Study Summary

This trial will compare the efficacy of a new quadrivalent influenza modRNA vaccine to a licensed inactivated influenza vaccine in healthy adults 18 years and older.

Who is the study for?
Adults over 18 who are healthy and have had a recent colonoscopy can join this flu vaccine study. They must be able to follow the study plan and give informed consent. People with egg or chicken protein allergies, severe reactions to vaccines, or certain medical or psychiatric conditions cannot participate.Check my eligibility
What is being tested?
This Phase 3 trial is testing a new quadrivalent influenza modRNA vaccine against the standard flu shot in adults. Participants will receive one dose of either the new vaccine or the standard one, and researchers will compare their effectiveness and safety.See study design
What are the potential side effects?
Potential side effects from both vaccines may include pain at injection site, fatigue, headache, muscle pain, feverish feelings, joint pain; however specific side effects for the modRNA vaccine are not detailed as it's under evaluation.
