Respiratory syncytial virus (RSV), [a] also called human respiratory syncytial virus (hRSV) and human orthopneumovirus, is a virus that causes infections of the respiratory tract. It is a negative-sense, single-stranded RNA virus. [2] Its name is derived from the large cells known as syncytia that form when infected cells fuse. [2] [3]
A respiratory syncytial virus vaccine, or RSV vaccine, is a vaccine that protects against respiratory syncytial virus. [1] RSV affects an estimated 64 million people and causes 160,000 deaths worldwide each year. [2] The RSV vaccines Arexvy , [3] Abrysvo , [4] and Mresvia [5] are approved for medical use in the United States.
