Arexvy is not a live vaccine it is a recombinant subunit vaccine that does not contain any live virus. Recombinant vaccines are made by taking a small piece of DNA that codes for a specific protein (called an antigen) on the virus (in this case the respiratory syncytial virus [RSV]) and inserted into bacteria or yeast cells in a laboratory to manufacture the vaccine. The vaccine helps your body's immune system make proteins called antibodies against the virus. These antibodies will help prevent infection by attacking the virus if it ever infects your body.
