Evaluation of SARS-CoV-2 Omicron's immune evasion potential

Researchers use VSV vector and Omicron spike protein containing all 32 mutations to create the pseudotyped SARS-CoV-2 Omicron variant (PV-Omicron).

Signatures of rising SARS-CoV-2 Delta infections in New York

Researchers estimate the probability of breakthrough infections by the Delta variant as compared to other variants.

Weak T-cell clonal response to SARS-CoV-2 vaccination in IBD patients deficient in antibody-responders

Researchers investigate the post-vaccination clonal T-cell response and its relationship to antibody responses in IBD patients.

T-cell immune response in previously infected and vaccinated individuals effective against SARS-CoV-2 Omicron variant

New findings illustrate that despite the continuous pattern of the ongoing evolution of SARS-CoV-2, it has not resulted in any significant accumulation of CD8+ T-cell escape mutations.

Exploring the possibility of developing a plant-based oral vaccine against COVID-19

New research optimizes methods for the in-planta expression of the recombinant protein corresponding to the Receptor Binding Domain (RBD) subunit of the surface-exposed Spike glycoprotein of SARS-CoV-2.

Persistence of symptoms up to a year after hospitalization for COVID-19

Researchers conducted a prospective cohort study to determine the persisting COVID-19 associated symptoms after hospitalization and their risk factors.

West African countries must increase COVID-19 vaccination rates to achieve population-level immunity

West African nations need to drastically ramp up their COVID-19 vaccination programmes by factor of 10 if they are to reach at least 60% coverage by 2022 and achieve the population level immunity needed to bring the pandemic under control in Africa and elsewhere, indicates an analysis published in the open access journal BMJ Global Health.

Cell surface expression of SARS-CoV-2 nucleocapsid protein and its role in immunity

Researchers demonstrated the unexpected roles of nucleocapsid protein in innate and adaptive immunity to SARS-CoV-2.

Trajectory of SARS-CoV-2 vaccination and immunity examined in new model

Researchers have created a model of looking at the spread of COVID-19 that takes both vaccination rates and rates of loss of immunity into account and can be adjusted as factors change.

Monoclonal antibody activity against SARS-CoV-2 Omicron variant

Scientists from Germany have recently pointed out that the third booster dose of mRNA-based COVID-19 vaccine is highly effective in neutralizing the omicron variant of SARS-CoV-2.

Containing a Nipah virus outbreak amidst the COVID-19 pandemic

A new study deals with a single case of Nipah virus that occurred in 2021, with no discoverable chain of transmission, apparently ending with the death of the index patient in Kerala.

How fast has the Omicron strain been spreading in South Africa?

Scientists have shown the exponential growth of the Omicron strain found in Gauteng. They reported the doubling time of this strain to be equal to 3.38 days by analyzing its growth from November 8 to December 5, 2021. Based on the mutation accumulation profile, researchers revealed that this strain began to diverge between October 28 and November 5, 2021.
