A Study to Learn About How 20-Valent Pneumococcal Conjugate Vaccine Works in a Real-world Setting

Brief Summary
The purpose of this study is to learn about how well the 20-valent pneumococcal conjugate vaccine (20vPnC) works against radiologically-confirmed community-acquired pneumonia (RAD+CAP) due to the 7 new serotypes (types of a bacteria called Streptococcus pneumoniae that cause pneumonia) included in 20vPnC vaccine. This study is seeking participants who:
- are male or female ≥65 years of age.
- are hospitalized with physician suspicion of community acquired pneumonia (CAP).
- have pneumonia confirmed with imaging like a chest x-ray Participants will be asked to provide demographic and medical history information, and to provide a urine sample that will be used to test for pneumonia caused by specific strains of a bacteria called Streptococcus pneumoniae. We will compare the proportion of participants who have pneumonia caused by specific strains of the bacteria Streptococcus pneumoniae and were previously vaccinated with 20vPnC with the proportion of participants who have pneumonia caused by something other than vaccine type Streptococcus pneumoniae and have been vaccinated with 20vPnC. Participants will actively take part in the study for about 1-2 days. Information on participant's illness and hospitalization details will be collected through day 30 of their hospitalization through medical chart review.

Outcome Measures
Primary Outcomes (1)
Effectiveness of 20vPnC against all (invasive + non-invasive) RAD+CAP due to the 7 additional serotypes in 20vPnC beyond 13vPnC plus 15C
Vaccine effectiveness as calculated as 1 minus the odds ratio for 20vPnC vaccination among cases vs. controls multiplied by 100 adjusted for potentially confounding variables
55 months
Secondary Outcomes (18)
Effectiveness of 20vPnC against non-invasive RAD+CAP due to the 7 additional serotypes in 20vPnC beyond 13vPnC plus 15C
55 months
Effectiveness of 20vPnC against all RAD+CAP due to any 20vPnC serotype plus 6C and 15C
55 months
Effectiveness of 20vPnC against non-invasive RAD+CAP due to any 20vPnC serotype plus 6C and 15C
55 months
Proportion of participants with RAD+CAP due to the 7 additional serotypes in 20vPnC beyond 13vPnC plus 15C, individually and aggregately
55 months

Study Arms (2)
Case
Cases will be defined as participants hospitalized for RAD+CAP in whom the 7 additional serotypes in 20vPnC beyond 13vPnC plus 15C are identified.
Control
All other participants who meet study inclusion criteria but for whom 20vPnC serotypes are not identified from any source and all other RAD+CAP of non-pneumococcal etiologies will serve as test-negative controls.
Interventions
Testing by BinaxNOW® S. pneumoniae and serotype-specific urine antigen detection (UAD) assays (UAD-1 and UAD-2).
Eligibility Criteria
Males and females ages 65 and older hospitalized for suspected community acquired pneumonia.
You may qualify if:
- Male or female participants ≥65 years of age.
- Hospitalized participant with physician clinical suspicion of CAP with the presence of ≥2 of the following 10 clinical signs or symptoms:
- fever (oral temperature \>38.0°C/100.4°F or tympanic temperature \>38.5°C/101.2°F),
- hypothermia (\<35.5°C/95.9°F measured by a healthcare provider)
- chills or rigors,
- pleuritic chest pain,
- new or worsening cough,
- sputum production,
- dyspnea (shortness of breath),
- tachypnea (respiratory rate \>20/min),
- malaise, or
- abnormal auscultatory findings suggestive of pneumonia (rales or evidence of pulmonary consolidation including dullness on percussion, bronchial breath sounds, or egophony).
- Has a radiographic finding that is consistent with pneumonia (e.g., pleural effusion, increased pulmonary density due to infection, the presence of alveolar infiltrates \[multi-lobar, lobar, or segmental\] containing air bronchograms).
- Capable of giving signed informed consent
You may not qualify if:
- Any participant who develops signs and symptoms of pneumonia after being hospitalized for ≥48 hours (either at the study site, another transferring hospital, or a combination of these).
- Received any pneumococcal vaccine ≤30 days prior to enrollment.
- Unable to provide urine specimen (e.g. anuric).
- Previous enrollment in the study within the past 30 days.
