New SARS-CoV-2 vaccine effective in macaques

Researchers from the biotechnology company Novavax in Gaithersburg, Maryland, have developed a vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that successfully induces immunogenicity and protection against the virus in macaques.

COVID-19 could compromise key element of immune response

Researchers at the University of Melbourne have made the unsettling discovery that infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) might compromise the activation of the CD8+ T-cell responses that would usually ameliorate disease and drive recovery in cases of respiratory disease.

Whey protein from human breastmilk inhibits SARS-CoV-2 infection

Many scientists have reported the effects of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on pregnancy and the virus has been detected in breastmilk. Now a new study published on the preprint server bioRxiv* in August 2020 shows that whey protein in human breastmilk efficiently prevents infection with SARS-CoV-2 as well as post-entry viral replication.

COVID-19 linked to type 1 diabetes and diabetic ketoacidosis in children

A team of researchers at Imperial College Healthcare NHS Trust and Imperial College London has found a link between COVID-19 and new-onset type 1 diabetes in children. The research is published in the journal Diabetes Care.

SARS-CoV-2 hijacks antiviral factors to promote infection in human lung cells

Now, a new study published in the preprint server bioRxiv in August 2020 shows that under conditions resembling those in vivo, IFNs may promote efficient viral invasion instead.

Breast milk is not a potential source of infection, indicates study

As the novel coronavirus continues to spread around the world, so do the concerns of breastfeeding mothers.Although there have been no documented cases to date of an infant contracting COVID-19 as a result of consuming infected breast milk, the critical question of whether there is potential for this form of transmission remains.

Could the high rate of mutations bring about SARS-CoV-2's extinction in India?

A new study published on the preprint server bioRxiv in August 2020 shows the importance of uncovering the dynamics of the virus with particular attention to geographic variation.

Fresh and frozen food can harbor SARS-CoV-2 for at least 21 days

A recent study published on the preprint server bioRxiv in August 2020 suggests that foodborne contamination may underlie these outbreaks and that this route of transmission should not be overlooked to contain the pandemic.

Genomics study shows multiple and diverse SARS-CoV-2 introductions in the US capital region

A recent study led by the researchers from Johns Hopkins University reveals multiple and diverse introductions of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the United States National Capital Region during the initial phase of coronavirus disease 2019 (COVID-19) pandemic. The study is currently available on the medRxiv* preprint server.

Researchers use heparin to block co-receptor for SARS-CoV-2 infection

Researchers at the University of Amsterdam have conducted a study showing that heparan sulfate proteoglycans are important co-receptors that severe acute respiratory syndrome 2 (SARS-CoV-2) requires to infect host cells.

Human microbiome trims mucosal glycans, influencing SARS-CoV-2 infection

An international team of researchers has conducted a study showing that differences in the human microbiome may influence the ability of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to infect host cells.

New 3D digital segmented models for COVID-19 diagnosis

An LSU Health New Orleans radiologist and evolutionary anatomist have teamed up to show the same techniques used for research on reptile and bird lungs can be used to help confirm the diagnosis of COVID-19 in patients.

COVID-19 patients with hypoxia respond positively to a treatment, study shows

Covid-19 patients with hypoxia respond positively to icatibant treatment, Radboud university medical center researchers wrote in JAMA Network Open.

Single-dose adenovirus-vectored vaccine protects mice against SARS-CoV-2

The researchers selected the human adenovirus type 5 on which to base their vaccine because this replication-defective vector had already been used in their Ebola vaccine, with an excellent safety and immunogenicity profile in a phase 1 trial. The current study aimed to produce a vaccine that could offer mucosal vaccination and enhanced protection against this respiratory virus.

Gut microbiome may play a part in severe COVID-19

A recent study published on the preprint medRxiv* in August 2020 reports on the evidence that the gut microbiome may play a part in severe COVID-19 infection.

Large SARS-CoV-2 outbreak on a fishing boat - neutralizing antibodies prevent infection

Now, a team of researchers at the University of Washington School of Medicine has found evidence that SARS-CoV-2 neutralizing antibodies can prevent infection in people, as they conducted a study before and after a COVID-19 outbreak on a fishing vessel.

The world is 'nowhere near herd immunity,' WHO says

Now, the World Health Organization (WHO) says that the world is nowhere near the amount of coronavirus immunity needed to induce herd immunity, where enough people would develop the antibodies to stop the spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Routine BCG immunization in infancy and COVID-19 containment in Japan

. A new study explores whether and how the practice of routine BCG vaccination of infants may have curbed the initial spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in Japan. The research is published in the Journal of Infection.

Antibody and cellular immunity in severe vs. mild COVID-19

Now, a new study published in the journal Signal Transduction and Targeted Therapy in August 2020 shows that while humoral and T-cell immune responses are more robust in severe infection, the disease activates memory T cells as part of the adaptive immune system in COVID-19 patients irrespective of disease severity.
