Frequent testing improves the detection of SARS-CoV-2

Detecting SARS-CoV-2, the virus that causes COVID-19, improves with regularity of testing, whether using rapid antigen tests or PCR molecular tests

Frequent testing increases chance of detecting COVID-19 infections

The chance of detecting the virus that causes COVID-19 increases with more frequent testing, no matter the type of test, a new study found. Both polymerase chain reaction and antigen tests, paired with rapid results reporting, can achieve 98% sensitivity if deployed at least every three days.

Study shows SARS-CoV-2 breakthrough infections fewer among fully vaccinated

A team of researchers at Indiana University reports genomic evidence of breakthrough infections in fully vaccinated individuals. The study, posted to the pre-print server medRxiv*, suggests that fully vaccinated individuals, including those with asymptomatic infections, are less likely to serve as a source of infection for others.

Widespread SARS-CoV-2 mutation escapes vaccine- and infection-induced CD8 T-cell responses

Researchers in the UK have warned that a widespread mutation that has arisen in the spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) appears to escape recognition by CD8 T-cell responses in both convalescent patients and recipients of the current coronavirus disease 2019 (COVID-19) vaccines.

Innovative corona test offers great potential for systematic testing

A new corona test developed at the University Hospital Bonn can analyze a large number of swabs simultaneously using sequencing technology and has a similarly high sensitivity as the common qPCR test.

Tackling emerging SARS-CoV-2 variants

An international team of authors has published a special report in The New England Journal of Medicine titled 'SARS-CoV-2 Variants and Vaccines’, which presents global strategies for the possible escape from vaccine-elicited immunity.

SARS-CoV-2 test in 20 minutes with FISH

A collaboration from the University of Oxford and the University of Warwick has led to research into a novel method of viral detection through rapid fluorescence in situ hybridization (FISH) in order to effectively detect the SARS-CoV-2 virus within 20 minutes.

What's behind COVID-19 vaccine side effects?

A growing concern among coronavirus vaccines is the vaccine side effects. Fear or misinformation about side effects may fuel vaccine hesitancy, contributing to low vaccination rates. Australian researchers recently published an article in Science Immunology to discuss why people develop side effects and their benefits.

Specific lung cell exhibits immune properties and improves respiratory viral disease outcomes

Researchers at Children's Hospital of Philadelphia have discovered that a specific type of lung cell exhibits unconventional immune properties and may contribute to the outcome of respiratory viral infections.

Could the activation of FcγRIII/CD16 by anti-spike SARS-CoV-2 antibodies independently determine COVID-19 severity?

A team of scientists from Germany recently investigated whether hyperactivation of immune receptors that recognize the Fc part of an IgG molecule (FcγR) can lead to immunopathologic changes in coronavirus disease 2019 (COVID-19) patients. They have observed that hyperactivation of FcγRIII (CD16) by proinflammatory IgG antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can significantly contribute to COVID-19 related immunopathology.

Novel face mask can diagnose Covid-19 in 90 minutes

Engineers at MIT and Harvard University have designed a novel face mask that can diagnose the wearer with Covid-19 within about 90 minutes. The masks are embedded with tiny, disposable sensors that can be fitted into other face masks and could also be adapted to detect other viruses.

Gene variant in African Americans contributes to unnecessary bone marrow biopsies

A gene variant that lowers white blood cell levels and is common in individuals with African ancestry contributes to unnecessary bone marrow biopsies, according to a study published June 28 in JAMA Internal Medicine.

Study associates higher antibody titers with naïve B cells post-mRNA vaccination

Researchers compared peripheral blood mononuclear cells in people with high and low antibody titers after two doses of the Pfizer/BioNTech (BNT162b2) mRNA vaccine. They found a positive correlation between naïve B cells present before vaccination and high antibody titers.

Study finds minimal SARS-CoV-2 viral load in vaginal secretions

The virus has also been observed to be present in blood, urine, feces, and tears, though not in semen. Vaginal secretions have not been consistently shown to be positive for the virus in most studies. The authors of a new study in the Journal of Clinical Medicine affirm that the presence of the virus in the vagina is rare, irrespective of pregnancy.

Vaccines and drugs must be adapted to combat emerging SARS-CoV-2 variants, says study

A new review of the emerging variants of concern (VOCs) of the SARS-CoV-2, which has caused the COVID-19 pandemic, shows that there is a major need to constantly re-evaluate the utility of existing therapeutics and vaccines against the virus and to develop new ones.

Promising immunotherapy uses cancer-killing cells to destroy malignant tumors

Researchers at McMaster University have developed a promising new cancer immunotherapy that uses cancer-killing cells genetically engineered outside the body to find and destroy malignant tumors.

Study explores the potential role of gene polymorphisms in pathogenesis of prostate cancer

Oncotarget published "The presence of polymorphisms in genes controlling neurotransmitter metabolism and disease prognosis in patients with prostate cancer: a possible link with schizophrenia" reported that polymorphisms of neurotransmitter metabolism genes were studied in patients with prostate cancer (PC) characterized by either reduced or extended serum prostate-specific antigen doubling time corresponding to unfavorable and favorable disease prognosis respectively.

An affordable, scalable and highly sensitive virus-genome-based testing approach

Aiming to reduce human suffering, economic costs, and restrictions on personal freedom caused by COVID-19 to a minimum, researchers from Germany and Austria proposed an alternative method - efficient population-based genome-based testing.

Oxford-AstraZeneca COVID-19 vaccine induces robust T cell-based immunity

A recent study conducted by an international team of scientists has revealed that the Oxford-AstraZeneca coronavirus disease 2019 (COVID-19) vaccine, AZD1222, is capable of inducing strong spike-specific CD4+ T cell helper type 1 (Th1) and CD8+ T-cell responses in vaccinated individuals. A detailed description of AZD1222-induced cellular immunity is currently available on the medRxiv* preprint server.
