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.

6 Jan 2022

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.

6 Jan 2022

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.

6 Jan 2022

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.

6 Jan 2022

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.

5 Jan 2022

Booster dose elicits cross-reactive humoral immunity against SARS-CoV-2 Delta and Omicron variants

Researchers determine the cross-reactivity of the SARS-CoV-2 spike glycoprotein-induced antibodies before and after a third SARS-CoV-2 vaccine dose.

5 Jan 2022

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

5 Jan 2022
