The child immunisation programme--effective but insufficient. Experiences from the Astrid Lindgren pediatric hospital, 2008–2013

The national Swedish immunisation programme includes vaccine against diphtheria, tetanus, polio, pertussis, Haemophilus influenzae type B, Pneumococcus as well as measles, mumps and rubella. Data were collected on hospital admissions for children 0- 17 years of age of vaccine-preventable diseases during 2008-2013 at Astrid Lindgren Children's Hospital, Stockholm. Patients were identified by discharge diagnosis codes as well as from the clinical microbiology laboratory. There were rare cases of measles and mumps, and only a few cases of invasive bacterial diseases. The dominating pathogens were influenza A and B, rotavirus and varicella zoster virus. Our national programme is effective, but vaccine preventable infections still cause significant morbidity in young children. An extended vaccine programme might significantly reduce the need of hospitalisations.
