Current immune treatment directed to avoid viral replication relies mainly in convalescent plasma and monoclonal antibodies (mAbs). No clinical benefit for convalescent plasma has been reported in a meta-analysis and systematic review compared to standard of care. MAbs are recombinant proteins capable to bind with SARS-CoV-2 preventing its entrance into cells. Several mAbs have shown reduction in viral load and/or progression of the disease such as casirivimab-imdevimab, bamlanivimab-etesevimab and sotrovimab. After the apparition of Omicron variant, it has been reported that sotrovimab retained its activity whereas the other two combinations exhibited loss of neutralizing activity. Several aspects as the target population, timing and doses, serological patient status and evolution of variants still require attention, monitorization and further studies for knowledge gaps.
