New data on impact of spike mutations and B117 UK variant on neutralization by mAbs and sera

A recent paper by British and Dutch scientists, currently available on the bioRxiv* preprint server, shows that the neutralizing activity of monoclonal antibodies can be dramatically reduced by mutations of the SARS-CoV-2 spike glycoprotein – unlike polyclonal antibodies generated after natural infection that remain active regardless of any introduced amino acid changes.

Pfizer-BioNTech vaccine shows reduced neutralization potential against SARS-CoV-2 B.1.1.7 spike variant

Researchers in the UK have conducted a study assessing the efficacy of the Pfizer-BioNTech COVID-19 vaccine BNT162b2 against the new variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Dynamic, customized treatment approaches for gastroesophageal cancers may improve survival rates

A phase 2 clinical trial providing personalized treatments based on the genetic profile of metastatic tumors in gastroesophageal cancers has found that using customized treatment approaches, and adapting them over time as tumors become resistant, led to higher rates of survival compared to historical controls.

Blood group associated with cardiovascular events in COVID-19 patients

An illuminating new study by scientists at Harvard Medical School, USA, describes the correlation of such conditions with the ABO blood group. The team's findings may help assess the risk of COVID-19 patients for such complications, promoting early diagnosis and underscoring potential needs for preventive and therapeutic care where possible.

South African SARS-CoV-2 variant escapes antibody neutralization

Researchers in South Africa have conducted a study showing that the novel 501Y.V2 variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that has emerged in the country is able to escape the neutralizing antibodies that are elicited by previously circulating strains of the virus.

Patients fend for themselves to access highly touted covid antibody treatments

By the time he tested positive for covid-19 on Jan. 12, Gary Herritz was feeling pretty sick. He suspects he was infected a week earlier, during a medical appointment in which he saw health workers who were wearing masks beneath their noses or who had removed them entirely.

Immune systems of COVID-19 patients may rely on antibodies from earlier coronaviruses

The results of a study led by Northern Arizona University and the Translational Genomics Research Institute (TGen), an affiliate of City of Hope, suggest the immune systems of people infected with COVID-19 may rely on antibodies created during infections from earlier coronaviruses to help fight the disease.
