A spike in COVID-19 has occurred in Southern California since October 2020. Analysis of SARS-CoV-2 in Southern California prior to October indicated most isolates originated from clade 20C that likely emerged from New York via Europe early in the pandemic.1 Since then, novel variants of SARS-CoV-2 including those seen in the […]
(Reuters) – Antibodies induced by the Pfizer/BioNTech and Moderna vaccines and the antibody therapy from Regeneron Pharmaceuticals all are able to neutralize a coronavirus variant on the rise in New York, lab experiments show. The New York variant contains mutations – E484K, S477N and D235G – that experts feared might […]
Two U.K. cohort studies reported excess risk for death among those infected with B.1.1.7. Several emerging SARS-CoV-2 variants of concern (VOCs) appear to have heightened infectivity and ability to evade natural or vaccine-derived immunity. Among the most prevalent of these is the B.1.1.7 VOC, first isolated in England in October […]
New York state confirmed its first case of the P.1 coronavirus variant, which was first identified in Brazil and is now the dominant variant there, according to The New York Times.
