Table 1 Pneumococcal upper respiratory tract isolates analysed in this study. Incidences from 2 years prior to start of vaccination are compared to 3 years after PCV introduction

From: Reduction of Streptococcus pneumoniae in upper respiratory tract cultures and a decreased incidence of related acute otitis media following introduction of childhood pneumococcal conjugate vaccines in a Swedish county
