High Seroprevalence but Short‐lived Immune Response to SARS‐CoV‐2 Infection in Paris

Category: Article Summary

Topic: Vaccines and Immunity

Keywords (Tags): immunity

Serological testing among 1847 active workers in France showed declining antibody responses to SARS‐CoV‐2 4-8 weeks after the first sampling. Overall, 11% of workers were positive for IgG against SARS-CoV-2-specific proteins and 9.5% had evidence of viral neutralization. Among these, 21% were asymptomatic. In sera obtained 4–8 weeks after the first sampling, anti‐N and anti‐S IgG titers and neutralization activity declined by 31%, 17% and 53%, respectively.
