About this study

The main purposes of this research study are to measure the safety (whether it causes any side effects), tolerability (if it does cause any side effects, how well your body is able to handle them), and reactions, both local at the injection site and systemic, that may occur in the body after receiving VYD2311, or a COVID-19 vaccine, or a combination of VYD2311 and a COVID-19 vaccine in healthy participants. This research study will measure the amount of serum virus neutralizing antibodies produced in the blood (antibodies that block a virus from infecting cells) and pharmacokinetics of VYD2311 compared to a COVID-19 vaccine, when each is administered alone or concurrently. Pharmacokinetics is the study of how a drug moves through the body, including how it is absorbed (taken into the body), distributed (spread throughout the body), metabolized (broken down in the body), and eliminated (removed from the body), and how the body affects the drug.
