Evaluating immune protection after third and fourth doses of homologous and heterologous SARS-CoV-2 vaccines among kidney transplant recipients

Researchers evaluated the immune responses after the third and fourth doses of homologous and heterologous mRNA vaccines against COVID-19 in kidney transplant recipients.

How protection due to vaccination or previous SARS-CoV-2 infection varies for the population of the Czech Republic

The current study aimed to understand how far this reduced vaccine efficacy and the protection conferred by prior infection in terms of Omicron infection, hospitalization, and oxygen supplementation.

Researchers reveal the mechanism of action of century-old BCG vaccine

The century-old Bacille Calmette-Guérin (BCG) vaccine against tuberculosis is one of the world's oldest and most widely used vaccines, used to immunize 100 million newborns every year. Given in countries with endemic TB, it has surprisingly been found to protect newborns and young infants against multiple bacterial and viral infections unrelated to TB. There's even some evidence that it can reduce severity of COVID-19.

SARS-CoV-2 infection during pregnancy linked to adverse maternal outcomes and preterm birth

Since the coronavirus disease 2019 (COVID-19) pandemic was declared in 2020, there has been much concern over the effects of the disease on unborn children and pregnant women.

Injectable hydrogels for single-dose COVID-19 vaccination

Several coronavirus disease 2019 (COVID-19) vaccines require multiple doses for long-lasting immunity. However, a new study published in the journal Biomacromolecules has developed a promising single-dose vaccine platform using an injectable hydrogel containing an epitope-labeled plant virus, Cowpea mosaic virus (CPMV).

SARS-CoV-2 BA.2 poses greater risk to global health than BA.1

In a recent study published in the journal Cell, researchers investigated distinguishing virological characteristics of Omicron sub-variant BA.2.

Study reveals trends in clinical characteristics and outcomes of STEMI patients with COVID-19

A newly published analysis in the Journal of the American College of Cardiology1 of hospitalized patients with both a severe type of heart attack called STEMI (ST-elevation myocardial infarction) and coronavirus disease-19 (COVID-19) infection compares clinical outcomes for these patients during the first and second years of the COVID-19 pandemic.

CDC reports U.S. case of human avian influenza A(H5) virus

A person has tested positive for avian influenza A(H5) virus (H5 bird flu) in the U.S., as reported by Colorado and confirmed by CDC.

Study explores SARS-CoV-2 RNA genome's functional interactions with host cell

In a new study, a worldwide map of the SARS-CoV-2 genome-associated host proteins was developed by a team of researchers using the identification of RNA-binding protein by MS (ChIRP-MS) technique.

Multivalent messenger ribonucleic acid-lipid nanoparticle vaccines against SARS-CoV-2

A new study analyzed multivalent messenger ribonucleic acid (mRNA)-lipid nanoparticle (LNP) vaccine constructs against certain β-coronaviruses (β-CoVs).

Needle- and adjuvant-free vaccination with non-infectious T4-COVID nanoparticles induces strong immunity in mice

Researchers developed a mucosal vaccine for COVID-19 based on bacteriophage.

3 May 2022

Study reveals Omicron sub-lineages BA.4 and BA.5 escape neutralizing antibodies elicited in response to BA.1 infection

Researchers evaluated whether neutralizing immunity elicited against Omicron sub-variant BA.1 in unvaccinated and vaccinated individuals adequately protected against infection by Omicron sub-variants, BA.4 and BA.5.

3 May 2022

Effectiveness of ChAdOx1-S COVID-19 booster vaccine

Researchers assessed the effectiveness of ChAdOx1-S COVID-19 booster vaccination.

3 May 2022

Study suggests aerosol transmission of antibodies may contribute to host protection against SARS-CoV-2

A new study has addressed the previously mentioned research gap and has investigated the possibility of transfer of aerosol containing SARS-CoV-2-specific antibodies between vaccinated and non-immune hosts

Epidemiologic and genomic investigation of SARS-CoV-2 infections associated with two repatriation flights from India to Australia

Researchers conducted epidemiologic and genomic studies to investigate in-flight SARS-CoV-2 infection associated with repatriation flights from India to Australia in April 2021.

3 May 2022

Prior SARS-CoV-2 infection provides substantial and sustained protection from Omicron hospitalization

A population-level study conducted on residents of the Quebec province, Canada, has demonstrated that prior infection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) induces robust and long-lasting protection against omicron re-infection and hospitalization. The level of protection further increases with coronavirus disease 2019 (COVID-19) vaccination.

Schools' role in the spread of SARS-CoV-2

The Omicron wave of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)––the causative pathogen for coronavirus disease 2019 (COVID-19) and the current pandemic––led to rampant transmissions in schools. Therefore, the school-based viral transmission must be curtailed to reduce viral evolution and maintain children's in-person education.

Antibiotics may disrupt microbiome to cause recurrent UTIs

A study by researchers at Washington University School of Medicine in St. Louis and the Broad Institute of MIT and Harvard suggests that women who get recurrent urinary tract infections (UTIs) may be caught in a vicious cycle in which antibiotics given to eradicate one infection predispose them to develop another.

Online misinformation negatively impacts COVID-19 vaccination campaign, study shows

Online misinformation has negatively impacted the US COVID-19 vaccination campaign. This emerges from a study by Francesco Pierri, researcher at the Politecnico di Milano, in collaboration with Indiana University as part of the H2020 Periscope project, published in Nature Scientific Reports.

P681 mutations in SARS-CoV-2 spike protein determine fusogenicity

Researchers evaluated the importance of the P681 residue within the furin cleavage site of SARS-CoV-2 spike protein in determining the fusogenicity and syncytia formation ability of SARS-CoV-2 strains.
