Introduction: Little is known about the completeness and timely administration of recommended standard immunizations in Germany. The goal of this study was to determine compliance with official standard immunization recommendations in adolescents attending secondary schools in the city of Erlangen, Germany. Methods: Adolescents who were attending 5th grade (at approximately 11years of age), 8th grade (14years), or 10th and 11th grade (16-17years) classes at any of the 13 of 14 schools that had agreed to participate were eligible to be enrolled. Results: While coverage for the primary series of diphtheria, tetanus and poliomyelitis immunizations was satisfactory (98%), coverage for measles-mumps-rubella immunizations (dose 1: 89-96%; dose 2: 60-76%) and hepatitis B (doses 1-3: 61%) was suboptimal. Of note, 39% of students had not received any immunization against pertussis. Completion of immunization series generally was significantly delayed. Furthermore, rates for recommended booster doses in adolescence were disappointingly low with 21% for tetanus component vaccines and

Two infants with life-threatening pertussis are presented in whom the diagnosis was delayed. A review of pertinent literature suggests that the diagnosis of pertussis in infants is frequently missed and therefore the morbidity and mortality from this disease is underestimated.
