Figure 4. Local SARS-CoV-2 antibodies in upper respiratory samples of vaccinated individuals.

Figure 4.

A) IgG levels by ELISA in the upper respiratory samples collected from patients positive after full vaccination (N=114) and association with the days after receiving the second dose of the COVID-19 vaccine. B) SARS-CoV-2 IgG correlation to cycle thresholds of the N gene using the PerkinElmer SARS-CoV-2 assay. C) SARS-CoV-2 IgG correlation to days to the first appearance of cytopathic effect (CPE) on Vero-TMPRSS2 cells. Dashed line demarcates the limit of borderline and negative ELISA results as specified per assay’s package insert.
