New Delhi, Mar 30 (PTI) A new research provided evidence of viral resistance to Paxlovid among SARS-CoV-2 variants currently circulating globally, indicating that this stand-alone drug could soon become less effective in treating COVID-19 infections.

The research showed that simple single amino acid changes in SARS-CoV-2 main protease could severely undermine efficacy of these antiviral drugs.

The study, conducted by the Midwest Antiviral Drug Discovery (AViDD) Center, US, is published in the journal Science Advances.
