Abstract
Seven-valent pneumococcal conjugate vaccine (PCV7) was introduced into the Norwegian childhood vaccination program in July 2006 in a 2+1 dose (three-dose) schedule. Vaccine coverage quickly reached high levels and the incidence rate of invasive pneumococcal disease in children under 2 years of age declined rapidly. The vaccine program's effectiveness was estimated to be 74%.
