What this study is testing
What is blood samples collection?
blood samples collection is an investigational medicine, being studied as a potential treatment for immunization.
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
- Vaccine protection depends on a specific adaptive immune memory. However, a little-explored aspect of certain live vaccines may provide beneficial, non-specific protection against infections or pathogens other than the one from which the vaccine is derived.
