Experimental COVID-19 vaccine protects upper and lower airways in nonhuman primates
Two doses of an experimental vaccine to prevent coronavirus disease 2019 (COVID-19) induced robust immune responses and rapidly controlled the coronavirus in the upper and lower airways of rhesus macaques exposed to SARS-CoV-2, report scientists from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. SARS-CoV-2 is the virus that causes COVID-19.

Another mRNA-based vaccine candidate protects animals against SARS-CoV-2
An experimental messenger RNA (mRNA)-based vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) elicits protective immune responses in mice and non-human primates, researchers report on July 23rd in the journal Cell. Two injections of the vaccine were sufficient to induce robust immunity, completely preventing SARS-CoV-2 infection in mice.

COVID-19 vaccine innovation could dramatically speed up worldwide production
Responding to a need to quickly develop billions of doses of lifesaving COVID-19 vaccines, a scientific team at The University of Texas at Austin has successfully redesigned a key protein from the coronavirus, and the modification could enable much faster and more stable production of vaccines worldwide.

Neutralizing antibodies isolated from COVID-19 patients may suppress virus
Researchers at Columbia University Irving Medical Center have isolated antibodies from several COVID-19 patients that, to date, are among the most potent in neutralizing the SARS-CoV-2 virus.
These antibodies could be produced in large quantities by pharmaceutical companies to treat patients, especially early in the course of infection, and to prevent infection, particularly in the elderly.
Scientists uncover SARS-CoV-2-specific T cell immunity in recovered COVID-19 and SARS patients
The study by scientists from Duke-NUS Medical School, in close collaboration with the National University of Singapore (NUS) Yong Loo Lin School of Medicine, Singapore General Hospital (SGH) and National Centre for Infectious Diseases (NCID) was published in Nature.

Drug linked to 45% lower risk of dying among COVID-19 patients on ventilators
Critically ill COVID-19 patients who received a single dose of a drug that calms an overreacting immune system were 45% less likely to die overall, and more likely to be out of the hospital or off a ventilator one month after treatment, compared with those who didn't receive the drug, according to a new study by a team from the University of Michigan.
