A significant decrease of invasive Haemophilus influenzae diseases (IHD) occurred in nations that implemented routine Hib vaccination in their national immunization program (NIP). Aim: The goal of this study was to describe the frequency and characteristics of pediatric patients with IBD before and after routine Hib vaccination was implemented into the Croatian national immunization program (NIP). Subjects and methods: A retrospective analysis of patient records from administrative databases for patients aged 0 to 18 with etiologically proven IBD at University Hospital for Infectious Diseases “Dr. Fran Mihaljević”. Results: A total of 1.112 pediatric patients were analyzed. The patients were divided into three periods: one prevaccinal (reference) and two postvaccinal periods.
