Ongoing testing of immunized individuals will be key to mitigate future COVID-19 outbreaks

In rare cases, people who have been fully vaccinated against COVID and are immune to the virus can nevertheless develop the disease.

Striking difference identified between mRNA vaccination vs. SARS-CoV-2 infection immune responses

A team of scientists from the United States has recently compared the immune response elicited by natural severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and coronavirus disease 2019 (COVID-19) vaccination. Their findings reveal that, unlike vaccination, natural SARS-CoV-2 infection is associated with a robust interferon response together with an induction of cytotoxic gene expression in peripheral blood lymphocytes. The study is currently available on the medRxiv* preprint server.

Preclinical study from NIH/Moderna: Correlates of SARS-CoV-2 immunity in non-human primates

Researchers in the United States have shown that the antibody response induced by the Moderna mRNA-1273 vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a correlate of immune protection against coronavirus disease 2019 (COVID-19) in non-human primates.

Drug-discovery collaboration finds potential new antimalarial drug candidates

Potential new antimalarial drug candidates are being developed through an extended drug-discovery collaboration between Australian medical research institute WEHI and Janssen Pharmaceutica NV. The collaboration was facilitated by Johnson & Johnson Innovation.

Researchers conduct a SARS-CoV-2 serosurvey of blood donors in New Zealand

New research has been released, which focuses on the transmission and prevalence of SARS-CoV-2 in New Zealand, through a blood donor serosurvey.

Metabolic testing of COVID-19 patients through skin imprints

There is, therefore, a great need to understand how the illness can be diagnosed using more convenient and inexpensive methods. A new study posted to the medRxiv preprint server reveals the potential role of skin imprints to test for biomarkers that indicate a diagnosis of COVID-19 in a non-invasive way.

SARS-CoV-2 vaccine with single-cycle adenovirus vector

Researchers in the United States have developed adenovirus vectors that may be more effective at generating immune responses against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) than those used in the vaccines that are currently being rolled out to help combat the coronavirus disease 2019 (COVID-19) pandemic.

Maintaining swimming pools in line with UK guidelines eliminates SARS-CoV-2 risk

Researchers in the UK have conducted a study showing that maintaining swimming pool water in accordance with UK guidelines is sufficient to eliminate the risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) being transmitted between bathers.

SARS-CoV-2 infection induces polyfunctional antibodies that can destroy infected cells

Drawing on epidemiological field studies and the FrenchCOVID hospital cohort coordinated by Inserm, teams from the Institut Pasteur, the CNRS and the Vaccine Research Institute (VRI, Inserm/University Paris-Est Créteil) studied the antibodies induced in individuals with asymptomatic or symptomatic SARS-CoV-2 infection.

New blood-based test detects lymph node metastasis in individuals with high-risk T1 colorectal cancer

Scientists at City of Hope, a world-renowned independent research and treatment center for cancer and diabetes, have developed a novel, noninvasive liquid biopsy test for detecting lymph node metastasis in individuals with high-risk T1 colorectal carcinoma.

Researchers explore cost-effective identification method for novel SARS-CoV-2 variants

In a new study, a rapid and cost-effective method of detecting known variants of concern has been developed utilizing capillary electrophoresis, allowing local facilities to screen for and track SARS-CoV-2 variants of concern and implement reactionary procedures.

Can a single BNT162b2 vaccine dose confer protective immunity against SARS-CoV-2 variants?

A team of researchers in Germany aimed to determine if the Pfizer-BioNTech vaccine mRNA vaccine (also known as the BNT162b2 vaccine) induces robust antibody responses against emergent SARS-CoV-2 variants, including the United Kingdom (or B1.1.7) variant; the South African (or B.1.351) variant; and the Brazilian (or P.1) variant.

Characterization of lab-produced neutralizing antibodies targeting SARS-CoV-2

A new study led by Hans-Martin Jäck of the Friedrich-Alexander University Erlangen-Nuremberg in Germany engineered clusters of neutralizing monoclonal antibodies using a transgenic mouse model. A unique characteristic for the antibodies was the different ways it bound to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the overall reduction in the viral spread for human ACE2.

Seroprevalence studies monitoring SARS-CoV-2 among vaccinees require more than spike assays

Researchers in the United States have shown that an antibody test measuring host reactivity to the nucleocapsid protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may better detect natural infection among vaccinated individuals than an assay that measures reactivity to the viral spike protein.

Can fingerprick blood tests help evaluate antibody response and longevity against SARS-CoV-2 post-vaccination?

To monitor antibody level duration of vaccine-induced immune responses, a team of researchers in the U.S. – at Diacarta, University of California and VA Healthcare System, and the Franciscan University of Steubenville – evaluated the feasibility of using a single drop of fingerstick blood collected with flocked swabs for quantitative antibody response evaluation after COVID-19 vaccination.

Just one mRNA vaccine dose sufficient for people with prior SARS-CoV-2 infection

A small study, previously posted to the medRiv preprint server in early March, was recently published in the journal Science Immunology. The now peer-reviewed research led by E. John Wherry of the University of Pennsylvania Perelman School of Medicine finds people previously exposed to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) produced a more robust immune response after receiving the first — but not the second mRNA vaccine.
