Convalescent Plasma

Convalescent plasma is the liquid part of blood collected from someone who has recovered from an infection, such as COVID-19. It contains antibodies—proteins that help fight the virus. When transfused into an actively infected patient, these antibodies can boost the immune response, potentially helping the person recover faster. It’s a form of passive immunity, meaning the patient receives ready-made defenses instead of producing their own. This therapy is mainly used in emergency or clinical settings and requires careful blood matching and screening to ensure safety.
