorities for the most up-to-date information on Paxlovid and its efficacy for different age groups.
