South Africa SARS-CoV-2 variant B.1.351 easily evades Sputnik vaccine

The use of this vaccine in several countries in South America and eastern Europe, besides Russia, mandates that its efficacy against the new resistant variants be tested, as they are being found more commonly in these regions.Generation of replication-competent VSV bearing SARS-CoV-2 spike (rcVSV-CoV2-S). (A) Schematic of the rcVSV-CoV2-S genomic coding construct and the virus

New Technique Provides Detailed Map of Lung Pathology in COVID-19. Disease progression may not depend on the persistence of the virus, but on an overreaction of the immune system.

A team led by investigators at Weill Cornell Medicine and NewYork-Presbyterian has used advanced technology and analytics to map, at single-cell resolution, the cellular landscape of diseased lung tissue in severe COVID-19 and other infectious lung diseases. In the study, published online March 29 in Nature, the researchers imaged autopsied lung tissue in a way that

What is Cerebral Venous Sinus Thrombosis (CVST), the post adenovirus Covid-19 vaccine rare clotting complication: Vaccine Immune Thrombotic Thrombocytopenia represents a small percent of cases. Need to define other cases diagnosis and treatment.

Cerebral venous sinus thrombosis (CVST) occurs when a blood clot forms in the brain’s venous sinuses. This  prevents blood from draining out of the brain. As a result, blood cells may break and leak blood into the brain tissues, forming a hemorrhage. This chain of events is part of a stroke that can occur in adults

SARS-CoV-2 infection rates of antibody-positive compared with antibody-negative health-care workers in England: a large, multicentre, prospective cohort study (SIREN) shows that previous infection with SARS-CoV-2 induces effective immunity to future infections in most individuals.

Increased understanding of whether individuals who have recovered from COVID-19 are protected from future SARS-CoV-2 infection is an urgent requirement. In a paper published on The Lancet it was investigated whether antibodies against SARS-CoV-2 were associated with a decreased risk of symptomatic and asymptomatic reinfection. A large, multicentre, prospective cohort study was done, with participants

University of Cambridge: Communicating the potential benefits and harms of the Astra-Zeneca COVID-19 vaccine

All medical treatments have potential harms as well as potential benefits, and it’s important to be able to weigh these against each other. With vaccines, the benefits are particularly complex as they can involve benefits to others as well as to ourselves – and the harms can feel particularly acute because we take vaccines when

In two papers on NEJM researchers find VITT as responsible of AstraZeneca’s vaccine causing clots in 16 of 222 thrombosis EMA reported cases over 30 milion doses. Even US four J&J vaccine thrombosis cases under EMA evaluation scrutiny.

Doctors might have figured out why AstraZeneca Vaccine Induced Immune Thrombotic Thrombocytopenia (VITT) may cause life-threatening blood clots in a group of 16 patients with very rare cases of thrombosis and thrombocytopenia. The discovery, made in a pair of reports published online Friday in the New England Journal of Medicine, could be key to the global
