Additional Study Information: We are looking for volunteers who have recovered from COVID-19 to donate blood for treatment of others with this virus. Your plasma donation will help up to three people who are currently fighting this virus. Due to the high volume of inquiries, please send an inquiry through RecruitMe by clicking the "Do You Qualify" button. We're receiving a large number of requests about this study. We are working around the clock to enroll eligible donors. We will contact you as soon as we can by phone or email. Please note that our calls may show up as "potential spam" or "blocked" as we have protected our study staff's personal phone numbers. Thank you in advance for your patience!
