Comparing the transmission routes of two SARS-CoV-2 variants of concern

The research team had previously identified the UK variant as having higher viral RNA shedding than the D614G variant. However here, they wanted to compare the transmission of such variants through different routes of potential infection: direct contact, aerosol (airborne droplets), and fomite (objects which may be contaminated and therefore spread infectious agents).

Survey: COVID-19 pandemic has led to more advanced-stage cancer diagnoses

Doctors who oversee cancer clinics say that new patients are arriving for treatment with more advanced disease than before the COVID-19 pandemic, according to a new survey from the American Society for Radiation Oncology.

UCLA receives grant to study the effectiveness of COVID-19 vaccines among health care workers

The David Geffen School of Medicine at UCLA has received a $4.9 million grant from the Centers for Disease Control and Prevention to study the effectiveness of COVID-19 vaccines among health care workers.

Imported COVID-19 cases responsible for spread of the UK and Brazil SARS-CoV-2 variants in Italy

A new study examines a major consequence of the second wave of COVID-19 infection—namely, the rapid emergence of new viral lineages and variants.

Single dose of Pfizer and Oxford vaccines shows 60% efficacy in elderly care home residents

A new study deals with the effect of two widely used vaccines in eliciting humoral immunity against the virus in this group. These are the Oxford/AstraZeneca viral-vectored vaccine (ChAdOx1 nCoV-19), and the Pfizer/BioNTech’s messenger RNA-based vaccine (BNT162b2). Both express the viral spike antigen, and both are currently being employed in the UK’s vaccination program.

Study finds rapid increase in IgG and IgA antibody levels following COVID-19 mRNA vaccination

A new study describes the kinetics of the antibody response to the earliest approved vaccines against COVID-19, which were developed on an mRNA platform.

Researchers report on novel SARS-CoV-2 Israeli strain with unique spike glycoprotein

Researchers from Israel describe a novel SARS-CoV-2 strain with a non-synonymous mutation in its spike glycoprotein, designated as P681H; nevertheless, its emergence has not been associated with increased infections rate, facilitated spread or vaccine evasion.

More people now willing to get vaccinated against SARS-CoV-2, study finds

The study, which appeared on the pre-print server medRxiv, aimed to examine the general public's willingness to receive COVID-19 vaccines and their safety concerns.

Scientists develop new method to estimate prevalence of SARS-CoV-2 antibodies

In the study, which appeared on the pre-print server medRxiv*, the team also modeled the pandemic phases with exponential growth and decay. The model improves upon maximum likelihood estimates by conditioning on more data.

Nanoparticles elicit neutralizing antibodies to diverse SARS-CoV-2 variants

Spike-protein-based nanoparticle vaccine candidates were retained longer in follicular dendritic cells and showed higher germinal center reactions in lymph node follicles compared to soluble spike protein vaccine.

Scientists study the sensitivity of SARS-CoV-2 variants to neutralize antibodies

The B.1.1.7 and B.1.351 variants of SARS-CoV-2 were first detected in the UK and South Africa respectively, and have since spread to many other countries.

Vaccine-induced 2C08 antibody protects against SARS-CoV-2 variants

A new preprint study posted to the bioRxiv* server led by Ali H. Ellebedy from the Washington University School of Medicine found that the monoclonal antibody 2C08 produced by the Pfizer vaccine could help neutralize COVID-19 variants.

Have scientists found SARS-CoV-2's Achilles' heel?

Have scientists uncovered the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Achille's heel? New preclinical research from Cell neutralizing antibodies targeting the N-terminal domain of the coronavirus could be a potential target for antibodies to bind and effectively neutralize SARS-CoV-2.

New study reports increased spread of B.1.1.7 variant in Houston, Texas

Research led by Jimmy Gollihar from the CCDC Army Research Laboratory-South in Austin, Texas found the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant B.1.1.7 —first detected last fall in England — increased in Houston, Texas. The B.1.1.7 variant is rapidly spreading with a case doubling time of 6.9 days.

Pfizer-BioNTech vaccine causes steep drop in COVID-19 among healthcare workers

A team of scientists from Spain has recently evaluated the efficacy of an mRNA-based COVID-19 vaccine developed by Pfizer-BioNTech (BNT162b2). Their findings reveal that a 2-dose regimen of BNT162b2 vaccine is capable of providing almost 100% protection against SARS-CoV-2 infection in healthcare workers.

Antibody for uterine sensitization associated gene-1 can stimulate tooth growth in mice

The tooth fairy is a welcome guest for any child who has lost a tooth. Not only will the fairy leave a small gift under the pillow, but the child can be assured of a new tooth in a few months. The same cannot be said of adults who have lost their teeth.

Researchers develop novel nanoadjuvant COVID-19 vaccine candidate

Researchers at the National Center for Nanoscience and Technology of China, the Chinese Academy of Sciences (CAS), introduced a new vaccine, which compromises the spike protein’s receptor-binding domain (RBD) and the manganese nanoadjuvant (MnARK), inducing humoral and cellular responses.
