how are covid monoclonal antibodies made

Sign up for The Conversations newsletter.]. For example, as SARS-CoV-2 mutated, variants of concern such as omicron escaped the antibodies that were very effective against COVID early in the pandemic. The Food and Drug Administration (FDA), European Medicines Agency (EMA), and other regulatory agencies around the world are evaluating monoclonal antibodies for use as a therapy to treat COVID-19 . If youve been prescribed a drug that interacts with Paxlovid, your doctor may recommend another antiviral drug or a monoclonal antibody instead. Monoclonal antibodies are one of most powerful types of medicine. This provides a therapeutic candidate for fighting against new mutations of the COVID-19 virus, Chen says. A new form of monoclonal antibody therapeutic to treat the disease is described in a new study, which graces the cover of Plant Biology Journal.
