Testing for coronavirus Covid-19 in a lab. Covid medical screening

CDC publication acknowledges Aegis Sciences and Walgreens for their work

The Centers for Disease Control publishes two Morbidity and Mortality Weekly Reports utilizing spike-protein target failure/performance, SGTF/rSGTP, as a proxy to track emerging SARS-CoV-2 variants and vaccine effectiveness against Omicron sublineages related to BA.5 and XBB/XBB.1.5. Acknowledging Aegis Sciences and Walgreens for their work published previously in PLOS1, SGTF/rSTGP monitoring proves to be a critical public health tool for real-time SARS-CoV-2 surveillance.
