Brief Summary

This phase 1 study in Australia will evaluate the safety, reactogenicity and immunogenicity of the Bivalent Recombinant Respiratory Syncytial Virus (RSV) Vaccine (CHO Cell) (SCB-1019T) in children 2-\<6 years of age.

Detailed Description

This Phase 1 randomized, placebo-controlled, observer-blind study will evaluate the safety, reactogenicity and immunogenicity of different formulations of SCB-1019T vaccine in children 2-\<6 years of age. A placebo is used as a control in the study because there is no licensed RSV comparator vaccine available for young children globally.
