A new study by Laboratory Corp. of America Holdings (Labcorp) has found that nearly 9 in 10 COVID-19 patients continue to have antibodies to SARS-CoV-2 proteins 10 months after infection. Published in The Lancet-affiliated Eclinicalmedicine, the study provides real-world evidence of the persistence of SARS-CoV-2 antibodies in infected individuals, though the authors said more research is needed to determine if, and to what degree, protection against reinfection persists.
