Summary

This trial aims to test the safety and effectiveness of mRNA-1010 compared to another flu vaccine in preventing flu-like illness caused by different types of flu viruses.

Who is the study for?
This trial is for adults aged 50 years or older. It's designed to test the safety and effectiveness of a new flu vaccine called mRNA-1010 compared to licensed flu vaccines like Fluarix® and Influsplit®.
What is being tested?
The study compares the new mRNA-1010 vaccine with established influenza vaccines. Participants will receive one type of vaccine and be monitored for their body's reaction and protection against flu-like symptoms caused by influenza A or B.
What are the potential side effects?
Possible side effects may include typical reactions at the injection site, such as pain, redness, swelling, as well as general symptoms like fever, fatigue, headache, muscle aches.
