  1. The PPSV23 vaccinated and unvaccinated groups were defined by the questionnaire responses only, irrespective of the vaccination records in electronic medical record. There were significant positive relationships between PPSV23 vaccination and the following factors: perceived effectiveness of PPSV23, physician’s recommendations, and awareness of PPSV23 and public subsidies, while an inverse relationship was observed between PPSV23 vaccination and personal medical history of pneumonia (p < 0.05)
