Repeat COVID-19 cases could offer clues about people’s immunity to the novel coronavirus and how to vaccinate against it

At least 285 individuals in Mexico appear to have contracted the novel coronavirus twice, according to a preprint posted October 18 on medRxiv. The study, which has not yet been peer reviewed, is the largest to date to assess the possibility of SARS-CoV-2 reinfection. It fuels an ongoing discussion among researchers about how long immunity to the virus lasts after an initial infection and how that length of immunity may affect the way vaccines against the virus are administered in the future.
... study coauthor Carlos Hernandez-Suarez, a researcher at Universidad de Colima in San Sebastian, Mexico, tells The Scientist, adding that no conclusions can be made from the current data about the strength of survivors’ immunity or the protection offered by future vaccines. In his team’s analysis of hospital records of 100,432 individuals infected with SARS-CoV-2 between March and July 2020, only 285 (0.26 percent) presented signs that they’d contracted the virus twice.
