Trial Summary

What is the purpose of this trial?

This trial is testing a new vaccine called mRNA-1345 to see if it can prevent lung infections caused by the RSV virus. The vaccine works by teaching the body to recognize and fight the virus. The study will include people who are at risk of these infections and will compare the effects of the vaccine to a non-treatment group.
