NCT ID NCT04803370
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether giving hospitalized COVID-19 patients two doses of plasma from people who had recovered from COVID-19, on top of standard care, helps them recover faster. 55 adults with pneumonia or low oxygen levels took part. The main goal was to see if this treatment improves their condition using a standard severity scale.
