Background/Significance: Streptococcus pneumoniae is responsible for 20-60% of U.S. bacterial pneumonia cases and has a mortality rate of 10-30%. Invasive pneumococcal disease (IPD) occurs when streptococcus pneumoniae invades otherwise sterile sites. Adherence to immunization guidelines is 60-70% effective at preventing IPD. Co-administration of pneumococcal and influenza vaccines has shown promise at increasing uptake of the pneumococcal vaccine and enhancing immunological response. Population/Setting: A state-run Department of Corrections (DOC) clinic system serving just over 30,000 individuals was the site for this project. Incarcerated individuals present an increased risk of contracting pneumococcal disease due to close living quarters. Other risk factors such as airway disease, immunocompromise, and smoking also compound the disease burden in this vulnerable population. Intervention: To increase pneumococcal vaccine uptake, co-administration of influenza and pneumococcal vaccines was offered during influenza clinics. A video update on the pneumococcal immunization guidelines was shared with staff. Clinic participants were educated with updated infographics in English and Spanish about their eligibility for vaccination and the risk of harm from IPD. Participation was voluntary. Results: The percentage of DOC participants vaccinated against pneumococcal disease increased from 43% (n=500) to 45% (n=523) of those >=65 years of age and those ever offered the vaccine increased from 48% (n=558) to 54% (n=651) during the study period. Comparing pre-and-post survey data, improvements were observed in the percentage of DOC staff stating they feel confident recommending pneumococcal vaccines (8.8% increase) and stating they are knowledgeable about the 2021 updates to the ACIP guidelines (28% increase).
