8.5 percent of COVID-19 patients do not seroconvert

A new study published on the preprint server medRxiv in June 2020 reports on the use of inexpensive and accurate ELISA and rapid diagnostic tests (RDT) to identify the demographic and clinical factors that affect the antibody response in COVID-19 patients.

Scientists find COVID-19 antibodies fade quickly

Now, a new study shows that the levels of antibodies found in recovered coronavirus disease (COVID-19) patients declined sharply in just two to three months after infection for both symptomatic and asymptomatic patients.

Single-dose Israeli vaccine candidate protective against SARS-CoV-2

Now, a new Israeli study published on the preprint server bioRxiv in June 2020 reports a new recombinant vaccine expressing the S or spike protein of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to be highly protective with a single dose in an animal model. This could be a gamechanger in the fight to contain the outbreak.

Prior infection provides protection against SARS-CoV-2 virus in hamsters

In an animal model for COVID-19 that shares important features of human disease, scientists at the University of Wisconsin–Madison, the University of Tokyo and the Icahn School of Medicine at Mount Sinai show that prior infection with the SARS-CoV-2 virus provides protection against reinfection, and treatment with convalescent serum limits virus replication in their lungs.

New insights on antibody testing and RNA testing for SARS-CoV-2

Two types of tests are used to track SARS-CoV-2. Reverse transcriptase PCR (rt-PCR) tests for current infection. Antibody tests reveal that an infection has taken place, even long after the fact.

Three vaccine candidates race to combat SARS-CoV-2

As the coronavirus disease (COVID-19) ravages across the globe, scientists are racing to develop an effective vaccine to combat the viral infection. Caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the disease has infected nearly 9 million people.

Maintaining social distancing and using face masks could help avoid a second COVID-19 wave

Individual behavior has a significant effect on preventing a large second wave of COVID-19 infections. In fact, maintaining social distancing and other interventions such as the use of face masks and hand hygiene could remove the need for future lockdowns, according to a modeling study performed by the Barcelona Institute for Global Health, an institution supported by the "la Caixa" Foundation.

The role of brain cells in spreading HIV

Dr. Lena Al-Harthi speaks to News-Medical about her research into HIV treatment and the role of brain cells in spreading the HIV virus.

Synthetic peptide could be an effective COVID-19 treatment and SARS-CoV-2 vaccine

Ligandal, one of the world’s leading genetic medicine companies, has modeled a synthetic peptide that could be an effective COVID-19 treatment and SARS-CoV-2 vaccine.

A highly sensitive and specific antibody test for COVID-19

A new proof-of-concept study by UK researchers, currently available on the medRxiv* preprint server, describes the development of an enzyme-linked immunosorbent assay that can be used when lower levels of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) specific-antibodies are present in serum and saliva samples.

Balanced B and T cell response required to control SARS-CoV-2

A new study by researchers in the Netherlands and published on the preprint server bioRxiv in June 2020 describes the differences in T and B cell responses seen in patients with severe COVID-19.

New adjuvant helps induce long-lasting immunity against HIV

Researchers at the Yerkes National Primate Research Center and the Emory Vaccine Center (EVC) are first to show a new adjuvant, 3M-052, helps induce long-lasting immunity against HIV.

MMR vaccine could offer protection against COVID-19

Administering the MMR (measles, mumps, rubella) vaccine could serve as a preventive measure to dampen septic inflammation associated with COVID-19 infection, say a team of experts in this week's mBio, a journal of the American Society for Microbiology.

Characterizing "re-positives" in recovered COVID-19 patients

The novel coronavirus pandemic has been spreading silently or explosively in almost every country of the world, causing almost half a million deaths and nearly 8.5 million reported cases in just six months. While much is known about the virus and the illness by now, far more remains unclear. One such is the prevalence and persistence of antiviral immunity following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.

Researchers find prothrombotic antibodies in patients with COVID-19

Even as the COVID-19 pandemic continues to spread across the world, researchers are still trying to understand the many ways in which it can manifest and its pathogenesis. A new report published on the preprint server medRxiv* in June 2020 shows that one possible mechanism of disease in COVID-19 is the production of antiphospholipid antibodies.

Throat gargling may be beneficial during the COVID-19 pandemic

Researchers from Chang Gung University College of Medicine, Taiwan, have suggested that throat gargling may have beneficial effects during the coronavirus disease 2019 (COVID-19) pandemic.

Study: Vitamin D can reduce side effects associated with chemotherapy

As many cancer patients will confirm, the chemotherapy prescribed to kill the disease is often more debilitating than the cancer itself, with a range of horrendous side effects.

Japanese health supplement could help tackle Covid-19 in people with comorbid conditions

A unique Beta 1,3-1,6 Glucan based Japanese health supplement, produced by black yeast, Aureobasidium Pullulans, could strategically help tackle Covid-19 in people with comorbid conditions like diabetes, kidney and heart diseases, as published in Frontiers in Immunology Journal recommending clinical studies, for validation.

UConn researchers tackle a vexing problem in the development of vaccines

Researchers at UConn's Center of Excellence in Vaccine Research have made a breakthrough in vaccine development for a common and difficult to treat pneumonia-causing pathogen. Their research was recently published in the Nature Partner Journal - Vaccines.

A new system for detecting antibodies within minutes

To defend the body, the immune system makes proteins known as antibodies that latch onto the perceived threat, be it HIV, the new coronavirus or, as is the case in autoimmune disease, part of the body itself.
