Incidence of all adverse events occurring in the Zagreb and Essen groups during the trial

Type of reaction	Zagreb group (n = 549)	Essen group (n = 275)	P value
AEs, any, n (%)	102 (18.6)	51 (18.6)	0.99#
AEs possibly or probably related to the vaccine, n (%)	6 (1.1)	9 (3.3)	0.03#
AEs leading to discontinuation, n (%)	1 (0.2)	1 (0.4)	1.00*
SAEs, n (%)	0	1 (0.4)	0.33*

AE = adverse event; SAE = Serious AE.

# Chi-Square test.

*P value was determined by Fisher exact probability method.
