A Study of LY3832479 (LY-CoV016) in Healthy Participants 1

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to test the safety and tolerability of LY3832479 when it is given by injection just under the skin to healthy participants. Blood tests will be done to check how much LY3832479 is in the bloodstream and how long the body takes to eliminate it. Participation could last up to 16 weeks and may include up to six visits to the study center, with a one-week overnight stay.
