Primary Outcome Measures:
  • Serological studies of pneumococcal proteins and their development over time following otitis media infections [ Time Frame: 3 months per individual ]
    The serological studies will study the natural immune response to protective pneumococcal vaccine antigens.


Biospecimen Retention:   Samples Without DNA
Plasma

Estimated Enrollment: 100
Study Start Date: October 2010
Estimated Study Completion Date: July 2014
Estimated Primary Completion Date: March 2014 (Final data collection date for primary outcome measure)
Groups/Cohorts
Control group - culture negative
50 children with pneumococcal culture-negative Acute Otitis Media
study group- culture positive
50 children with pneumococcal culture-positive Acute Otitis Media
