Clinical trials

The goal of this study is to evaluate the safety and immunogenicity of an investigational varicella vaccine in children. Researchers will compare the investigational vaccine, NBP608, with licensed varicella vaccines. The study includes children aged 12 months to 12 years. Participants will be randomly assigned to receive either the investigational vaccine (NBP608) or licensed varicella vaccines. Participants will: Receive two subcutaneous injections of a study vaccine administered. Visit the study clinic seven times over approximately 15 months. Receive follow-up phone calls 7 days after each vaccination to monitor for safety.
