Serum <scp>anti‐Spike immunoglobulin G</scp> levels in random blood donors in Italy: High‐titre convalescent plasma is easier than ever to procure

Abstract

Despite reduced anti-Spike vaccine boost deployment in the general population, we have shown here that high-titre CCP units are easier than ever to procure. This finding also has implications for the derivation of standard immunoglobulins, which are finally approaching the potency of hyperimmune serum and could soon represent an alternative to CCP.
