Increased Potency and Breadth of SARS-CoV-2 Neutralizing Antibodies After a Third mRNA Vaccine Dose.

The omicron variant of SARS-CoV-2 infected very large numbers of SARS-CoV-2 vaccinated and convalescent individuals . The penetrance of this variant in the antigen experienced human population can be explained in part by the relatively low levels of plasma neutralizing activity against Omicron in people who were infected or vaccinated with the original Wuhan-Hu-1 strain . The 3 mRNA vaccine dose produces an initial increase in circulating anti-Omicron neutralizing antibodies, but titers remain 10-20-fold lower than against Wuhan-Hu-1 and are, in many cases, insufficient to prevent infection .

Expert Consensus Statements on the Use of Corticosteroids in Non-severe COVID-19.

Introduction: There is strong evidence for the use of corticosteroid in the management of severe coronavirus disease-2019 (COVID-19). However, there is still uncertainty about the timing of corticosteroids. We undertook a modified Delphi study to develop expert consensus statements on the early identification of a subset of patients from non-severe COVID-19 who may benefit from using corticosteroids.

Anti-SARS-CoV-2 receptor-binding domain antibody evolution after mRNA vaccination.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection produces B cell responses that continue to evolve for at least a year. During that time, memory B cells express increasingly broad and potent antibodies that are resistant to mutations found in variants of concern. As a result, vaccination of coronavirus disease 2019 (COVID-19) convalescent individuals with currently available mRNA vaccines produces high levels of plasma neutralizing activity against all variants tested.

Massive hemoptysis causing mortality in a post COVID-19 infected Asian male patient: Presenting as pulmonary mucormycosis, pulmonary tuberculosis and later sino-nasal mucormycosis.

While the developed nations are discussing giving a third dose of the COVID-19 vaccine to immunocompromised individuals, there are still challenges that are of global concern, especially in developing countries. The Delta variant which is predominantly responsible for the disease burden has now been reported in over 148 countries. The catastrophe caused in the Indian subcontinent has highlighted some associations, most notable being the unprecedented rise in the cases of mucormycosis in COVID-19 patients referred to as CAM (COVID-19 associated mucormycosis).
