Study Summary

This trial is testing a new vaccine for safety and how well it works. The study will give the vaccine to two groups of people, those aged 18-64 years and those aged 65 years and older, to see if it is safe and causes an immune response. The mRNA NA vaccine is used to treat Influenza and has previously been approved by the FDA for a different condition. No patients in this trial will receive a placebo. This treatment is free.
