New simulation model shows how likely the SARS-CoV-2 virus spreads in different school settings

A year ago, the whole world discussed: is it irresponsible to send children to school during a pandemic, or do measures exist that can prevent corona clusters so efficiently that schools can stay open (or reopen)?

Masking young children linked with fewer childcare program closures due to COVID-19

A new Yale study found that child care programs in the United States that practiced child masking early in the COVID-19 pandemic (May-June 2020) experienced a 13% reduction in program closure within the following year, and continued child masking throughout the one-year study period was associated with a 14% reduction in program closure.

Scientists identify immunogens that can elicit antibody responses against multiple SARS-CoV-2 variants

In a new study, researchers identified conserved sites in the SARS-CoV-2 spike protein using structural and sequence data, and then combined the results with existing deep mutational scanning data to design six antigens that can offer protection against significant immune escape mutations in the SARS-CoV-2 receptor-binding domain.
