A reliable assessment of COVID-19 vaccine protection duration

Researchers from the University of North Carolina, University of Washington, and the US Food and Drug Administration propose fitting a Cox model with two time indexes, the event times measured from the start of the study in calendar time and the log hazard for the vaccine effect.

How much do mutations reduce vaccine effectiveness in the Omicron variant?

In new research, scientists from Adaptive Biotechnologies have been investigating the impact of spike protein mutations on vaccine efficiency for the Omicron variant. The study is currently available on the medRxiv* preprint server while awaiting peer review.

Loss of smell is the best predictor of COVID-19

A large international team of researchers has conducted a crowdsourced cross-sectional study, in which they have investigated the reliability of the olfactory loss (or loss of smell, or anosmia) as a predictor of coronavirus disease 19 (COVID-19).

Vaccine-induced T-cells vs. Omicron well preserved compared with all variants

A team of international scientists has recently revealed that T cell responses induced by coronavirus disease 2019 (COVID-19) vaccines are able to cross-recognize different variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The study is currently available on the bioRxiv* preprint server.

SARS-CoV-2 infection and immunity in pregnancy and fetal development

A review conducted by a team of researchers from the Icahn School of Medicine at Mount Sinai, the University of Colorado, and Active Motif, Incorporated compiles information on SARS-CoV-2 virology, in utero transmission from infected pregnant mothers to fetuses, new findings on possible methods of SARS-CoV-2 cellular trafficking through exosomes, and the transcriptomic effects of SARS-CoV-2 infection, in order to inform future studies aimed at a better understanding of COVID-19 and the development of therapeutic solutions against SARS-CoV-2.

Antibody neutralization of SARS-CoV-2 Omicron variant via BNT162b2 vaccine booster dose

New study findings highlight the need for a rapid booster vaccine campaign to prevent COVID-19 caused by the Omicron variant since the neutralization of Omicron by the two-dose BNT162b2 vaccine is not effective in controlling the spread of the infection.

Factors associated with SARS-CoV-2 breakthrough infection in fully vaccinated individuals

New study findings showed that the SARS-CoV-2 breakthrough infections are rare and show mild or asymptomatic profiles generally. The breakthrough infection occurs early after vaccination in almost 50% of the cases within 70 to 80 days post full vaccination.

Clinical-grade soluble human ACE2 shown to inhibit SARS-CoV-2 Omicron variant

New study findings show that the clinical-grade soluble ACE2 effectively inhibits the SARS-CoV-2 Omicron variant, which proves the principle of an effective therapeutic approach against Omicron-driven COVID-19 infections.

P323L mutations in SARS-CoV-2 are highly predictive of the emergence of new variants

In a new study, findings suggest that in some cases, tracking the distribution and frequency of SARS-CoV-2 minor variant genomes at a population level would help in predicting the emergence of a new dominant viral genome sequence.

Study shows varying population immunity against SARS-CoV-2

Researchers analyzed the combined distribution of COVID-19 vaccination and prior SARS-CoV-2 infection in each state and county in the US since the beginning of the COVID-19 epidemic to estimate the changes in the population immunity during this period.

Reviewing myocarditis and pericarditis in immunosuppressed individuals following COVID-19 mRNA vaccination

A new study did not conclusively correlate the incidence of myocarditis or pericarditis with mRNA vaccination against SARS-CoV-2.

Recombinant adjuvanted zoster vaccination associated with lower risk of COVID-19 diagnosis and hospitalization

A new study suggests that RZV may elicit durable innate immune responses in the elderly conferring heterologous protection against COVID-19. .

Study explores relative reproduction of the SARS-CoV-2 omicron variant in South Africa

A new study, focused on the SARS-CoV-2 Omicron variant, presented a modeling result from an analysis of genome surveillance data in Gauteng province, South Africa, using an existing estimation technique.

SUSU researchers identify biological indicators of long-lasting PTSD

War veterans have helped scientists of South Ural State University identify biological indicators which signal whether people have a post-traumatic stress disorder or a susceptibility to it.

SARS-CoV-2 infection can produce self-attacking autoantibodies

Infection with the virus that causes COVID-19 can trigger an immune response that lasts well beyond the initial infection and recovery - even among people who had mild symptoms or no symptoms at all, according to Cedars-Sinai investigators.

Booster doses of mRNA vaccines improve humoral immunogenicity in patients with inflammatory bowel disease

Researchers evaluated the humoral immunogenicity of a third COVID-19 mRNA vaccine dose in patients with inflammatory bowel disease.

Study uses metabolomics to discriminate drug-induced liver injury phenotypes

Drug-induced liver injury (DILI) is an adverse reaction to ingesting a drug, which can appear both in developmental stages, in their clinical use and even after being approved as a drug.

Orphanhood decreases with the availability of antiretroviral therapy and male circumcision

Researchers at Columbia University Mailman School of Public Health found marked decreases in orphanhood particularly double orphanhood, among adolescents in Rakai, Uganda, corresponding with the availability of antiretroviral therapy (ART) beginning in 2004 and of male medical circumcision in 2007.

Once-a-day antiretroviral medicine for children proven to be more effective at suppressing HIV

A once-a-day antiretroviral medicine that is low-cost and easy for children to take is also more effective at suppressing HIV than standard treatments, according to a global trial led by researchers at UCL.

Growth-friendly surgeries have more complications than spinal fusion in kids treated with severe scoliosis

A Michigan Medicine study found that preadolescent children with severe neuromuscular scoliosis who are treated with growth-friendly surgery prior to spinal fusion have more complications and unplanned subsequent surgeries than those who only have the spinal fusion.
