Safety and Serum Virus Neutralizing Antibody Responses of VYD2311, a COVID-19 Vaccine, and Coadministered VYD2311 With a COVID-19 Vaccine
Purpose
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.

Prior known or suspected SARS-CoV-2 infection within 6 months before Day 0. 5. Tests positive for current SARS-CoV-2 infection by RAT or local nucleic acid amplification test (eg, RT-PCR) on Day 0. 6. Exposure to someone with known or suspected SARS-CoV-2 infection in the 5 days before Day 0. 7. Is acutely ill, including symptoms suggestive of SARS-CoV-2 infection, in the opinion of the investigator or has a fever ≥38oC (≥100.4oF) within 14 days of Day 0. 8. Any chronic or significant medical condition that, in the opinion of the Investigator, might compromise participant safety or interfere with evaluation of the study drug or interpretation of participant safety or study results.
