Evaluation of Knowledge, Attitude, and Practice of Pneumococcal Vaccine among Geriatric Population by a Questionnaire-based Study

Introduction: This study delves into the impact of Streptococcus pneumoniae , a Gram-positive bacterium causing invasive and noninvasive diseases, predominantly affecting the elderly and young. Pneumococcal diseases significantly contribute to global morbidity and mortality, necessitating effective preventive measures. The demonstrated effectiveness of pneumococcal vaccines, namely PPSV23 and PCV13, in alleviating the risks linked to invasive pneumococcal disease has been clearly affirmed by numerous international studies. Despite this evidence, global vaccination rates remain suboptimal. Materials and Methods: This cross-sectional study aimed to bridge knowledge gaps and assess the understanding of vaccination practices among the elderly. Data collection was done with a standardized questionnaire. The sample size was 106, participants aged 65 years and above attending a tertiary care center and excluding individuals who were already vaccinated. Written informed consent was obtained, ensuring participant confidentiality. Statistical analysis was performed using SPSS 20 software. Results: The awareness rate of pneumococcal vaccine was 24%. Male participants (67.9%) predominated over female participants (32.1%). Most of the participants fall within the age group of 65–69 years. The study also shed light on the gap that exists in the understanding of specific risk factors. Conclusion: The awareness of pneumococcal vaccine is significantly low in the study population. Public health measures such as the promotion of vaccines in a government institution are crucial to protect vulnerable individuals from succumbing to community-acquired pneumonia.
