Purpose: This study aimed to identify the factors influencing COVID-19 vaccination intentions in nurses. Methods: The participants were 184 nurses in Korea. Data were collected using a Google Form online survey method in February, 2021, and analyzed using an independent t-test, one-way ANOVA, Pearson correlation, and multiple regression analysis with the SPSS/WIN 26.0 program. Results: COVID-19 vaccination intention in nurses was correlated significantly with vaccine hesitancy (r = .58, p < .001), risk perception of COVID-19 (r = .22, p = .003), perception of vaccination as a professional duty (r = .59, p < .001), and attitude towards workplace infection control policies (r = .20, p = .007). Vaccine hesitancy (β = .40, p < .001) and the perception of vaccination as a professional duty (β = .44, p < .001) significantly influenced COVID-19 vaccination intention. The model developed in this study explained 50% of the variation in COVID-19 vaccination intention. Conclusion: Improving the perception of vaccination as a professional duty and lowering vaccine hesitancy may enhance nurses' COVID-19 vaccination intention. Above all, it is necessary to provide programs to encourage voluntary recognition of vaccination as a professional duty and develop strategies to reduce hesitancy toward COVID-19 vaccinations.

Purpose: This study aimed to investigate COVID-19 vaccination intention among college students in Korea and verify the factors influencing vaccination. Methods: From April 28 to May 3, 2021, an online survey was conducted on a total of 323 college students. Measures included the 5C scale and the vaccine literacy scale. A logistic regression analysis was performed to identify the factors associated with COVID-19 vaccination intention among students. Results: Among the respondents, 47.7% had the intention to receive the vaccine following the government vaccination plan. Influencing factors of intention to COVID-19 vaccination included the higher level of confidence and collective responsibility and the lower level of constraints and calculation. However, vaccine literacy, socio-demographics, the influence of others, the contents and main source of information about the COVID-19 vaccine, health status and COVID-19-related experiences did not influence the intention to vaccination. The content analysis on self-reported reasons for the decreased vaccination intention resulted in three main categories, including "anxiety about the vaccine", "distrust in the government" and "no need of vaccination." Conclusion: In order to increase COVID-19 vaccination acceptance among college students and form herd immunity, it is necessary to increase the trust in vaccines and emphasize the importance of herd immunity.

Purpose: This study aimed to examine the predictive factors of COVID-19 vaccination behavior by evaluating the moderating effect of perceived behavioral control on the theory of planned behavior. Methods: Data were collected from August 6 to August 31, 2022 from 235 college students (aged 20~29 years) across 12 universities using a structured web-based survey. Statistical analyses were conducted using the SPSS and AMOS software. Results: Attitudes toward COVID-19 vaccination, subjective norms, and intention to be vaccinated significantly influenced COVID-19 vaccination behavior. Attitudes and subjective norms indirectly affected COVID-19 vaccination behavior through intention to vaccinate, whereas intention to vaccinate had a direct effect. The moderating effect of perceived behavioral control on the relationship between subjective norms and intention to vaccinate was significant. Conclusion: Interventions that foster a positive attitude toward COVID-19 vaccination and bolster subjective norms and perceived behavioral control can boost the intention to be vaccinated and facilitate the uptake of COVID-19 vaccination.

Objectives : This study aimed to assess youth perception of COVID-19 vaccination in one Korean Medicine college, to compare according to COVID-19 vaccination. Method : An on-line survey using Google Form was conducted on students enrolled in one Korean medical college. Results : A total of 74 students out of 260 individuals replied, with 43 males and 31 females, 68 (91.9%) were vaccinated (or vaccine reserved), six (8.1%) were not vaccinated. The response rate was 28.5%. All the unvaccinated were intended to receive vaccines in the future. The vaccinated were most concerned about the adverse events. The unvaccinated responded that COVID-19 vaccine was unnecessary, not effective, not safe, and do not recommend vaccination to others compared to the vaccinated. Conclusion : In order to improve the COVID-19 vaccination rate, clear information on the risk of COVID-19 infection and the effects of vaccines should be known through the media.

After the COVID-19 outbreak in 2019, the spread of COVID-19 has not been easily caught despite preventive measures in each country. The spread of COVID-19 has hit the world, especially in the economic and tourism sectors. Countries around the world are easing restrictions on the movement of vaccinated people in preparation for the post-corona era. Under the name of "Vaccine Passport," "Vaccination Certificate," and "Digital Health Pass," vaccination measures are being implemented to allow vaccination recipients to use multi-use facilities. However, there is no international agreement on the movement of countries, and each country has its own immigration policy. In order to return to pre-corona daily life, global agreements must be reached from the movement of vaccinated people between countries, and standards and implementation methods must be determined. This study focuses on the implementation and utilization of vaccination certificates suitable for the COVID-19 era. We will look at the spread of COVID-19 and its international response policies. In the case of COVID-19, we will investigate why vaccination certificate installation should be standardized and how far the current standardization has been discussed, and discuss the characteristics of vaccination certificate installation and considerations. In order for the immunization certificate discussed in the previous chapter to be recognized internationally, institutional and technical considerations are identified and security factors that may occur in each implementation are also presented. Finally, the international recognition case of vaccination certificate is discussed, and the method of installation and utilization of vaccination certificate is proposed. This paper can be used as a policy because of its timeliness in studying the standards of vaccination certificates and considerations for international recognition to restore movement between countries in the spread of COVID-19. In addition, if other infectious diseases occur in the future or similar cases where movement between countries is restricted, it can be used as a reference to support the movement of verified people.

