Trial of peptide-centered SARS-CoV-2 T-cell activator in B-cell deficient individuals

A recent phase 1/2 study under review at the Nature Portfolio journal and posted to the Research Square* preprint server demonstrated that a peptide-centered severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) T-cell activator, CoVac-1, was efficient in B-cell deficient people.

People with food allergies less likely to become infected with SARS-CoV-2, study finds

A National Institutes of Health-funded study has found that people with food allergies are less likely to become infected with SARS-CoV-2, the virus that causes COVID-19, than people without them. In addition, while previous research identified obesity as a risk factor for severe COVID-19, the new study has identified obesity and high body mass index (BMI) as associated with increased risk for SARS-CoV-2 infection.
