Infant RSV Immunity Study
Understanding the Impact of Early-life RSV Infections on Infant Immunity and Long-term Health
Source: ClinicalTrials.gov · Last updated 17 Jun 2026
Brief summary (registry, in English)
Respiratory Syncytial Virus (RSV) is a main global cause of respiratory illness and death in infants. Previous infant vaccine trials have failed to demonstrate protection. Moreover, RSV infection during early infancy, particularly in infants younger than 4 months of age, is associated with more severe disease, reduced immune protection, and an increased risk of developing childhood asthma. This study aim to investigate the immunological and long-term health effects of a first exposure to RSV early (\<4 months) versus late (\>6-9 months) in infancy.
