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.

Structural analysis of SARS-CoV-2 can help develop COVID-19 vaccines

At the start of a COVID-19 infection, the coronavirus SARS-CoV-2 docks onto human cells using the spike-like proteins on its surface.

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.

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.

Gene editing approach removes oral herpes

Infectious disease researchers at Fred Hutchinson Cancer Research Center have used a gene editing approach to remove latent herpes simplex virus 1, or HSV-1, also known as oral herpes.

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.

Wits University begins South African trial of Novavax COVID-19 vaccine

NVX-CoV2373 is produced by the biotech company, Novavax (Maryland, U.S.A). Novavax is a late-stage biotechnology company that develops next-generation vaccines for serious infectious diseases.

Trust, fear and solidarity will determine the success of a COVID vaccine

Thousands of letters stuffed with money flooded Jonas Salk's mailbox the week after his polio vaccine was declared safe and effective in 1955. Everybody wanted his vaccine.

New type of immunotherapy extends survival of mice with triple negative breast tumors

Immunotherapies for cancer - treatments that prime the immune system to attack tumors - are valuable weapons in the anti-cancer arsenal. But some cancers are more difficult to target with this strategy than others.

With COVID vaccine trial, rural Oregon clinic steps onto world stage

From the outside, it appears to be just another suburban allergy clinic, a tidy, tan brick-and-cinder-block building set back from a busy highway and across the road from an auto parts store.

Potential inhibitors of SARS-CoV-2 identified

Now, a new study published on the preprint server bioRxiv in August 2020 reports the discovery of two inhibitors of the helicase enzyme, which is essential for viral replication and the most highly conserved non-structural coronavirus (CoV) protein.

Scientists reveal most likely order of COVID-19 symptoms

Now, a team of researchers at the University of Southern California (USC) has revealed the order of symptoms often experienced by those who infected with SARS-CoV-2. Knowing the order of the symptoms may help the patients seek medical help immediately. The research is published in the journal Frontiers in Public Health.

U.S. scientists to create coronavirus strain for human challenge trials

Now, a team of scientists in the United States plans to create a coronavirus strain that can be used for human challenge trials, a controversial type of study wherein health volunteers would be vaccinated and intentionally infected with the virus.

SARS-CoV-2 spike pocket is a putative target for antiviral design

In a methodologically rigorous study, researchers from the University of Oxford have recently shown how the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike glycoprotein harbors a lipid-binding pocket which modulates the stability of the prefusion trimer and provides conformational shielding from antibodies. Their findings are currently freely available on the bioRxiv* preprint server.

UW team receives $33,000 grant to develop model to help lower COVID-19 infections in King County

Policymakers continue to have uncertainties on how to answer important questions about the novel coronavirus -- such as when and how to reopen businesses and schools, and how to distribute a vaccine once one becomes available.

Frequently used serology test may not detect SARS-CoV-2 antibodies, shows study

Two different types of detectable antibody responses in SARS-CoV-2 (COVID-19) tell very different stories and may indicate ways to enhance public health efforts against the disease, according to researchers at The University of Texas MD Anderson Cancer Center.
