Clinical Trial Summary

The goal of this bridging study is to assess the safety and immunogenicity of BARYCELA inj. in healthy Vietnamese children aged between 12 months to 12 years. The main questions it aims to answer are:

• Safety of BARYCELA inj. (Live attenuated varicella vaccine for injection)

• Immunogenicity of BARYCELA inj. (Live attenuated varicella vaccine for injection)

Participants will be administered subcutaneously with a single dose(0.5 mL dose) of the BARYCELA inj.(MG1111) on the upper arm (brachia lateral).
