mRNA EBV vaccine in healthy young adults
Official title: A Phase 1, Dose Escalation, Placebo-Controlled Study to Evaluate the Safety and Immunogenicity of VXCO-102, a mRNA Vaccine Targeting Epstein-Barr Virus (EBV) in Healthy Young Adults
Run by Vaccine Company, Inc, a wholly owned subsidiary of Eli Lilly and Company · NCT07557602 · Data updated 2026-11-12
A first-in-human, dose-escalation study will test an mRNA vaccine (VXCO-102) to see if it is safe and can provoke an immune response in healthy 18–25 year olds.

Is this trial a fit for you?
✓Likely a good fit
Healthy adults aged 18–25 who meet all inclusion criteria and have no conflicting medical or pregnancy plans during the study.
✕Probably not a fit
Individuals with significant medical conditions, recent vaccines, or those needing immunosuppressants during the study may not benefit from participation.

What this trial studies
This Phase 1, dose-escalation trial evaluates the safety, tolerability, and immune response of VXCO-102 against Epstein-Barr virus in healthy young adults. Participants are recruited at multiple sites in Australia and receive VXCO-102 or placebo with a booster at week 8 after a sentinel safety check in each dose cohort. Up to 90 individuals will be enrolled, monitored through clinical assessments, lab tests, and adverse event reporting. The study includes strict exclusion criteria to minimize risk, including recent vaccination history and potential pregnancy. Primary aims focus on safety and immunogenicity rather than efficacy.
Why it matters
Potential benefit: If successful, the vaccine could advance understanding of EBV vaccination and pave the way for future studies that might reduce EBV-related disease burden.
How similar studies have gone: Earlier vaccine approaches for EBV are early-stage; this is a first-in-human trial to test safety and immunogenicity of an EBV-targeting mRNA vaccine in humans.
