a
NA, not applicable (18C was not specifically tested for).
b
Remaining PCV-10 serotypes except the PCV-7 serotypes.
c
Serotype 7F/A is considered a PCV-10 and a PCV-13 serotype.
d
Remaining PCV-13 serotypes except the PCV-10 serotypes.
e
Two of these were mixed infections of serotypes 1 and 5.
f
Total number of isolates positive for S. pneumoniae from 53 patients (two were mixed infections). This value was used to calculate serotype coverage.
