Figure 1
Scheme for using convalescent plasma for COVID-19. An individual who has had COVID-19 and has recovered has their blood drawn and screened for virus neutralizing antibodies. Once identified, high levels of virus neutralizing antibodies can be administered prophylactically to prevent infections in high-risk cases in vulnerable individuals with underlying medical conditions, healthcare professionals and individuals with exposure to confirmed COVID-19 cases. In addition, convalescent serum can potentially be used in individuals with clinical illness to reduce symptoms and mortality. The effectiveness of this approach is not known, but historical experience suggests that convalescent sera may be more effective in preventing disease than in treating established disease.
