Collection of Plasma From People That Recovered From or Were Vaccinated Toward Emerging Infectious Diseases

The administration of convalescent plasma is often used for the treatment of emerging
infectious diseases. The purpose of this study is to collect plasma from people with high
titer antibodies for a given emerging infectious disease, which is potentially suitable for
infusion into people as part of a separate treatment study.

Prospective participants will attend a screening visit to confirm exposure/vaccination
history and undergo a clinical and laboratory assessment to ensure that they are likely to
meet plasma donation criteria. Once they have been found eligible, participants will be
referred to the NIH Clinical Center Department of Transfusion Medicine. Participants will be
asked to donate plasma at least 3 times and can donate a maximum of 20 times. Plasma
collection will occur no more frequently than every 7 days. There are no additional study
visits following plasma donation.
