Correlation coefficients between results related to immune response at 5 dpi and pathological changes in chickens vaccinated with AvCoV-CS and the challenged group.

	IgA	IgG	CD8β	Granzyme	Perforin
Viral load 5 dpi (T)	−0.499 *	−0.366	−0.323	−0.553 *	−0.147
Viral load 11 dpi (T)	−0.413 *	−0.487 *	−0.245	−0.551 *	-
Viral load 5 dpi (K)	-	−0.533 *	-	-	−0.508
Viral load 11 dpi (K)	-	−0.181	-	−0.517 *	-

dpi: days post infection; T: tracheal; K: kidney; * (asterisk) represents a significant correlation by Spearman’s correlation test with a 95% confidence interval.
