13vPnC serotypes: 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F. Analysis was based on pneumococcal serogroup designation. LAZ, length-for-age Z score; InPACT, Infant Pneumococcal Acquisition/Colonization in Tamil Nadu; WAZ, weight-for-age Z score; WLZ, weight-for-length Z score; , Streptococcus pneumoniae.
