About this trial
Respiratory syncytial virus (RSV) is a common cause of respiratory tract infections leading to hospitalizations in infants and in elderly. Arexvy is an approved vaccine for the prevention of RSV infection, however, data on its efficacy in individuals aged 80 years and older remain limited. This study aims to evaluate potential differences in immune responses to Arexvy vaccination between adults aged ≥80 years and those aged 60-65 years.
