Heat Biologics SARS-CoV-2 vaccine generates potent T cell response in pre-clinical trial

The COVID-19 pandemic is still creating economic and health-related impact over the world. A new study published on the preprint server bioRxiv in August 2020 shows that a gp96-Ig-secreting vaccine candidate based on the expression of full-length spike protein generates a potent T cell response.

More evidence mask wearing works to contain COVID-19 spread

A team of American researchers has looked at the effects of wearing face masks and the prevention of the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) between individuals. As of today, over 5.8 million people in the USA have been infected with the virus. This new study titled, “Mask Wearing and Control of SARS-CoV-2 Transmission in the United States,” is published on the preprint server medRxiv*.

Global survey reveals hesitancy in potential acceptance of a COVID-19 vaccine

A recent study, currently available on the medRxiv* preprint server, shows that willingness to vaccinate against coronavirus disease (COVID-19) is insufficient in 19 countries that were surveyed – highlighting the need for targeted interventions to increase and sustain public acceptance of an incoming COVID-19 vaccine.

WHO African Region now certified as wild polio-free after four years

Today, the Africa Regional Certification Commission certified the WHO African Region as wild polio-free after four years without a case. With this historic milestone, five of the six WHO regions – representing over 90% of the world's population – are now free of the wild poliovirus, moving the world closer to achieving global polio eradication.

Inhaled steroid ciclesonide suppresses SARS-CoV-2 replication in vitro

A new paper by researchers at Japan’s National Institute of Infectious Diseases and published on the preprint server bioRxiv in August 2020 reports the in vitro suppression of coronavirus (CoV) replication by an inhaled corticosteroid (ICS) ciclesonide.

Monoclonal antibodies may be a better choice than convalescent plasma for treating COVID-19

A team of researchers from the Netherlands demonstrated that prophylactic treatment with a high dose of human convalescent plasma or by using concentrated monoclonal antibodies could protect against disease following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in an animal model. However, no protective effect was observed with a ten-fold lower dose of convalescent plasma. The results are currently available on the bioRxiv* preprint server.

High SARS-CoV-2 antibody seroprevalence, low mortality at Austrian COVID-19 epicenter

Now, a new study reported on the preprint server medRxiv* in August 2020 describes a high seroprevalence in an Austrian ski resort, which is considered to be the source of the European outbreak.

Allowing low-level CMV infection may boost immunity in stem cell transplant recipients

Patients who develop cytomegalovirus infections after allogeneic stem cell transplantation may be able to develop an immunity against the virus, strengthen their immune system and reduce reliance on strong antiviral medications, a team of cellular-therapy specialists from Roswell Park Comprehensive Cancer Center has found.

Inhaled steroids reduce SARS-CoV-2-related genes in COPD

A new study published on the preprint server medRxiv* aims to explore the effects of treatment with ICS on the expression of specific genes related to SARS-CoV-2 infection in bronchial epithelial cells in a prospective interventional design.

Health experts provide guidelines on scientific investigation of synbiotics

Chances are you've heard of or even taken probiotics: supplements delivering "good microbes" to the gut, providing a wide range of health benefits. If you're really up on your gut health, you may also be aware of prebiotics: supplements designed to fuel the good microbes already living in our guts.

Study explains the linear growth of COVID-19 infection curve

With the first COVID-19 epidemic peak behind them, many countries explained the decrease of infection numbers through non-pharmaceutical interventions. Phrases like "social distancing" and "flatten the curve" have become part of common vocabulary.

World's first confirmed case of SARS-CoV-2 re-infection

A team of researchers at the University of Hong Kong said that they have proven that a 33-year-old man was infected by the SARS-CoV-2 virus for a second time. The man was discharged from a hospital in April but contracted the infection again after returning from Spain via the United Kingdom in August.

Single dose nasal vaccine against SARS-CoV-2 shows promise in animal studies

Now researchers at the Washington University School of Medicine in St. Louis have worked on developing a candidate vaccine against the infection that could be administered in a single dose via a nasal spray rather than an injection. In their preliminary studies using lab mice, this single dose of the nasal vaccine successfully prevented the infection with the novel coronavirus.
