Since SARS-CoV-2 was discovered in Illinois over a year ago, scientists at Northwestern University’s Feinberg School of Medicine have been tracking the evolution of the disease in the Chicago area. Ramón Lorenzo Redondo, PhD, research assistant professor of Medicine in the Division of Infectious Diseases, is part of the team leading this work. He talks about the team’s research, the new COVID-19 variants and how the vaccines on the market today stand up to them.
