Associations between pneumococcal isolates with vaccine serotypes and BAPS clusters. The vaccine serotypes are those present in the seven valent pneumococcal vaccines (4, 6B, 9V, 14, 18C, 19F, and 23F), and all records present in the MLST database at the time of BAPS analysis were used to estimate ORs. Reestimation using records entered into the database since the initial analysis did not substantially alter the results (22).
