Some participants chose not to answer certain questions, resulting in a different number included in indicated analyses: race (n = 393), ethnicity (n = 395); and insurance coverage (n = 363). Vaccine records could not be located for 27 participants (n = 370).
^
Incomplete vaccination was defined as incomplete series for age. Six of the 11 colonized subjects had received 3 PCV doses, while 5 subjects received < 3 doses of PCV.
