Summary

Background:

People who get infected with COVID-19 have an unpredictable risk to worsen and die. This makes it hard to decide who can quarantine at home and who should be treated at a hospital. Researchers think the risk may be related to how a person s B and T cells respond to the virus. B and T cells are the major components of a person s immune response. B and T cells responding to the virus with a favorable pattern may lead to recovery, and this favorable pattern may be helpful to establish. If people in a vaccine trial get this same favorable pattern when responding to a vaccine, this may be a useful early signal that the vaccine will be successful.

Objective:

To examine how immune cells respond to COVID-19 infection.

Eligibility:

Adults ages 18 and older who have a confirmed or suspected COVID-19 infection or had COVID-19 in the past.

Also, healthy donors with no suspected COVID-19 infection

Design:

Participants will be screened with medical record review.

Participants will be tested with a research assay to determine who was infected with COVID-19 and who was not. This test will be used to understand research results, not to advise patients.

Participants with active infection must be isolated, usually in a hospital.

Other participants may give blood samples at NIH or at their local doctor s office or lab.

Participants may give blood samples up to three times a week for a total of ten times, and may also give blood samples after starting a vaccine trial.

Participants will be contacted by phone or email every 2 months for up to 2 years.
