Could a nasal spray prevent coronavirus transmission?

A nasal antiviral created by researchers at Columbia University Vagelos College of Physicians and Surgeons blocked transmission of SARS-CoV-2 in ferrets, suggesting the nasal spray also may prevent infection in people exposed to the new coronavirus, including recent variants.

A machine-learning approach to finding treatment options for COVID-19

When the COVID-19 pandemic struck in early 2020, doctors and researchers rushed to find effective treatments. There was little time to spare. "Making new drugs takes forever," says Caroline Uhler, a computational biologist in MIT's Department of Electrical Engineering and Computer Science and the Institute for Data, Systems and Society, and an associate member of the Broad Institute of MIT and Harvard.

One dose of COVID-19 vaccine provokes strong immune response in those previously infected

Although clinical trial data are encouraging, real-world evidence with regard to the COVID-19 vaccine remains scarce. In particular, response to the vaccine among those previously infected with SARS-CoV-2 is still not completely understood.

Researchers from Bar-Ilan University and Ziv Medical Center now report preliminary evidence that people previously infected with the virus responded very strongly to one dose of the Pfizer vaccine, regardless of when they were infected and whether or not they had detectable antibodies against COVID-19 prior to receiving the vaccine.

Scientists urge for investment now in highly potent vaccines to prevent the next pandemic

As new COVID-19 variants begin to throw vaccine efficacy in question, two leading scientists are calling for health agencies to invest in the development of vaccines that would be broadly effective against many different variants and strains of potential pandemic viruses.

In a commentary article published in the journal Nature, Dennis Burton, PhD, and Eric Topol, MD, of Scripps Research call for governments to provide significant funding support for rational vaccine design based on broadly neutralizing antibodies.

Anticancer drug may improve outcome for severe COVID-19 patients

Treating severe COVID-19 patients with the anticancer drug bevacizumab may reduce mortality and speed up recovery, according to a small clinical study in Italy and China that was led by researchers at Karolinska Institutet in Sweden between February and April 2020. On average, blood oxygen levels, body temperature and inflammatory markers significantly improved in patients treated with a single dose of bevacizumab in addition to standard care.

Novel molecules to combat asthma and COVID-related lung diseases discovered

A study designed to study how the immune system impacts gut bacteria - has led to the extraordinary discovery of two molecules that can not only provide profound protection in experimental models of asthma but can also substantially reduce the severity of an attack.

Neither of these molecules, one of which is already commercially available as a dietary supplement, were previously known to have an effect on asthma - and they also appear, from animal studies, to have a role in treating the respiratory illness that is prevalent, and often fatal, in people with serious COVID-19.

COVAX announces new agreement, plans for first deliveries

COVAX, the global initiative to ensure rapid and equitable access to COVID-19 vaccines for all countries, regardless of income level, today announced the signing of an advance purchase agreement with Pfizer for up to 40 million doses of the Pfizer-BioNTech vaccine candidate, which has already received WHO emergency use listing. Rollout will commence with the successful negotiation and execution of supply agreements.
