The aim of this study was to investigate the factors influencing on influenza vaccination among socio-demographic characteristics and health behaviors. Data of 18,299 adults of age between 19 and 65 years who answered to the survey on National Health and Nutrition and influenza vaccination from 2007 to 2010 was used and analyzed. Overall influenza vaccination rate was 21.7%. Logistic regression analysis revealed that factors influencing on influenza vaccination were an increasing age, a residence in rural area, a high personal income, a low educational level, jobless women, experience of hospital visits, and morbidity of chronic illnesses. In conclusion, influenza vaccination rate in Korea is low and influenced by multiple socio-demographic factors and health behaviors. It is needed to seek a strategy to develop a vaccination program in consideration of factors associated with influenza vaccination.

Annual epidemics of seasonal influenza occur during autumn and winter in temperate regions and have imposed substantial public health and economic burdens. At the global level, these epidemics cause about 3-5 million severe cases of illness and about 0.25-0.5 million deaths each year. Although annual vaccination is the most effective way to prevent the disease and its severe outcomes, influenza vaccination coverage rates have been at suboptimal levels in many countries. For instance, the coverage rates among the elderly in 20 developed nations in 2008 ranged from 21% to 78% (median 65%). In the U.S., influenza vaccination levels among elderly population appeared to reach a "plateau" of about 70% after the late 1990s, and levels among child populations have remained at less than 50%. In addition, disparities in the coverage rates across subpopulations within a country present another important public health issue. New approaches are needed for countries striving both to improve their overall coverage rates and to eliminate disparities. This review article aims to describe a broad conceptual framework of vaccination, and to illustrate four potential determinants of influenza vaccination based on empirical analyses of U.S. nationally representative populations. These determinants include the ongoing influenza epidemic level, mass media reporting on influenza-related topics, reimbursement rate for providers to administer influenza vaccination, and vaccine supply. It additionally proposes specific policy implications, derived from these empirical analyses, to improve the influenza vaccination coverage rate and associated disparities in the U.S., which could be generalizable to other countries.

Background: An inactivated Hantaan virus vaccine (iHV) has been broadly used as a preventive strategy for hemorrhagic fever with renal syndrome (HFRS) by the South Korean Army. After the vaccination program was initiated, the overall incidence of HFRS cases was reduced in the military population. While there are about 400 HFRS cases annually, few studies have demonstrated the efficacy of the iHV in field settings. Therefore, this study aimed to evaluate the iHV efficacy on HFRS severity. Methods: From 2009 to 2017, HFRS cases were collected in South Korean Army hospitals along with patients' vaccination history. HFRS patients were classified retrospectively into two groups according to vaccination records: no history of iHV vaccination and valid vaccination. Vaccine efficacy on the severity of acute kidney injury (AKI) stage and dialysis events were investigated. Results: The effects of the iHV on renal injury severity in between 18 valid vaccinated and 110 non-vaccinated patients were respectively evaluated. In the valid vaccination group, six of the 18 HFRS patients (33.3%) had stage 3 AKI, compared to 60 of the 110 (54.5%) patients in the non-vaccination group. The iHV efficacy against disease progression ($VE_p$) was 58.1% (95% confidence interval, 31.3% to 88.0%). Conclusion: The iHV efficacy against the progression of HFRS failed to demonstrate statistically significant protection. However, different severity profiles were observed between the iHV and non-vaccination groups. Additional studies with larger populations are needed to demonstrate the effectiveness of the iHV in patients with HFRS.

As the COVID-19 vaccination begins, it is necessary to safely store and manage the vaccination history for vaccinated people, as well as provide only the minimal information for the requested purpose, not in the form of all or nothing, to the institution requesting vaccination personal information. This paper proposes a scheme to safely store and manage the people's vaccination records in a non-forgeable blockchain, and to ensure that users provide only the minimal information necessary to the verifier from their vaccination personal information. A user authorizes the verifier to access the information he has consented with by entering the fingerprint on his smartphone, and in this process, no personal information or secrets can be exposed to an attacker. In addition, it is guaranteed that it is neither possible to impersonate the user nor to steal user personal information even in the case of theft or loss of the smartphone, or leakage of information from the vaccination history management institution. Using the scheme, users have no fear on external exposure of personal information and follow-up damage due to excessive information provision by giving out only the minimal information suited to the verifier.

