Dehgani-Mobaraki P, Zaidi AK, Yadav N, et al. - For future health policy implementation, it is crucial to understand antibody responses post SARS-CoV-2 natural infection.

• Longitudinal analysis of IgG antibody titers in recovered COVID-19 patients after mild and moderately-severe infection revealed persistence of anti-spike-receptor binding domain IgG in 96.8% individuals at 14 months.

• Significantly higher antibody titers were recorded in patients describing loss of smell and taste during the clinical course of the disease.

• False-negative rates were higher in correlation with using nucleocapsid protein-based antibody assays and their avoidance is emphasized in routine analysis.
