SARS-CoV-2 hyperimmune intravenous human immunoglobulins neutralizes Omicron subvariants BA.1, BA.2, BA.2.12.1, BA.3 and BA.4/BA.5 for treatment of COVID-19

alexandrossfakianakis shared this article with you from Inoreader SARS-CoV-2 hyperimmune intravenous human immunoglobulins neutralizes Omicron subvariants BA.1, BA.2, BA.2.12.1, BA.3 and BA.4/BA.5 for treatment of COVID-19 via Clinical Infectious Diseases Advance Access ABSTRACT Our study demonstrates that neither 2020-convalescent plasma (CP) nor 2019/2020-immunoglobulin (IVIG) neutralize Omicron subvariants BA.1 to BA.5. In contrast, hyperimmune 2020-hCoV-2IG lots neutralized Omicron VOCs, similar to 2022-CP from BA.1 breakthrough infections. Therefore, high-titer hCoV-2IG and CP could be evaluated for treatment of high-risk individuals infected with circulating Omicron subvariants. View on Web
