COVID-19 Antibodies Last at Least 5 Months, Study Suggests

COVID-19 patients may produce antibodies for at least five months after initial infection, according to a study published in the journal Immunity. Researchers at the University of Arizona Health Sciences in Tucson analyzed antibody production from 5,882 blood samples collected in Arizona's Pima County as part of a larger effort to create and validate a COVID-19 antibody test.
