[Pre-print, not peer-reviewed] A substantial proportion of individuals who lacked serological evidence of SARS-CoV-2 exposure showed antibody reactivity against SARS-CoV-2 antigens, possibly due to cross-reactivity of antibodies against other coronaviruses. Among 276 adults tested for SARS-CoV-2 antibodies during the second wave of the COVID-19 pandemic in Vancouver, Canada (May 17-June 19, 2020), 3 participants tested…
