New trial evaluates Omicron BA.1–adapted BNT162b2 vaccine in older adults

Researchers reported the findings of the phase III trial evaluating the Omicron BA.1–adapted mono and bivalent BNT162b2 coronavirus disease 2019 (COVID-19) vaccine in 55-year-old adults. These individuals had already received three 30μg doses of the BNT162b2 vaccine.

Study finds fewer cases of MIS-C during omicron wave of the pandemic than delta

A new University at Buffalo study conducted at John R. Oishei Children's Hospital is one of the first to reveal that there were fewer cases of multi-system inflammatory syndrome in children (MIS-C) during the omicron wave of the pandemic than the delta wave.

Exploring the infectivity, transmissibility, and immunological resistance characteristics of SARS-CoV-2 Omicron XBB.1.5 strain

Researchers performed an epidemic dynamic analysis to assess the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant of concern (VOC)’s sub-VOC XBB.1.5 characteristics.

How do mutations in emergent SARS-CoV-2 Omicron variants affect viral function, human immunity, and recognition by therapeutic antibodies?

Researchers explored how mutations in emergent SARS-CoV-2 variants affect viral function, human immunity, and recognition by therapeutic antibodies.

T-cell immunity and antibody responses against SARS-CoV-2 among individuals registered in the Bangkok home health care service

Researchers performed an observational study among COVID-19 patients and their close contacts registered with the Bangkok home health care services in Thailand.

18 Jan 2023

Epitope mapping reveals the humoral responses against the main SARS-CoV-2 structural proteins in infected patients from Africa

Researchers performed immunoglobulin (Ig)M and IgG epitope mapping against 487 SARS-CoV-2 peptides.

18 Jan 2023

Tight transmission bottlenecks may limit the evolution of SARS-CoV-2 variants

A new study describes that tight transmission bottlenecks restrict the evolution of SARS-CoV-2 in the transmission chain. SARS-CoV-2 is the causative pathogen of the COVID-19 pandemic.

18 Jan 2023

Exploring a novel amplicon-based mpox virus sequencing strategy

Researchers described the development of a sequencing strategy based on amplicons for mpox detection.

18 Jan 2023

What older Americans need to know about taking Paxlovid

A new coronavirus variant is circulating, the most transmissible one yet. Hospitalizations of infected patients are rising. And older adults represent nearly 90% of U.S. deaths from covid-19 in recent months, the largest portion since the start of the pandemic.

18 Jan 2023

The "Great Escape" by SARS-CoV-2 XBB.1

In a recent article published in the Lancet Microbe, researchers in the Netherlands and the United Kingdom quantified the antigenic diversity of new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) subvariants, BQ.1.1, BM.1.1.1, and XBB.1, all derivatives of the variant of concern (VOC) Omicron, which emerged in late 2022.

On four flights out of China in December, 22% of passengers were SARS-CoV-2 positive

Researchers document COVID-19 screening results in Italy of 556 flight passengers from two Chinese provinces in late December 2022.

17 Jan 2023

What are the major findings of long COVID research?

Researchers explored existing literature on long coronavirus disease (COVID). They highlighted key immunological findings, similarities with other diseases, symptoms, and associated pathophysiological mechanisms, and diagnostic and therapeutic options, including COVID-19 vaccinations.

17 Jan 2023

Exploring bioinformatics approach for evaluating binding affinities of probable COVID-19 therapeutic decoys

Researchers developed a computational workflow based on molecular dynamic (MD) simulations and artificial neural network (ANN) to assess the SARS-CoV-2 spike (S) protein receptor-binding domain (RBD)-human angiotensin-converting enzyme 2 (hACE2) binding affinities of SARS-CoV-2 variants.

17 Jan 2023

Study finds non-Omicron breakthrough infections elicit robust cross-neutralizing activity against Omicron variants across the antigenic barrier

Researchers assessed the effect of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection with a non-Omicron variant on SARS-CoV-2 BA.4/5 neutralization.

17 Jan 2023

Overall patterns of SARS-CoV-2 caused by variants of concern among children and adolescents

A recent study systematically reviewed COVID-19 among adolescents and children due to SARS-CoV-2 variants of concern.
