Table 2 Serotype distribution of Streptococcus pneumoniae carriage isolates (N = 168) among 438 children in daycare centers in Arkhangelsk, Russia, 2006. Proportion of isolates covered by three different pneumococcal vaccines PCV-10, −13 and PPV-23. Penicillin non-susceptible and macrolide non-susceptible strains, as well as strains with combined non-susceptibility to penicillin and macrolides are specified