Purpose: This study was conducted to identify factors affecting COVID-19 vaccination and associated side effects among health care workers in a small and medium-sized hospital. Methods: In May 2021, 301 workers out of a total of 670 working in a small and medium-sized hospital in Gyeonggi-do, were surveyed. The small and medium-sized hospital treats patients with COVID-19. Health care workers across different medical institutions responded with self-reported internet questionnaires. Factors influencing COVID-19 vaccination were analyzed via logistic regression. Results: Out of 301 subjects, 89.0% showed an intention to inoculate, and 85.7% were vaccinated against COVID-19. The most frequent reason for vaccination was responsibility as a medical worker. The fear of adverse reactions was the most frequent reason for non-vaccination. Adverse reactions after inoculation occurred in 70.9% of cases, and 30.6% were referred for treatment of adverse reactions. The factors ultimately influencing COVID-19 vaccination were vaccination intention, previous side effects from other vaccinations, occupation, and age. Conclusion: In order to improve the effectiveness of COVID-19 vaccination, a systematic approach is required to determine the risk factors associated with the young age of the administrative staff/personnel, subjects with a history of side effects associated with other vaccines, and health care workers who do not intend to be vaccinated. It is important to develop strategies to improve immunization. In addition, accurate and essential information regarding the side effects of vaccination is needed, along with appropriate education and publicity.

This study is to identify the factors influencing the attitudes, behavior controls, and subjective norms related to COVID-19 vaccination on the intention of preventive behavior in K provincial residents. A total of 232 people agreed to participate in the study. Data were analyzed using descriptive statistics, t-test, ANOVA, correlation, and Hierarchical analysis. As a result of this study, the factors that had a statistically significant effect on the intention to conduct COVID-19 vaccination were perceived behavioral control (β=.39, p<.001) and attitude toward COVID-19 preventive behavior (β=.24, p<.001), followed by subjective norm (β=.24, p<.001). The explanatory power for this was 56.8%. The COVID-19 vaccine is an important means of ending the COVID-19 pandemic and helps prevent infection or worsening of COVID-19 and protect those around you. In the post-COVID-19 situation, it is necessary to improve the intention of vaccination against COVID-19 and to take active measures and strategies. At this point in time when COVID-19 vaccination is becoming more prevalent across the country, we hope that the intent of the COVID-19 vaccination action will translate into a COVID-19 vaccination action.

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.

Objectives: The second wave of coronavirus disease 2019 (COVID-19) cases in Indonesia, during which the Delta variant predominated, took place after a vaccination program had been initiated in the country. This study was conducted to assess the impact of COVID-19 vaccination on unfavorable clinical outcomes including hospitalization, severe COVID-19, intensive care unit (ICU) admission, and death using a real-world model. Methods: This single-center retrospective cohort study involved patients with COVID-19 aged ≥18 years who presented to the COVID-19 emergency room at a secondary referral teaching hospital between June 1, 2021 and August 31, 2021. We used a binary logistic regression model to assess the effect of COVID-19 vaccination on unfavorable clinical outcomes, with age, sex, and comorbidities as confounding variables. Results: A total of 716 patients were included, 32.1% of whom were vaccinated. The elderly participants (≥65 years) had the lowest vaccine coverage among age groups. Vaccination had an effectiveness of 50% (95% confidence interval [CI], 25 to 66) for preventing hospitalization, 97% (95% CI, 77 to 99) for preventing severe COVID-19, 95% (95% CI, 56 to 99) for preventing ICU admission, and 90% (95% CI, 22 to 99) for preventing death. Interestingly, patients with type 2 diabetes had a 2-fold to 4-fold elevated risk of unfavorable outcomes. Conclusions: Among adults, COVID-19 vaccination has a moderate preventive impact on hospitalization but a high preventive impact on severe COVID-19, ICU admission, and death. The authors suggest that relevant parties increase COVID-19 vaccination coverage, especially in the elderly population.

Multiple studies have reported on unilateral axillary adenopathy following coronavirus disease 2019 (COVID-19) vaccination, which is currently recognized as a common finding. Here, we present a series of eight adult patients with reactive axillary lymphadenopathy following COVID-19 vaccination, in whom the follow-up ultrasonography (US) showed resolution of a previously noted unilateral axillary adenopathy. From March 2021 to March 2022, 2,599 consecutive women underwent breast US in Jeju National University Hospital. We identified 10 patients with unilateral axillary lymphadenopathy following COVID-19 vaccination detected on the breast US. The 10 patients were recommended for follow-up US. Two patients were lost to follow-up, whereas the remaining eight patients underwent follow-up US, in whom resolution of the unilateral axillary lymphadenopathy was noted. Radiologists should be aware of evolving guidelines for evaluating and managing axillary lymphadenopathy to avoid false positive biopsies. Recent studies on lymphadenopathy following COVID-19 vaccination show that a prolonged duration until resolution is often observed. Therefore, a follow-up US examination at least 12 weeks after vaccination may be reasonable. Furthermore, management guidelines should include a risk-stratified approach considering both vaccination timing and the patient's overall risk of metastatic disease.
