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.

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.

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.

Research shows how smell loss linked to Covid-19 differs from the common cold

New research from a European group of smell disorder experts, including Prof Philpott at the University of East Anglia, shows how smell loss associated with Covid-19 infection differs from what you typically might experience with a bad cold or flu.

COVID immunity related to how bad you get it

Researchers at Stanford University in California have shown that severely ill patients hospitalized with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection develop significantly higher levels of antibodies against the virus than asymptomatic individuals and outpatients.

Rare COVID-19 related illness in children causes profound immune changes

Researchers have uncovered how the immune system is altered in a rare COVID-19 related illness in children referred to as paediatric inflammatory multisystem syndrome (PIMS-TS).

Multivitamin, mineral supplements may bolster the immune system of older adults

Older adults who took a daily multivitamin and mineral supplement with zinc and high amounts of vitamin C in a 12-week study experienced sickness for shorter periods and with less severe symptoms than counterparts in a control group receiving a placebo.

When a SARS-CoV-2 vaccine arrives, who should be vaccinated first?

This new study by the researchers at Fred Hutchinson Cancer Research Center and the University of Washington, Tacoma and published on the preprint server medRxiv in August 2020 describes one viewpoint concerning the optimized allocation of the vaccine, showing that under different efficacy scenarios, either the old or the young may be the best candidates for initial vaccination.

Majority of recovered COVID-19 patients have low neutralizing antibody titers

Now, a new study by researchers at New York University and published on the preprint server bioRxiv* in August 2020 reports on the type and intensity of anti-SARS-CoV-2 antibodies in recovered COVID-19 patients and the implications of these findings.

Mild COVID-19 cases can trigger robust memory T cell responses

Mild cases of coronavirus disease 2019 (COVID-19) can trigger robust memory T cell responses, even in the absence of detectable virus-specific antibody responses, researchers report August 14 in the journal Cell.

Pre-COVID-19 coronavirus immunity does not protect against SARS-CoV-2

A recent study by researchers in France that's currently available on the medRxiv* preprint server claims that having previous immunity against common coronaviruses (alpha and beta) cannot protect against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
