New bivalent vaccine delivers robust cell-mediated and humoral immunity against SARS-CoV-2

In a groundbreaking bioRxiv study, US researchers demonstrate the capability of next-generation bivalent human adenovirus serotype 5 (hAd5) vaccine for inducing both cellular and humoral immunity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – using both an S protein sequence optimized for cell surface expression and a conserved nucleocapsid antigen designed to be transported to the endosomal subcellular compartment.

Meta-analysis shows 57% mortality reduction with convalescent plasma in COVID-19

Now, a new study published on the preprint server medRxiv in July 2020 reports that an older treatment modality, namely, the use of convalescent antibody-rich plasma, brings down the mortality rate in hospitalized COVID-19 patients by an astonishing 57%. This adds evidence for the use of convalescent plasma in the treatment of high-risk patients.

Researcher uses in silico analysis of SARS-CoV-2 spike protein to fast-track passive immunity

With millions of COVID-19 cases reported across the globe, people are turning to antibody tests to find out whether they have been exposed to the coronavirus that causes the disease. But what are antibodies? Why are they important? If we have them, are we immune to COVID-19? And if not, why not?

Novel vaccine candidate robustly protects non-human primates against SARS-CoV-2

The development of a safe and effective vaccine will likely be required to end the COVID-19 pandemic. A group of scientists, led by Beth Israel Deaconess Medical Center immunologist Dan H. Barouch, MD, PhD, now report that a leading candidate COVID-19 vaccine developed at BIDMC in collaboration with Johnson & Johnson raised neutralizing antibodies and robustly protected non-human primates against SARS-CoV-2, the virus that causes COVID-19.

New test rapidly determines neutralizing antibodies against Sars-Cov-2

To determine immunity to Sars-Cov-2 and the effectiveness of potential vaccines, the amount of neutralizing antibodies in the blood of recovered or vaccinated individuals must be determined.

Study finds synthetic neutralizing/enhancing antibodies to SARS-CoV-2

A new study published on the preprint server bioRxiv in July 2020 reports the discovery of some antibody molecules that have powerful enhancing or neutralizing activity against the virus, in a library of synthetic antibodies. These hold the promise of being useful for the prevention or treatment of this illness.

Iota-carrageenan from red seaweed inhibits SARS-CoV-2 in laboratory conditions

In a recent bioRxiv paper, a research group from the Marinomed Biotech biopharmaceutical company in Austria showed that a sulfated polysaccharide iota-carrageenan has the propensity to inhibit cell entry of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by using an in vitro neutralization assay.

SARS-CoV-2 exposure five times more likely among Black and Hispanic pregnant women

Black and Hispanic pregnant women in Philadelphia are five times as likely as white and Asian women to have been exposed to the novel coronavirus, according to a new study led by Scott Hensley, PhD, an associate professor of Microbiology in the Perelman School of Medicine at the University of Pennsylvania, and Karen Marie Puopolo, MD, PhD, an associate professor of Pediatrics and neonatologist at the Children's Hospital of Philadelphia. The study was published today in Science Immunology.
