Purpose: The purpose of this study was to confirm the current status of pneumococcal vaccination in adults over 65 years old and to identify factors related to pneumococcal vaccination. Methods: The research design was a descriptive survey design using convenience sampling. Data collection was conducted at senior citizen centers and schools for elders. A self-report questionnaire was completed by 131 older adults. Data collection period was from March 1 to 31, 2017. Data were analyzed using numbers, percentages, means, standard deviation, x2 test, t-test, and logistic regression with the IBM SPSS Statistics 19.0 program. Results: Pneumococcal vaccination rate for older adults was 51.1%. Pneumococcal vaccination was associated with chronic disease (adjusted odds ratio [OR]=548.27, 95% CI: 26.67~999.99) and attitude toward pneumococcal vaccination (adjusted odds ratio [OR]=1.33 95% CI: 1.16~1.53). Conclusion: Pneumococcal vaccination rate for elders was about 50% and chronic disease positively affected the pneumococcal vaccination rate. To improve the pneumococcal vaccination rate for older adults, it is necessary to develop an intervention plan to define the role of nurses in vaccination for pneumococcal disease and to put the plan into action. An intervention program should be developed to promote a positive attitude toward pneumococcal vaccination in older people.
