Model building approach was an automated forward-selection procedure using Likelihood ratios and a 10%-significance level as entry criterion. Only variables that fulfilled the entry criterion are displayed
a: all vaccination data refers to first dose
b: only children susceptible at the age of 11 months
c: only collected regarding recommendation of varicella vaccination
d: university entrance diploma at end of grammar school (‘Abitur’)
e: significant at 0.1% level
f: significant at 1% level
g: significant at 5% level
