Princeton researchers report that the impact of natural and vaccine-induced immunity will be key factors in shaping the long-term trajectory of the global coronavirus pandemic, known as COVID-19, according to a study published Sept. 21 in the journal Science. In particular, a vaccine capable of eliciting a strong immune response could substantially reduce the future burden of infection. The study was led by co-first authors Chadi Saad-Roy, a Ph.D. candidate in Princeton’s Lewis-Sigler Institute for Integrative Genomics, and Caroline Wagner, who worked on the study as a postdoctoral research associate in PEI. Co-senior authors are PEI associated faculty members Bryan Grenfell, the Kathryn Briger and Sarah Fenton Professor of Ecology and Evolutionary Biology and Public Affairs, and C. Jessica Metcalf, associate professor of ecology and evolutionary biology and public affairs. https://www.princeton.edu/news/2020/09/21/long-term-covid-19-containment-will-be-shaped-strength-and-duration-natural-vaccine
