Scientists study how our immune system responds to COVID-19 variants

Australian scientists researching how our immune system responds to COVID-19 have revealed that those infected by early variants in 2020 produced sustained antibodies, however, these antibodies are not as effective against contemporary variants of the virus.

New biological pathway selectively controls how key immune cells mature into functional components

Immunologists at St. Jude Children's Research Hospital have identified a biological pathway that selectively controls how key immune cells, called T follicular helper cells, mature into functional components of the immune system.

B.1.1.7 variant of SARS-CoV-2 is more transmissible than B.1.526

A new paper available on the medRxiv* preprint server presents evidence that the B.1.1.7 VOC is more transmissible than the B.1.526 strain.

B.1.427/B.1.429 variant of SARS-CoV-2 evades neutralization via disulfide bond rearrangement

A new paper discusses an intriguing new mechanism of immune evasion traceable to specific mutations in the B.1.427/B.1.429 variant of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Molecular imaging can improve therapeutic management of pancreatic ductal adenocarcinomas

For patients with pancreatic ductal adenocarcinomas (PDAC), molecular imaging can improve staging and clinical management of the disease, according to research published in the June issue of The Journal of Nuclear Medicine.

Can memory T cell responses to seasonal coronaviruses protect against severe COVID-19?

In a recent study published in the journal Science Immunology, scientists have revealed that the presence of CD8+ T cells against conserved epitopes of seasonal coronaviruses is associated with mild coronavirus disease 2019 (COVID-19). These immune cells exhibit a memory phenotype and provide protection against severe disease.

New study reports low SARS-CoV-2 breakthrough infections in vaccinated healthcare workers

Researchers examined cases of SARS-CoV-2 infection in fully and partially vaccinated healthcare workers, finding that vaccination provided strong immunity to the virus even though VOCs are on the rise in the non-vaccinated community at large.

Will the US’s COVID-19 vaccination campaign be undermined by novel SARS-CoV-2 variants of concern?

New research from Arizona State University, USA, uses a novel mathematical model to predict the impact of vaccination and vaccine-induced cross-protection on the B.1.1.7 variant and other SARS-CoV-2 variants circulating in the US as of June 2021. The study has been published in medRxiv* preprint server, while it undergoes peer review.

California’s highest covid infection rates shift to rural counties

Most of us are familiar with the good news: In recent weeks, rates of covid-19 infection and death have plummeted in California, falling to levels not seen since the early days of the pandemic.

As covid vaccinations slow, parts of the US remain far behind 70% goal

July Fourth was not the celebration President Joe Biden had hoped for, as far as protecting more Americans with a coronavirus vaccine.

Study shows antibody titers after natural SARS-CoV-2 infection last longer than previously thought

A recent study by researchers from the United Kingdom (UK) revealed that antibody levels associated with protection against reinfection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are likely to last from 1.5 to 2 years on average and that the protection from severe infection may be present for several years.

Moderna’s COVID-19 vaccine elicits durable T cell memory and antibody responses

Researchers in the United States have shown that Moderna’s mRNA-1273 coronavirus disease 2019 (COVID-19) vaccine induces durable antibody and T cell responses to the spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that are comparable to those seen in cases of COVID-19 caused by natural SARS-CoV-2 infection.

New method expands view into activity of single cells

Researchers have devised a way to multiply by more than ten-fold the accessible details of gene activity in individual cells. It's a big leap in the effort to understand cancer development, brain function, immunity and other biological processes driven by the complex interactions of multitudes of different cell types.

COVID-19 recovered vaccinated individuals more protected from Delta variant

The B.1.617 lineage of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), first detected in October 2020, has led to new outbreaks of the infection and new waves of the pandemic. This infectious lineage has resulted in the generation of sub-lineages such as B.1.617.1 (Kappa), B.1.617.2 (Delta) and B.1.617.3.

Study says mRNA COVID vaccines are effective against Lambda variant

Researchers in the United States have conducted a study suggesting that the coronavirus disease 2019 (COVID-19) vaccines that are currently being rolled out in many countries should be effective against the C.37 lineage (lambda variant) of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

5 Jul 2021

Scientists identify breakthrough cases of SARS-CoV-2’s delta variant in fully vaccinated individuals

In a recent study conducted at the Baylor College of Medicine, Houston, USA, scientists have identified six vaccine breakthrough cases caused by the delta variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
