Prevnar (7 valent pneumococcal conjugate vaccine [7vPnC]) has been shown to be effective against ear infections in children. Prevnar 13 is a new vaccine that is similar to Prevnar. It is expected that the effectiveness of Prevnar 13 against ear infections in children will be similar to that observed following Prevnar. Pfizer has committed to conduct a postmarketing study of the impact of Prevnar 13 in reducing ear infections among children.
Infants who have completed the Prevnar 13 infant vaccination series who provide consent and fit the study inclusion criteria to participate in the study will be recruited.

| FG000 | Prevnar 13 | Participants who were 6 to 12 months of age and had completed immunization schedule of the Prevnar 13 infant series or participants who were up to 30 months of age and met the criteria for recurrent acute otitis media (AOM) were enrolled. Recurrent AOM was defined as greater than or equal to (>=)3 distinct episodes in a 6-month period or >=4 distinct episodes in a 12-month period. Participants who were diagnosed with AOM, underwent both nasopharyngeal/oropharyngeal (NP/OP) swab and diagnostic tympanocentesis (or collection of MEF via swab if tympanocentesis could not be performed). |
