This study aimed to identify the vaccination rate for pneumococcus among aged 65 or older, and at the same time to determine the reasons for vaccination or non-vaccination.
The population of this study was aged 65 or older, with a total of 1,150 subjects to be analyzed and a computer assisted telephone interviewing was used. The survey included pneumococcal vaccination status, reasons of vaccination, sources of information on vaccination, reasons for not vaccination, and other related factors.
The vaccination rate for pneumococcus among aged 65 or older was 56.2 percent, lower than 69.0 percent in the U.S. (2017), and 69.2 percent in the U.K. (2019). Among the factors related to the pneumococcal vaccination, the groups with the high vaccination rate were women, low age groups, residents of urban areas, people without a job, people with high education, medical insurance subscribers, married people, and people who have family members. In addition, the groups with high vaccination rates were those with high awareness, those who received recommendations from doctors, those who had vaccination records, those who believed in vaccination effects, and those who saw public service advertisements.
In the future, it is necessary to develop alternatives to accurately manage vaccination records for adults who are not eligible for state support, and regular adult vaccination rates should be calculated so that they can be used as evidence for the country's infection control policy.
