Researchers outline characteristics of Omicron variant immune escape and viral entry into host cells

A new study found that the Omicron variant contains a number of mutations that decrease neutralizing antibody activity and immune escape.

Exploring a micro-simulation study on shielding individuals at high risk of COVID-19

A new study used an individual-based mathematical model to simulate the evolution of COVID-19 in a population, where a fraction of high-risk individuals is relocated to shielding residences having varying degrees of contact with others.

Comparison of neutralization of SARS-CoV-2 variants of concern Omicron and Delta

The purpose of this study was to determine the breadth of neutralizing activity generated by exposure to certain SARS-CoV-2 variants, vaccinations, or both.

Does SARS-CoV-2 Omicron variant elicited neutralizing immunity enhance that elicited by the Delta variant?

In this paper, researchers studied whether the neutralizing immunity produced by Omicron also increases neutralizing immunity of the Delta variant.

COVID boosters hinder SARS-CoV-2 Omicron

A new preprint research paper reports on the state of current knowledge as to the immune evasion capability of this variant, linking it to the type of vaccine used and the vaccination protocol.

Malta as a primer for rapid and effective COVID-19 vaccination strategy

A research paper recently published in the journal Health Sciences Review shows how high vaccine availability and low population vaccination hesitancy were two pivotal factors for the successful control of coronavirus disease 2019 (COVID-19) in Malta, Europe.

Scientists estimate transmission advantage of Omicron over Delta variant as +105%

Researchers use statistical models to assess the transmission of the SARS-CoV-2 Omicron using variant-specific screening tests and genome sequencing.

Study findings suggest spread of Omicron can be ascribed to immune evasiveness rather than an increase in transmissibility

Researchers investigate the household transmission of the Omicron VOC and increased immune evasiveness of both the Omicron and Delta variants

Exploring vaccine-induced cellular immunity against SARS-CoV-2 Omicron variant

In a new study, researchers determined CD8+ and CD4+ T cell responses against the SARS-CoV-2 Omicron variant in 51 individuals vaccinated with the messenger ribonucleic acid (mRNA)-based Pfizer and adenovirus vector-based Johnson & Johnson vaccines.

5 Jan 2022

Comparison of the mutational profile of Omicron with other SARS-CoV-2 lineages

Researchers from nference labs in Massachusetts have been examining the origins of a particular mutation in the Omicron variant.

COVID-19 mRNA vaccines offer protection against Omicron variant in pregnancy

A new study provides insights into the persistence of extra-neutralizing properties of mRNA vaccine-induced antibodies resulting in protection against the Omicron variant of SARS-CoV-2.

Oral bacteria-based SARS-CoV-2 vaccine platform

In a new study, researchers engineered the bacterial strain, Salmonella, to express differently-sized antigens to serve as vaccine platforms.

Can the COVID-19 delta variant evade vaccine-induced immunity?

Can the COVID-19 delta variant evade vaccine-induced immunity? We spoke to Professor Brian J. Willett from the University of Glasgow to find out.

5 Jan 2022

mRNA booster vaccine confers strong protection against SARS-CoV-2 Omicron in cancer patients

A new preprint research paper posted to the medRxiv* server reports the induction of high neutralizing activity in these patients against the Omicron VOC with a booster dose.

5 Jan 2022

Scientists provide a structural framework for Omicron immune evasion and ACE2 receptor recognition

An interesting preprint research paper describes structural changes resulting from the multiple mutations found in the recent Omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). SARS-CoV-2 is the causative agent behind the coronavirus disease 2019 (COVID-19) pandemic. In addition, the research describes the consequent effects of these changes on Omicron’s infectivity and immune evasion capabilities.

Transplant recipients benefit from a COVID-19 vaccine booster

A new preprint research paper posted to the medRxiv* server describes the reduction in humoral immunity in SOTR following vaccination, as well as the improvement with an additional dose of the vaccine.

New study on NAbs against SARS-CoV-2 Omicron variant after vaccination or infection

A recent study suggests neutralizing antibody responses against variants of concern, including Omicron, differs significantly between vaccinated and naturally infected individuals. The research, posted to the medRxiv* preprint server, focused on vaccinated individuals who are pregnant — an understudied group in COVID-19 research.

BNT162b2 provides low vaccine responders adequate anti-spike and neutralizing antibodies to prevent SARS-CoV-2

A new study, published on the medRxiv* preprint server, investigated the changes in SARS-CoV-2 antibody levels among HCWs after SARS-CoV-2 vaccination. The study also assessed whether low responders produced sufficient SARS-CoV-2 anti-spike and neutralizing antibodies.

4 Jan 2022

Efficacy of antibodies induced by natural infection, vaccination, or both against SARS-CoV-2 Omicron and Beta variants

A study has demonstrated that antibodies induced by two-dose COVID-19 vaccination or natural infection exhibit very low neutralizing activity against the omicron variant of SARS-CoV-2.

Characteristics and outcomes in patients hospitalized with COVID-19 in South Africa

A new research letter assessed patients hospitalized with a positive SARS-CoV-2 test during the fourth wave compared to the previous waves.
