Is Arexvy a live vaccine?
Arexvy is not a live vaccine it is a recombinant subunit RSV 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.

What is the difference between Arexvy and Abrysvo?
Arexvy and Abrysvo are both RSV vaccines that are approved for use in adults over the age of 60 to reduce their risk of developing lower respiratory tract disease (LRTD). They are also approved for adults aged 50 through 59 years (Arexvy) or aged 18 through 59 (Abrysvo) with certain chronic medical conditions (such as chronic pulmonary disease, chronic cardiovascular disease, diabetes, chronic kidney or liver disease) that put them at increased risk of LRTD caused by RSV. Abrysvo is also approved for use in pregnant women between 32 through 36 weeks gestation, to protect infants against LRTD from the moment they are born until they are 6 months of age. Arexvy is made by GSK and was approved on May 3, 2023; the first RSV vaccine to be approved for older adults. Abrysvo is made by Pfizer and was approved on May 31, 2023; the second RSV vaccine to be approved for older adults. Continue reading
