Polyclonal immunoglobulins for covid-19 pre-exposure prophylaxis in immunocompromised patients

Immunocompromised patients remain at high risk of COVID-19 morbidity and mortality. After recent Omicron sublineages gained full resistance to Evusheld ™, they are left without effective pre-exposure prophylaxis. We review here arguments to support the growing role of regular immunoglobulin (IG) infusions at protecting against COVID-19. Since there is evidence for neutralizing antibody titers approaching the ones seen in hyperimmune sera, and sin ce some categories of patients at risk for COVID-19 progression are already under preexposure prophylaxis with IG, this cost cost-effective strategy should be urgently investigated in randomized clinical trials.
