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.

Vaccinated kidney transplant recipients not adequately protected against emerging SARS-CoV-2 variants

Kidney transplant recipients tend to mount impaired antibody responses against emerging SARS-CoV-2 variants after standard two-dose COVID-19 vaccination, according to new research published in CJASN.

Ad5-nCoV vaccine safe and effective against symptomatic, severe COVID-19, trials shows

One dose of Ad5-nCoV (Convidecia), a COVID-19 vaccine developed in China, is 57.5% effective against symptomatic COVID-19 and 91.7% effective against severe COVID-19 disease beginning 28 days postvaccination, according to a phase 3 randomized controlled trial published in The Lancet.

Researchers identify a key influenza epitope that can targeted for developing universal vaccines

A team led by scientists at Weill Cornell Medicine, Scripps Research and the University of Chicago has identified an important site of vulnerability on influenza viruses—a site that future influenza vaccines and antibody therapies should be able to target to prevent or treat infections by a broad set of influenza strains.

Children produce a much more robust antibody response to a SARS-CoV-2 infection than 18+

Scientists compared receptor binding domain antibodies and SARS-CoV-2 neutralizing antibodies in children and adults.

Omicron has enhanced infectivity that is only weakly neutralized by vaccination or prior infection

Scientists used virus-like particles and found that Omicron showed increased infectivity, relative to the B.1 and B.1.1 strains, which was similar to the Delta variant.

Researchers report loss of antibody potency against SARS-CoV-2 Omicron variant

Researchers find that vaccine-mediated protection against SARS-CoV-2 is significantly reduced against the Omicron variant.

Exploring immunity and severe disease caused by the SARS-CoV-2 Omicron variant

A new study describes the findings of a seroprevalence survey intended to establish the infection rates and the incidence of severe COVID-19 through December 15, 2021, in Gauteng, a crowded province that compresses a quarter of the country’s people into less than 2% of its area.

23 Dec 2021

Study reports that children develop sustained cross-reactive adaptive immunity against coronaviruses

A new study shows that both antibody and cellular arms of the adaptive immune response against SARS-CoV-2 are displayed strong, sustained, and cross-reactive against other coronaviruses, in young children than the immune responses in adults.

T-cell response to Omicron after an mRNA COVID vaccine booster

In a recent prospective observational study posted to the medRxiv* preprint server, researchers determined Omicron variant-associated T cell responses before and after a third dose of messenger ribonucleic acid (mRNA) vaccination against coronavirus disease (COVID-19) in anti-CD20-treated multiple sclerosis (MS) patients.

rVSV-based bivalent vaccine against SARS-CoV-2 delta variant and influenza

Researchers developed four distinct recombinant vesicular stomatitis virus (rVSV)-based bivalent vaccines against SARS-CoV-2 and influenza virus.

Study confirms coronavirus RNA synthesis occurs inside membrane-bound compartments

Researchers have experimentally proved that virus-related double-stranded RNA (dsRNA) and the sites of viral RNA synthesis are associated with one another.

Importance of booster vaccine doses for maintaining protection against the SARS-CoV-2 Omicron variant

A new study shows that although the Omicron variant exhibits significant immune escape compared to other SARS-CoV-2 variants, antibody neutralization can be largely restored with booster doses of mRNA vaccines.

22 Dec 2021

Extended interval between second and third vaccination beneficial against SARS-CoV-2 Omicron variant

A new study proposes a multi-boost vaccine strategy with a longer duration between the second and third dose, as that would be beneficial in acquiring immunity against severely mutated SARS-CoV-2 variants.

Two-dose ChAdOx1 vaccine protection wanes after three months

New research reported in the journal The Lancet examines the temporal association between the two-dose ChAdOx1 nCoV-19 (Oxford-AstraZeneca) vaccination regimen and the risk of severe outcomes from COVID-19 in Scotland vs. Brazil, where the Delta variant of SARS-CoV-2 was dominant and rare, respectively.
