Examples of this type of preparations are: (1) convalescent plasma (i.e., plasma obtained from patients who recovered from COVID-19) (8), (2) vaccinated plasma (i.e., plasma obtained from individuals immunized with anti-COVID-19 vaccines) (8), (3) intravenous immunoglobulins (IVIg) purified from convalescent plasma (i.e., CP-IVIg) (12, 13), (4) IVIg produced from plasma of vaccinated donors (i.e., VP-IVIg), (5) monoclonal antibodies (14), and (6) animal-derived immunoglobulins (15). The gene discussed is CP; the disease is COVID-19.
