Spearman’s rank correlation between anti-spike and anti-PEG antibodies in mouse plasma after 3 doses of Comirnaty. We conducted a Spearman’s rank correlation analysis to examine the relationship between the absorbance at OD405nm of anti-spike antibodies and the concentration of anti-PEG IgG + IgM antibodies. (A) The data were analyzed on day 28 after administering the 1st vaccine dose. (B) Data analysis was conducted on day 28 after the 2nd vaccine dose. (C) The data were analyzed on day 28 after the 3rd vaccine dose. Spearman’s rank correlation coefficient (ρ) was calculated, and statistical significance was determined. A P value of less than 0.05 was considered statistically significant.
