Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

This research study goal is to analyze the plasma and the cells that make up part of the immune system. We want to learn how the plasma and cells work. These may influence why one person will develop an infection and another will not, or why one person develops severe symptoms of a disease while others remain without symptoms.
