Evusheld™ found to poorly neutralize Omicron in kidney transplant patients

Researchers evaluated the neutralizing antibody titers and anti-receptor-binding domain immunoglobulin G titers in sera of kidney transplant recipients who were vaccinated against COVID-19 and treated with 300 mg dosage of Evusheld™

Adaptive immunity against SARS-CoV-2 is persistent and robust in COVID-convalescent children

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection incites adaptive cellular immune responses. In many SARS-CoV-2 studies, peripheral blood is analyzed to study the immune responses. Now, a new study under consideration at the Nature Portfolio Journal analyzes the peripheral blood, tonsils, and adenoids of children to understand local and systemic immune responses to SARS-CoV-2.

Breast milk components show potent in vitro SARS-CoV-2 inhibition

Human breastmilk contains substances that can inhibit infection by SARS-CoV-2 and its variants, as well as prevent its replication.

Study confirms no preexisting B-cell immunity against SARS-CoV-2 in pre-pandemic samples

A recent study finds that there is no considerable B-cell immunity against SARS-CoV-2 in unexposed healthy individuals.

23 Mar 2022

Study discovers potent and selective human monoclonal antibodies against Omicron variant of SARS-CoV-2

In a new study, researchers discovered human monoclonal antibodies, which were specific and potent against the severe acute respiratory syndrome coronavirus 2 Omicron variant.
