World's First Respiratory Syncytial Virus Vaccine Approved

In News
  • The US Food and Drug Administration (FDA) recently approved the world's first respiratory syncytial virus vaccine.
Respiratory Syncytial Virus
  • Respiratory syncytial virus is a respiratory virus that is extremely infectious and gives rise to indications like cough, sneezing, fever, wheezing, runny nose, and a reduced appetite.
  • This virus is air-borne as well as fomite-borne, transmitted through coughing and sneezing, through direct contact with an infected individual, or by touching objects with the virus on it.
  • In case of infection, treatments include over-the-counter pain relievers, staying hydrated, and in severe cases, hospitalisation and oxygen support.
  • In the US, respiratory syncytial virus is the most common cause of bronchiolitis, inflammation of the small airways in the lungs, and pneumonia, infection of the lungs, in children aged less than a year.
About Vaccine
  • The objective of the vaccine is to hinder respiratory syncytial virus-induced lower respiratory tract illness in elderly individuals.
  • Arexvy is an adjuvanted respiratory syncytial virus vaccine, which means that it has an adjuvant, an ingredient that helps create a stronger immune response to vaccination.
  • The trial revealed that the usage of Arexvy lowered the possibility of developing lower respiratory tract disease related to respiratory syncytial virus by 82.6 percent and reduced the chance of developing severe lower respiratory tract disease by 94.1 percent.
