- Vaccine effectiveness (VE) [ Time Frame: 4 years ]VE calculated as 1 minus the OR* comparing the odds of having received PCV13 for cases and controls, multiplied by 100, overall and restricted to immunocompetent subjects only.
- Proportion of CAP events for each pneumococcal serotype, PCV-13, and 20-valent pneumococcal conjugate vaccine (PCV20) serotypes among all CAP subjects with UAD1/2 testing (overall) and among all CAP subjects with a pneumococcus identified [ Time Frame: 4 years ]Distribution of S. pneumoniae serotypes using blood, high-quality respiratory cultures, and a serotype-specific urinary antigen detection (UAD) assay among adults 60 years of age and older with CAP.
- Proportion of persons with respiratory pneumococcal carriage among adults 60 years of age and older presenting with CAP [ Time Frame: 4 years ]Proportion of CAP events where the pneumococcus was identified from saliva by the conventional culture or the sensitive molecular method of PCR divided by all CAP events where the subject had a valid saliva specimen test result.
- Proportion of participants with CAP and SP-CAP with underlying medical conditions [ Time Frame: 4 years ]Proportion of CAP subjects with underlying at-risk and high-risk medical conditions, overall and restricted to those with pneumococcus isolated from blood, high-quality respiratory cultures, and a serotype specific urinary antigen detection (UAD) assay
- Frequency of antibiotic resistance among Streptococcus pneumoniae isolates by type [ Time Frame: 4 years ]Proportion of S. pneumoniae isolates with antibiotic resistance identified by standard of care testing, overall and by resistance type
