An antibody is a blood protein that is produced in response to and counteracts an antigen. Antibodies are produced in response to disease and help the body fight against the particular disease. In this way, antibodies help the body develop an immunity to disease.

Study shows lower antibody cross-reactivity after infection with the B.1.1.7 SARS-CoV-2 variant

In a recent research paper currently available on the bioRxiv* preprint server, a diverse group of researchers has examined the immunogenicity of antibodies against the variant B.1.1.7 of the severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) initially found in the United Kingdom – and revealed diminished recognition and neutralization of either parental strains or the South African variant.

Results from phase 2 trial of Novavax recombinant nanoparticle SARS-CoV-2 vaccine

Novavax, Inc., the American vaccine development company, has been developing a recombinant protein nanoparticle COVID-19 vaccine currently termed NVX-CoV2373. The full-length spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is created in a baculovirus vector, which is then inserted into a lipid nanoparticle around 50 nm in diameter.

Pfizer SARS-CoV-2 vaccine effective from day 11 post 1st vaccination

New research from a team of scientists in Australia finds that the second ‘booster’ dose of the Pfizer-BioNTech vaccine did not increase vaccine efficacy against severe acute respiratory syndrome (SARS-CoV-2), the causative agent of coronavirus disease 2019 (COVID-19). The results suggest one dose of the vaccine was sufficient in providing a robust immune response 11 days after inoculation.

Researchers to investigate COVID-19's disproportionate impact on long-term care residents and workers

Long-term care facilities have been disproportionately burdened by COVID-19, accounting for about 60% of COVID-19 deaths nationwide, 70% if retirement homes are included.

Research shows a causal relationship between neonatal antibody production and maternal microbiota

A healthy system of gut bacteria, or microbiota, is crucial to health: Gut bacteria not only aid with digestion, but also play an important role in the body's immune response. Infants, however, are not born with full-fledged gut microbiota, which makes it difficult for them to fight off intestinal infections.

Vaccine candidate shows promise to protect against dozen-plus flu strains

Ask Eric Weaver about pandemics, and he's quick to remind you of a fact that illustrates the fleeting nature of human memory and the proximal nature of human attention: The first pandemic of the 21st century struck not in 2019, but 2009.

Researchers develop ultrapotent miniproteins that target SARS-CoV-2 receptor-binding domain

Researchers have investigated the effectiveness of a bioengineered miniprotein in protecting against SARS-CoV-2 infection in vivo. The researchers evaluated the miniprotein, LCB1, against SARS-CoV-2-mediated lung disease in human ACE2-expressing transgenic mice.

Obesity may reduce COVID-19 vaccine efficacy, say researchers

A startling indicates that obesity may reduce the immune response to the current COVID-19 vaccines, along with other factors like age and sex. This could have significant implications for vaccination strategies in obese people.

Researchers examine long-term immune responses following COVID-19 across clinically diverse cohort

A new study by researchers at the University of California, San Francisco, discusses the different aspects of long-term immune responses in a wide sample of patients, as well as how they vary in clinical severity and sequelae.

Novel SARS-CoV-2 spike vaccine candidate produces strong neutralizing response in vivo

A new study by researchers at Mahidol University in Bangkok, Thailand, reports a COVID-19 vaccine candidate called HexaPro in producing neutralizing antibodies against the SARS-CoV-2 spike protein in an animal model.

SARS-CoV-2 viremia predicts severe COVID-19 disease outcomes

The SARS-CoV-2 plasma viremia has been linked to severe disease and death in COVID-19 cases in small-scale cohort studies. The current study, published on the pre-print server medRxiv, aimed to study the mechanisms behind this relationship.

Early antibody response predicts COVID-19 outcome

To address this gap, researchers from the U.S. evaluated the timing of antibody production against SARS-CoV-2 in hospitalized patients. They used a highly sensitive multiplexed bead-based immunoassay that allows for early detection of anti-SARS-CoV-2 antibodies. The study is published on the preprint server medRxiv.

Concerning mutation in New York SARS-CoV-2 should be monitored, warn researchers

Researchers at the New York State Department of Health in the United States have said concerning mutations within the B.1.526 lineage of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that has recently become prevalent in New York State warrant further monitoring.

Survey reveals impact of Pfizer-BioNTech vaccination in the UK

Researchers at Imperial College London in the UK have reported on round five of the REal-time Assessment of Community Transmission-2 (REACT-2) program – a cross-sectional community survey measuring the prevalence of antibodies against the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) among adults in England.

New computer algorithm offers a path toward pan-influenza and coronavirus vaccine

A novel computer algorithm that could create a broadly reactive influenza vaccine for swine flu also offers a path toward a pan-influenza vaccine and possibly a pan-coronavirus vaccine as well, according to a new paper published in Nature Communications.

Children with MIS-C have highly activated immune systems, study finds

Taking the first deep dive into how the immune system is behaving in patients with multisystem inflammatory syndrome in children (MIS-C), researchers at Children's Hospital of Philadelphia and the Perelman School of Medicine at the University of Pennsylvania have found that children with this condition have highly activated immune systems that, in many ways, are more similar to those of adults with severe COVID-19.

Could small synthetic antigen proteins be diagnostic tools for SARS-CoV-2?

Researchers have developed small proteins from sequences in SARS-CoV-2's RBD that bind to ACE2. These were as effective in binding to neutralizing antibodies as larger RBD proteins.

SARS-CoV-2 UK variant shows low virulence and high shedding in hamster model

A new study compares the pathogenicity and infectiousness of one such variant, the VOC 202012/01 (B.1.1.7 lineage) from the United Kingdom, with the globally dominant D614G mutation-carrying strains.

Studies reveal the promise of newly engineered bispecific antibodies against tumor cells

Three studies - one each in Science, Science Translational Medicine, and Science Immunology - reveal the promise of newly engineered bispecific antibodies, including by demonstrating their power against previously inaccessible tumor cell targets for the first time, in two cases.