Purpose: This study was conducted to provide basic data for college students living in the Seoul metropolitan area to prevent the spread of infectious diseases and explore countermeasures by identifying the degree of difference with anxiety, stress, and preventive health behavior before and after the COVID-19 vaccination. Methods: Data were collected from the subjects of the study, 192 college students aged 19 to 29 who completed the COVID-19 vaccination in the Seoul metropolitan area. The data were analyzed with the correlation, paired t-test, and independent t-test using the SPSS 27.0. Results: Preventive health behavior, health anxiety, and stress showed the positive correlation before and after the COVID-19 vaccination among the college students. After the COVID-19 vaccination, COVID-19 related stress including fear of infection (d=-0.11±0.09), and difficulty in social distancing (d=-0.21±0.08), and health behavior (d=-0.06±0.44) decreased compared to before the vaccination. Conclusion: Health education and health policies are required to continue preventive health behavior even after the vaccination.

Purpose: The aim of this study was to identify factors related to the vaccination intentions of nursing students before clinical practice. Methods: A descriptive correlational study design was used. The participants were 129 nursing students who were enrolled in one college of nursing in Seoul and were scheduled for clinical training. Data collection was conducted from February 28 to March 7, 2022. The data were analyzed using descriptive statistics, a t-test, ANOVA, Pearson's correlation coefficient, and a latitudinal regression analysis using the IBM SPSS statistics version 26.0 program. Results: The intention to vaccinate showed a significant correlation with vaccination attitude (r=.72, p<.001), subjective norms (r=.68, p<.001), and perceived behavioral control (r=.63, p<.001). The influencing factors on three intent to vaccinate were vaccination attitude (β=.36 p<.001), subjective norms (β=.31, p<.001), and perceived behavioral control (β=.36, p<.001). The explanatory power of these variables was 69.6%. Conclusion: The vaccination rate before the clinical training of nursing students was related to economic burden, a lack of time, and transportation problems that nursing college students experienced during the vaccination process. Therefore, administrative and financial support is needed for improving the vaccination rates of nursing students.

Purpose : In this study, we created a questionnaire and collected answers concerning actual conditions of vaccination and parents' knowledge of vaccination issues, in order to find false knowledge of patients. We tried to give correct information and suggested the role of the pediatrician. Methods : We made questionnaires and collected answers from 466 parents from March 2004 to June 2004. Results : Places of vaccination were pediatric clinics(49.4 percent), health centers(27.7 percent), general/university hospitals(15.0 percent) and other clinics(4.9 percent). We found 38.8 percent of parents thought that the reason for vaccination at pediatric clinics was a belief of speciality, even though there is no difference in the vaccination itself. We also found 15.0 percent of parents thought that there were no differences between pediatricians and other physicians, but 52.0 percent of parents wanted to receive vaccination at pediatric clinics in the future. Our study also found that 62.4 percent of parents wanted to make out a preliminary questionnaire for vaccination. Many parents got vaccination information from vaccination record books(57.9 percent), and 52.6 percent of parents incorrectly believed that Hib vaccination could prevent all kinds of meningitis. Conclusion : Our study suggests that pediatricians need to make efforts to give out correct information. It is necessary to use preliminary questionnaires for vaccination and correct vaccination information should be written on the vaccination record book. Also, there needs to be counselling with parents about weaning, growth and development at the time of vaccination, and to point out the differences between pediatricians and other physicians.

The COVID-19 curve seesawed and reached the fourth pandemic in July 2021. Since the first three waves, the focus has been on achieving herd immunity through vaccination while a lot of manpower is used for quarantine. However, we have not been able to prevent the fourth wave. The causes are thought to be related to people who doubt the safety of the vaccine and refuse it or violate quarantine guidelines such as social distancing. This study examined guidelines for preventing and controlling COVID-19, the accuracy of vaccination-related information, and described quarantine measures including for those who completed vaccination. In conclusion, prevention and vaccination are the most effective countermeasures against COVID-19. We recommend people vaccination with self-quarantine. Also, it is necessary to make large investments to protect and support nurses in future pandemics.
