Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral-specific antibody response profiles are distinct in different age groups, according to a study published online March 22 in JAMA Network Open. He S. Yang, Ph.D., from Weill Cornell Medicine in New York City, and colleagues examined the correlation of age with the quantity and quality of SARS-CoV-2 antibody
Late Monday, the Data and Safety Monitoring Board (DSMB) notified NIAID, BARDA, and AstraZeneca that it was concerned by information released by AstraZeneca on initial data from its COVID-19 vaccine clinical trial. The DSMB expressed concern that AstraZeneca may have included outdated information from that trial, which may have provided an incomplete view of the
Researchers from the George Washington University found that aspirin may have lung-protective effects and reduce the need for mechanical ventilation, ICU admission and in-hospital mortality in hospitalized COVID-19 patients. George Washington University researchers found low dose aspirin may reduce the need for mechanical ventilation, ICU admission and in-hospital mortality in hospitalized COVID-19 patients. Final results
79% vaccine efficacy at preventing symptomatic COVID-19 100% efficacy against severe or critical disease and hospitalisation Comparable efficacy result across ethnicity and age,with 80% efficacy in participants aged 65 years and over Favourable reactogenicity and overall safety profile The AstraZeneca US Phase III trial of AZD1222 demonstrated statistically significant vaccine efficacy of 79% at preventing
13 cases of a venous cerebral sinus or cerebral vein thrombosis following >1,6 million doses were reported in Germany. The thrombosis occurred 4-16 days after the vaccination with the AstraZeneca COVID-19 vaccine in twelve women and one man aged 20–63 years. The patients had one at the same time thrombosis and thrombocytopenia due to autoantibodies.
EMA has just published the new product information leaflet for Astrazeneca Covid-19 vaccine after investigations of thrombosis rare cases reported. In the section 4.4 Special warnings and precautions for use has been added the following: Thrombocytopenia and coagulation disordersA combination of thrombosis and thrombocytopenia, in some cases accompanied by bleeding, hasbeen observed very rarely following
From the early days of the COVID-19 pandemic, a distinct coagulation disturbance of SARS-CoV-2 infection has been recognized. This thrombo-inflammatory phenotype, characterized by endotheliopathy, hypercoagulability, and coagulation activation, results in an increased risk of thromboembolic events. Initial observational cohort studies described high rates of venous thromboembolism (VTE) in critically ill patients with COVID-19, despite consistent use
In The Lancet, Zhenyu He and colleagues report their cross-sectional study of serological responses of morethan 9500 individuals from 3600 households in Wuhan, the early epicentre for the COVID-19 outbreak. The study was initiated shortly after lockdown in Wuhan ceased in April, 2020, with follow-up over two timepoints (June and October–December, 2020). In this cross-sectional,
CDC’s national genomic surveillance program identifies new and emerging SARS-CoV-2 variants to determine implications for COVID-19 diagnostics, treatments, or vaccines authorized for use in the United States. Monitoring the spread of emerging variants in the United States relies on widespread, rapid sequencing. To accelerate sequencing in the United States, CDC has contracted with commercial diagnostic laboratories, and,
EMA’s safety committee, PRAC, concluded its preliminary review of a signal of blood clots in people vaccinated with COVID-19 Vaccine AstraZeneca at its extraordinary meeting of 18 March 2021. The Committee confirmed that: the benefits of the vaccine in combating the still widespread threat of COVID-19 (which itself results in clotting problems and may be fatal)
