When the B.1.1.7 variant of SARS-CoV-2 was first detected in the UK in December 2020 it was accompanied by unsubstantiated claims of increased transmissibility and virulence. The results of a hospital-based study in London reveals no association of the variant with severe disease in this cohort. In a note published by NERVTAG on 21 January …
In our quest to stop the COVID-19 pandemic by vaccination, we have been myopically focussed on inducing antibodies against the spike protein. As variants of SARS-CoV-2 have emerged that reduce the ability of such antibodies to block infection, concern has arisen that we will not be able to halt the disease. Such concerns appear to …
In recent months variants of SARS-CoV-2 have been detected that are unusual in that they have many more genome mutations than previously found. These have been called ‘variants of concern’ (VOC) as it has been suggested that the genome mutations might impact transmission, immune control, and virulence. Below I cover each of these issues separately. …
The Biden-Harris administration has released a document describing its plans to bring the United States out of the ‘worst public health crisis in a century’. It is a roadmap for not only ending the pandemic in the US, but to re-establish leadership in the global health care community and provide assistance to other countries. I …
by Paul Bieniasz Dr. Bieniasz is Professor and Investigator of the Howard Hughes Medical Institute at Rockefeller University. As viruses go, SARS-CoV-2, is quite easy to neutralize with antibodies and, it turns out, straightforward to generate effective vaccines based on the spike protein. Perhaps, even probably, those two properties are causally related. Moreover, it appears …
Daniel Griffin provides a clinical report on COVID-19, then we discuss Bill Foege’s letter to CDC director Robert Redfield, the false promise of herd immunity for COVID-19, secret blueprints for SARS-CoV-2 vaccine trials released, and neuropilin-1 as a possible entry protein for the virus.
