Hospitalization and death associated with SARS-CoV-2 Omicron variant compared to Delta variant

Researchers evaluate the rates of hospitalization and deaths associated with the SARS-CoV-2 Omicron variant as compared to the Delta variant.

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.

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.

Statistical analysis reveals less severe COVID-19 outcome due to Omicron variant

A new study demonstrated that in the US, the COVID-19 cases arising after the emergence of the SARS-CoV-2 Omicron variant showed reduced severity of infection than in the cases recorded in previous time points (during the Delta variant outbreak).

5 Jan 2022

Efficacy of rapid antigen diagnostic tests for the detection of infectious individuals at mass gatherings

New study findings show that incidence data often underestimates the prevalence of COVID-19 infectious individuals at a given point in time in a population.

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.

Efficacy of COVID-19 convalescent plasma therapy in patients with hematological malignancies and COVID-19

Scientists recently demonstrated the efficacy of COVID-19 convalescent plasma therapy in improving the survival rate among patients with B-cell lymphoid malignancy and COVID-19.

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.

Nucleocapsid protein preferentially binds to structured and longer RNA to deliver viral proteins in host circulation

Results from a new study could be crucial in studying the molecular and biochemical basis of SARS-CoV-2 infection at a more granular level and help in strategizing therapeutic solutions to treat and manage COVID-19 effectively.

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.

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.

4 Jan 2022

Time since COVID vaccination is a key driver of breakthrough Omicron infections

Published on the preprint medRxiv* server and awaiting peer review, the findings showed that the significant factor behind breakthrough Omicron infections is the timing from vaccination. The time between vaccination and breakthrough infections induced effective or cross-reactive neutralizing antibodies that neutralize Omicron after Alpha or Delta breakthrough infections.

4 Jan 2022

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.

Novel insight into the immune characteristics of bats

Many studies have indicated that bats are significant reservoirs of innumerable viruses, such as influenza, coronaviruses, and rabies. These studies have also reported that bats predominantly remain asymptomatic or develop mild diseases during viral infections caused by henipaviruses, Ebola virus, coronaviruses, etc.

Birth during the pandemic associated with slightly lower scores in infants' motor and social skills

Columbia researchers found that babies born during the pandemic's first year scored lower on a developmental screening test of social and motor skills at 6 months - regardless of whether their mothers had COVID during pregnancy - compared to babies born just before the pandemic.

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

Both symptomatic and asymptomatic COVID-19 associated with increased risk of cardiovascular events

Researcers determine the risk of symptomatic and asymptomatic SARS-CoV-2 infection on post-acute cardiovascular events and all-cause mortality.

4 Jan 2022

Study finds no evidence to link in-person schooling and SARS-CoV-2 community incidence

A new study led by faculty at Binghamton University, State University of New York shows that COVID-19 incidence rates were not statistically different in counties with in-person learning versus remote school modes in most regions of the U.S.
