Study Summary

This trial studies the safety, side effects and immune response of a VZV modRNA vaccine in adults ages 50-69. Participants receive different doses and formulations, and may stay in the study for up to 5 years.

Who is the study for?
Healthy adults aged 50-69 can join this vaccine trial against shingles. They must be able to follow the study plan and not have heart disease, bleeding issues, or a history of severe vaccine reactions. Pregnant women, those on immunosuppressants, or with recent other vaccines are excluded.Check my eligibility
What is being tested?
The trial is testing different candidates of a modified RNA shingles vaccine compared to an approved one (Shingrix). It's in two parts: Phase 1 tests safety and immune response with various doses/formulations; Phase 2 uses findings from Phase 1 for further evaluation over up to five years.See study design
What are the potential side effects?
Possible side effects include typical reactions at the injection site like pain and swelling, general symptoms such as fever or fatigue, allergic responses, and potentially others based on individual health conditions.
