Figure 1. SARS-CoV-2 antigen-specific IgG levels in poultry farm
personnel, COVID-19 patients, and pre-pandemic controls. (A )
anti-S1 IgG, (B ) anti-RBD IgG, (C ) anti-S2 IgG and
(D ) anti-N IgG OD ratios in sera from vaccine implementers
(n=39, pink circles closed) and poultry workers (n=14, pink circles
open), non-hospitalized COVID-19 patients (n=19, black circles open),
hospitalized COVID-19 patients (n=18, black circles closed), and
pre-pandemic control samples (n=38, turquoise circles). Dashed lines
indicate the threshold level at 0.1. Statistical analyses were performed
using the Kruskal-Wallis test. *P< 0.05,
****P<0.0001. Horizontal bar represents mean values.
(E ) Heatmap of IgG antibody response of sera from vaccine
implementers (VI1-VI39) and poultry workers (PW1-PW14), non-hospitalized
COVID-19 patients (C1-C19), hospitalized COVID-19 patients (C20-C37),
and pre-pandemic control samples (H1-H38). The color key indicates IgG
OD ratios, with blue shades indicating elevated ratios while white
shades indicating lower ratios. (F ) Frequency of vaccine
implementers and poultry workers with >0.1 IgG OD ratios
for S1, RBD, S2, and N.
Figure 2. IBV-specific IgG levels in poultry farm personnel,
COVID-19 patients, and pre-pandemic controls. (A ) anti-4/91
IgG, (B ) anti-IS/1494/06 IgG, (C ) anti-M41 IgG and
(D ) anti-D274 IgG OD ratios in sera from vaccine implementers
(n=39, pink circles closed) and poultry workers (n=14, pink circles
open), non-hospitalized COVID-19 patients (n=19, black circles open),
hospitalized COVID-19 patients (n=18, black circles closed), and
pre-pandemic control samples (n=38, turquoise circles). Dashed lines
indicate the threshold level at 0.1. Statistical analyses were performed
using the Kruskal-Wallis test. *P< 0.05, ***P<0.001.
Horizontal bar represents mean values. (E ) Heatmap of IgG
antibody response of sera from vaccine implementers (VI1-VI39) and
poultry workers (PW1-PW14), non-hospitalized COVID-19 patients (C1-C19),
hospitalized COVID-19 patients (C20-C37), and pre-pandemic control
samples (H1-H38). The color key indicates IgG OD ratios, with blue
shades indicating elevated ratios while white shades indicating lower
ratios. (F ) Frequency of vaccine implementers and poultry
workers with >0.1 IgG OD ratios for 4/91, IS/1494/06, M41,
and D274.
Figure 3. SARS-CoV-2 peptide-specific IgG levels in poultry farm
personnel, COVID-19 patients and pre-pandemic controls. (A )
anti-ORF3a (aa 172-205) IgG, (B ) anti-N (aa 153-176) IgG,
(C ) anti-N (aa 221-244) IgG, (D ) anti-N (aa 358-381)
IgG, (E ) anti-N (aa 382-405) IgG, (F ) anti-S (aa
547-570) IgG, (G ) anti-S (aa 782-805) IgG, (H ) anti-S
(aa 807-830) IgG, (I ) anti-S (aa 1138-1161) IgG, (J )
anti-Rhinovirus A (aa 567-591) IgG, (K ) anti-HHV 4 (aa 398-422)
IgG, and (L ) anti-HIV-1 (aa 967-991) IgG OD levels in sera from
vaccine implementers (n=39, pink circles closed) and poultry workers
(n=14, pink circles open), non-hospitalized COVID-19 patients (n=19,
black circles open), hospitalized COVID-19 patients (n=18, black circles
closed), and pre-pandemic control samples (n=38, turquoise circles).
Dashed lines indicate the threshold level at 0.1. Statistical analyses
were performed using the Kruskal-Wallis test. *P< 0.05,
**P< 0.01, ***P< 0.001, ****P<0.0001.
Horizontal bar represents mean values. (M ) Heatmap of IgG
antibody response of sera from vaccine implementers (VI1-VI39) and
poultry workers (PW1-PW14), non-hospitalized COVID-19 patients (C1-C19),
hospitalized COVID-19 patients (C20-C37), and pre-pandemic control
samples (H1-H38). The color key indicates IgG OD ratios, with blue
shades indicating elevated ratios while white shades indicating lower
ratios.
Figure 4. Differences in IgG OD ratios based on the work
experience of vaccine implementers and poultry workers. Statistical
analyses were performed using the Kruskal-Wallis test (ANOVA if
parametric distribution). *P< 0.05, **P<0.01.
Individuals were categorized into three groups as follows: (A )
vaccine implementers (2-20 months, n=11; 21-100 months, n=19;
>100 months, n=9) and (B ) poultry workers (2-20
months, n=5; 21-100 months, n=5; >100 months, n=4).

Rhinovirus-, and Human Herpesvirus 4-specific IgG levels in (A )
poultry farm personnel, (B ) COVID-19 patients, and (C )

correlation. *P< 0.05, **P<0.01, ***P<
0.001, ****P<0.0001.
