The study also tests how well current vaccines resist emerging variants....
Vancouver, Canada (26 August 2021) In June 2020, The TOGETHER Trial was established as an adaptive platform randomised clinical trial to test a range of potential treatments for COVID-19 that might be suitable for clinical use in a community setting in Brazil and other low- and middle-income countries. The trial specifically tested each treatment’s potential to prevent clinical worsening of COVID-19 requiring...
by University of Oxford Graphical abstract. Credit: DOI: 10.1136/bmj.n1931 Researchers from the University of Oxford have today announced the results of a study into thrombocytopenia (a condition with low platelet counts) and thromboembolic events (blood clots) following vaccination for COVID-19, some of the same events which have led to restricted use of the Oxford-AstraZeneca vaccine in...
by Erik Robinson, Oregon Health & Science University Credit: Pixabay/CC0 Public Domain A new laboratory study from Oregon Health & Science University finds that blood serum drawn from people previously vaccinated or naturally infected show “significantly reduced” defense against two widely circulating variants of the novel coronavirus SARS-CoV-2. Researchers said that their findings emphasize the importance of...

Synthetic peptides could reinforce this defense but don’t last long in...

The GCARE team used sensors to monitor pollution particles concentration, map how those particles varied during different settings in...
by: Russell Falcon (KXAN) — After a recent resurgence in several states, health officials are warning residents to be aware of a dangerous of an unauthorized “treatment” for COVID-19 — often being taken with dangerous consequences. We know Texans are feeling the impact of the coronavirus in ways unlike any crisis in the state’s history. That’s...
Moderately ill patients hospitalized with COVID-19 have better chances of survival if treated with therapeutic-dose anticoagulation, according to an international study involving 121 sites, including UT Southwestern Medical Center. Moderately ill COVID-19 patients treated with therapeutic-dose anticoagulation with unfractionated or low molecular-weight heparin were 27% less likely to need cardiovascular respiratory organ support such as intubation, said Ambarish...

Nasopharyngeal (NP) swabs—long, medical-grade probes used to collect samples from...
by University of Chicago Credit: Unsplash/CC0 Public Domain Increasingly, research shows many people who have weakened immune systems haven’t been able to receive full protection from their COVID-19 vaccines. Unlike healthy people who’ve been vaccinated against SARS-CoV-2, the virus that causes COVID-19, immunocompromised people’s bodies may not produce enough protective antibodies after two doses of the...
