[Pre-print, not peer reviewed] In a cohort of workers outside Paris, both the concentration (titer) and quality of antibodies against SARS-CoV-2 declined 4-8 weeks after sampling. Among a cohort of 1,847 active workers in the Paris conurbation in France, 11% were positive for IgG against SARS-CoV-2-specific protein and 9.5% had evidence of viral neutralization. After 4-8 weeks since the first sampling, anti-N and anti-S IgG titers and neutralization activity declined by 31%, 17%, and 53%, respectively.
