Résumé
We measured Anti-Spike (S), Nucleoprotein (N) and neutralizing antibodies (NAbs) in sera from 308 RT-qPCR + healthcare workers with mild disease, collected at two time-points up to 6 months after symptom onset. At Month 1 (M1), anti-S and N antibody levels were higher in males > 50 years or with a body mass index (BMI) > 25. At M3-6, anti-S and anti-N antibodies were detected in 99% and 59% of individuals, respectively. Anti-S antibodies and NAbs declined faster in males than in females, independently of age and BMI, suggesting an association of sex with evolution of the humoral response.
