One of the most significant questions about the novel coronavirus is whether people who are infected are immune from reinfection and, if so, for how long.
To determine the answer, University of Arizona Health Sciences researchers studied the production of antibodies from a sample of nearly 6,000 people and found immunity persists for at least several months after being infected with SARS-CoV-2, the virus that causes COVID-19.
The resulting paper, “Orthogonal SARS-CoV-2 Serological Assays Enable Surveillance of Low Prevalence Communities and Reveal Durable Humoral Immunity,” was published today in the journal Immunity. Dr. Bhattacharya and Janko Nikolich-Zugich, MD, PhD, professor and head of the Department of Immunobiology, led the research team.
