Official Title: A Multi-center, Multi-national, Prospective Surveillance Study of Respiratory Syncytial Virus Disease in Infants and Toddlers 6 to < 22 Months of Age
Brief Summary: The study is a multi-center, multi-national, prospective surveillance study in which the study participants will not receive a study vaccine but will provide a baseline blood sample and be followed for acute respiratory disease during 6 months.
The 6-month follow-up will occur for the most part during the Respiratory Syncytial Virus(RSV) season (based on enrollment timing and as per feasibility).
A maximum of 1000 children from 6 to < 22 months of age are planned to be enrolled in 5 to 10 countries, 1 to 2 sites per country, targeting approximately 100 participants per country.
The purpose of the study is to assess the seroprevalence and incidence of RSV disease during the study period in the targeted countries and sites for a Phase III vaccine study.
