Official title A Study on the Safety of an Investigational Chickenpox Vaccine, When Given to Healthy Children, 12 to 15 Months of Age
ClinicalTrials.gov ID: NCT06693895
What this study is testing
What is Investigational varicella vaccine?
Investigational varicella vaccine is an investigational medicine, given as an injection under the skin, being studied as a potential treatment for chickenpox.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The purpose of this study is to assess how well-tolerated GSK's investigational varicella vaccine (VNS Vaccine) is, in comparison to an already approved varicella vaccine (VV) known as Varivax. The study will be conducted on healthy children aged 12 to 15 months, and who have neither contracted varicella nor received a varicella vaccination.
