Chinese vaccine candidate based on inactivated SARS-CoV-2 virus appears safe and induces an immune response in healthy volunteers

Results from an early-phase randomised clinical trial of a Chinese vaccine candidate based on the inactivated whole SARS-CoV-2 virus (CoronaVac) are published in The Lancet Infectious Diseases journal, finding the formulation appears safe and induces an antibody response in healthy volunteers aged 18 to 59 years.

Cytokine storms play a limited role in moderate-to-severe COVID-19

Rather than life-threatening hyperinflammation, most adults with moderate-to-severe COVID-19 have a suppressed viral immune response when compared to adults with another viral respiratory infection, influenza. St. Jude Children's Research Hospital and Washington University School of Medicine in St. Louis led research that suggests most COVID-19 patients are not candidates for treatment with steroids such as dexamethasone.

Fluvoxamine may prevent serious illness in COVID-19 patients

In a preliminary study of COVID-19 patients with mild-to-moderate disease who were attempting to recover in their homes, researchers at Washington University School of Medicine in St. Louis have found that the drug fluvoxamine seems to prevent some of the most serious complications of the illness and make hospitalization and the need for supplemental oxygen less likely.

RNA structures of coronavirus reveal potential drug targets

The SARS-CoV-2 coronavirus RNA genome structure was studied in detail by researchers from the University of Groningen, the International Institute of Molecular and Cell Biology in Warsaw, and Leiden University. The RNA structures are potential targets for the development of drugs against the virus. The results were published on 10 November as 'Breakthrough paper' in the journal Nucleic Acid Research.

Pre-existing coronavirus antibodies could help protect children against new pandemic strain

Researchers at the Francis Crick Institute and University College London have found that some antibodies, created by the immune system during infection with common cold coronaviruses, can also target SARS-CoV-2 and may confer a degree of protection against the new viral strain.

In response to infection with a virus, the immune system creates antibodies to help fight it. These antibodies remain in the blood for a period after infection, and in the case of re-infection, they are able to tackle the virus again.

Scientists identify synthetic mini-antibody to combat COVID-19

The ability of SARS-CoV-2 to infect cells depends on interactions between the viral spike protein and the human cell surface protein ACE2. To enable the virus to hook onto the cell surface, the spike protein binds ACE2 using three finger-like protrusions, called the receptor binding domains (RBDs). Blocking the RBDs therefore has the potential to stop the virus from entering human cells.

Ultrapotent COVID-19 vaccine candidate designed via computer

An innovative nanoparticle vaccine candidate for the pandemic coronavirus produces virus-neutralizing antibodies in mice at levels ten-times greater than is seen in people who have recovered from COVID-19 infections. Designed by scientists at the University of Washington School of Medicine in Seattle, the vaccine candidate has been transferred to two companies for clinical development.
