Enhanced neutralizing antibody and T-cell responses by DNA-based vaccine encoding SARS-CoV-2 spike protein

Researchers from VaxiGen have been investigating the potential for a DNA vaccine boost to VP vaccines against coronavirus disease 2019.

Drinking alcohol and not exercising are modifiable risk factors for SARS-CoV-2

New research from the United Kingdom suggests several factors that increased the risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection involved higher alcohol use, Asian/Asian British ethnicity, and obesity. In addition, moderate but not vigorous exercise of more than 10 hours a week was associated with lower susceptibility to infection.

Increase in SARS-CoV-2 seroprevalence in Irish HCWs during third wave of pandemic

Healthcare workers and people they live with are at an increased risk of contracting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Hospital healthcare workers (HCWs) worldwide have been found to have a higher number of SARS-CoV-2 infections and higher antibody seroprevalence compared to the general population.

Scientists develop a high-throughput, cell-free screening platform for anti-SARS-CoV-2 antibody discovery

Scientists from Northwestern University, USA, have recently developed a high-throughput, automated screening platform to rapidly identify anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies. The study is currently available on the bioRxiv* preprint server.

Study reveals cellular mechanism behind older adults' susceptibility to COVID-19

Among the populations most significantly affected by COVID-19 are the elderly and patients with preexisting medical conditions including diabetes, hypertension, obesity, metabolic syndrome, cardiovascular disease and chronic lung diseases like COPD and asthma.

Discovery of potent neutralizing antibodies against SARS-CoV-2 variants

In a recent study, the researchers identify and characterize mAbs that are effective against the wild-type SARS-CoV-2 strain and B.1.351 variant.

Study compares efficacy of BNT162b2 and CoronaVac as the booster dose for COVID-19 vaccination

A recent study reports the immunogenicity and safety of BNT162b2 and CoronaVac as the third dose in CoronaVac-immunized adults.

Researchers explain why decaying SARS-CoV-2 antibodies in blood are not a problem after vaccination

A new study published in the preprint bioRxiv* server suggests vaccination helps to inflate the number of somatic hypermutations acquired by B cells. The increase in somatic hypermutations allows for an accumulation of highly matured bone marrow plasma cells.

Rapid antibody response induced by mRNA COVID vaccines in mice

A new study posted in the bioRxiv* preprint server used mouse models to investigate how mRNA vaccines elicit a rapid antibody response. Their findings show two different mRNA vaccines successfully boost antibody levels — IL-5, IL-6, and MCP-1 —5 days after administration.

New data points to major SARS-CoV-2 animal reservoir in deer in Iowa

A new study tests the hypothesis that white-tailed deer are susceptible to SARS-CoV-2 infection.

Convalescent plasma post-vaccination increases binding and neutralizing antibodies against SARS-CoV-2 variants

A recent study assesses the boost in antibodies against SARS-CoV-2)variants post-vaccination in plasma samples from previously infected COVID-19 patients.

New type of COVID vaccine potentially easier to produce and does not need refrigeration

Currently available COVID vaccines require cold storage and sophisticated manufacturing capacity, which makes it difficult to produce and distribute them widely, especially in less developed countries.

Study opens a window for new therapeutic approaches to ovarian cancer

A Ludwig Cancer Research study has uncovered a cellular interaction that is essential to the ability of the immune system's cytotoxic T lymphocytes to destroy ovarian tumors and shown that its engagement could help determine the efficacy of checkpoint blockade immunotherapy in a variety of cancers.
