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.

Fecal transplant and fiber supplementation can benefit patients with obesity-related metabolic syndrome

A transplant of healthy gut microbes followed by fiber supplements benefits patients with severe obesity and metabolic syndrome, according to University of Alberta clinical trial findings published today in Nature Medicine.

Research team identifies a way to improve immune response during viral infections

Melbourne researchers have identified a way to improve the immune response in the face of severe viral infections.

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.

Two chemoattenuated PfSPZ malaria vaccines provide strong and lasting protection

A team of researchers recently optimized regimens for CVac, wherein aseptic, purified, cryopreserved, and infectious PfSPZ were inoculated and mixed with PYR and CQ.

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).

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).

Varenicline blocks SARS-CoV-2 infection in cells and animal models

A new paper released on the bioRxiv* preprint server suggests that the nicotinic acetylcholine receptor (nACHR) agonist, varenicline tartrate, has antiviral activity against the virus.

Exposure to beneficial microorganisms is not affected by targeted hygiene or cleaning

The theory that modern society is too clean, leading to defective immune systems in children, should be swept under the carpet, according to a new study by researchers at UCL and the London School of Hygiene & Tropical Medicine.

Scientists identify natural SARS-CoV-2 super immunity against 23 variants

The antibodies are capable of neutralizing a wide range of SARS-CoV-2 variants even at sub-nanomolar concentrations. In addition, the combinations of these antibodies reduce the risk of generating escape mutants in vitro. The study is published in the journal Science.

Rapid quantification of SARS-CoV-2 Spike-specific T cells by direct peptide stimulation of whole peripheral blood

To understand both the correlates of protection induced by vaccinations and the necessary immune responses to manage the COVID-19, researchers from Singapore used an alternative method to closely evaluate the kinetics and magnitude of specific T cell responses to SARS-CoV-2 infection. Their work was posted to the bioRxiv* preprint server while awaiting peer review.

Janssens’ COVID-19 vaccine effective against SARS-CoV-2 Delta variant

Researchers in the Netherlands have conducted a study showing that Janssen’s Ad26.COV2.S coronavirus disease 2019 (COVID‐19) vaccine was effective against variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) among eight individuals.

COVID-19 vaccination induces highly variable immunity among the immunocompromised

Researchers in the United States have conducted a study showing that the humoral (antibody) immunity induced by vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19) – varies significantly among immunocompromised individuals.
