Researchers examine the evolutionary race between SARS-CoV-2 and human defenses

Researchers have analyzed this evolution of the virus based on evolutionary ecology theory. Using the virus genomes available in the Global Initiative on Sharing Avian Influenza Data (GISAID) database, the researchers focused their inquiry on mutations in the receptor-binding domain (RBD) on the spike protein of SARS-CoV-2.

Single dose of Pfizer and Oxford vaccines shows 60% efficacy in elderly care home residents

A new study deals with the effect of two widely used vaccines in eliciting humoral immunity against the virus in this group. These are the Oxford/AstraZeneca viral-vectored vaccine (ChAdOx1 nCoV-19), and the Pfizer/BioNTech’s messenger RNA-based vaccine (BNT162b2). Both express the viral spike antigen, and both are currently being employed in the UK’s vaccination program.
