Purpose: The purpose of this study was to investigate the rate of human papilloma virus (HPV) vaccinations among 12-year-old daughters and to analyze factors influencing the mothers' decisions to vaccinate their daughters. Methods: A cross sectional descriptive study was conducted using a convenience sample of 139 mothers. Data was analyzed using SPSS WIN 23.0. Descriptive statistics and a logistic regression analysis were conducted. Results: The vaccination rate of HPV among children was 43.9%. Mothers showed a higher knowledge of the HPV vaccination than of cervical cancer and of human papilloma virus. In self-efficacy scores, the subscores of self-regulation efficacy were higher than self-confidence and task difficulty preference. The factors influencing the vaccination of daughters included the age of the daughters at the time of the vaccination, the provision of information on the HPV vaccine, knowledge of the HPV vaccination, and self-confidence. Conclusion: In order to increase the HPV vaccination rate, it is necessary to provide accurate scientific knowledge to mothers. A variety of intervention strategies should be developed to enhance the confidence of mothers so that mothers who want to provide the HPV vaccination to their daughters are able to follow through and provide the vaccination.

This study was conducted to determine the factors affecting influenza vaccination practices among university students, specially influenza vaccination encouragement and perception of preventability. Questionnaires were distributed to 300 college students from April 30, 2018 to November 30, 2018 and of these, 239 answered the questionnaires were used for analysis. Over the past year, 36.8% of the students were vaccinated against influenza. Encouraging people to get vaccinated was a significant factor that affected the practice of influenza vaccination(p<.001). However, perception of preventability was not significant(p=.853). This study is expected to be an effective guide in developing influenza vaccination programs that encourage vaccination in order to increase the vaccination rate.

Objectives: Immunization is considered one of the most successful and cost-effective public health interventions protecting communities from preventable infectious diseases. The Korean government set up a dedicated workforce for national immunization in 2003, and since then has made strides in improving vaccination coverage across the nation. However, some groups remain relatively vulnerable and require intervention, and it is necessary to address unmet needs to prevent outbreaks of communicable diseases. This study was conducted to characterize persistent challenges to vaccination. Methods: The study adopted a qualitative method in accordance with the Consolidated Criteria for Reporting Qualitative Research checklist. Three focus group interviews were conducted with 15 professionals in charge of vaccination-related duties. The interviews were conducted according to a semi-structured guideline, and thematic analysis was carried out. Data saturation was confirmed when the researchers agreed that no more new codes could be found. Results: A total of 4 main topics and 11 subtopics were introduced regarding barriers to vaccination. The main topics were vaccine hesitancy, personal circumstances, lack of information, and misclassification. Among them, vaccine hesitancy was confirmed to be the most significant factor impeding vaccination. It was also found that the factors hindering vaccination had changed over time and disproportionately affected certain groups. Conclusions: The study identified ongoing unmet needs and barriers to vaccination despite the accomplishments of the National Immunization Program. The results have implications for establishing tailored interventions that target context- and group-specific barriers to improve timely and complete vaccination coverage.

Periodic outbreaks of Newcastle disease (ND) caused by velogenic viscerotropic ND virus (vvNDV) has become a major concern in Korea nowadays. Throughout last epidemic, the winter season in 2000, most chicken flocks infected early, under 2-4 weeks of age, showed high mortality up to 50-100%. Serum samples collected from 201 breeder, 284 layer and 112 broiler chicken flocks were examined to evaluate the efficacy of various vaccination methods and programs routinely used for mass vaccination in the field poultry farms. Despite repeated live vaccination, most poultry flocks vaccinated by drinking water route using nipple water supply system failed to produce solid active immune response to NDV during the growing time. In the present study, we applied the spray vaccination technique using Ulvavac or Desvac sprayer to the experimental poultry flocks and examined the efficacy of live vaccination effects induced by it under field condition. Measurable antibody to NDV as well as early protection against vvNDV challenge were found in poultry flocks vaccinated by spray route. Further, we did not found significant post vaccination reactions caused by spray vaccination if properly administered. These data indicate that the spray vaccination will be safe and reliable mass vaccination method for the prevention of ND.

Since the reservoir of leptospires organism is consisted of a broad spectrum of animals, the best method of prevention is vaccination. The clinical trial of leptospires vaccine conducted on human volunteer for its immunogenicity and safety. Summarized results are as following : 1. The Oral temperature among vaccinated group ranged from $36.7{\pm}0.46^{\circ}C\;to\;37.0{\pm}0.34^{\circ}C$, while in placebo injected group it ranged from $36.4{\pm}0.46^{\circ}C\;to\;36.7{\pm}0.53^{\circ}C$. There was no association between vaccination and fever (p>0.05) 2. Mild local reactions revealed in vaccinees were swelling (50-75% ), Redness($75{\sim}90%$), and induration ($25{\sim}40%$). Placebo injected group revealed only redness in 12.5% in 1st injection and 37.5% in second injection. The duration local reactions on injection site for th vaccinees and place groups disappeared within 48 hours. 3. Generalized Symptoms complained by the vaccinees were myalgia (25%), back pain(15%), headache (15%), pruritus(15%), and abdominal pain(10%), whereas placebo group complained of headache (25%), myalgia(12.5%), back pain(12.5%), pain in eyes(12.5%), abdominal pain(12.5%) pruritus (12.5%) and nausea(12.5%). 4. The serological test(MAT) of vaccinees showed geometric mean antibody titer as follows : a. L. icterohemorrhagiae lai 1 week after 1st vaccination : 22.45 1 week after 2nd vaccination : 111.23 3 week after 2nd vaccination : 266.64 b. L. canicola canicola 1 week after 1st vaccination : 24.62 1 week after 2nd vaccination : 123.92 3 week after 2nd vaccination : 276.55 c. L. icterohemorrhagiae copenhageni 1 week after 1st vaccination : 28.28 1 week after 2nd vaccination : 128.55 3 week after 2nd vaccination : 247.88 Whereas all of the place injected group showed below 1:20 titers. The sero-conversion rate of vaccinees were 100 percent.

Objectives: Influenza is a significant worldwide public health issue. Knowledge and perceptions regarding the flu vaccination are associated with whether individuals obtain the vaccination. The purpose of this study was to examine how such perceptions were related to knowledge and self-efficacy regarding influenza and the flu vaccination in Vietnam and the US. Methods: College students (n=932) in Vietnam (n=495) and the US (n=437) completed a self-administered survey regarding knowledge and perceptions of influenza vaccinations in September and October 2016. Results: Vietnamese participants reported significantly lower levels of awareness about flu risk, higher levels of negative attitudes toward flu vaccination, lower levels of knowledge about the flu and vaccination, and lower levels of self-efficacy than US participants. Higher levels of flu and flu vaccination knowledge and self-efficacy regarding general responsible health practices were associated with lower levels of negative perceptions of flu risk and attitudes toward vaccination. At the same time, self-efficacy regarding responsible health practices was associated with higher levels of awareness of flu risk and lower levels of negative attitudes toward vaccination. Self-efficacy regarding exercise was associated with lower levels of perceptions of flu risk and higher levels of negative attitudes toward vaccination. Conclusions: Vietnam could benefit from influenza education based on this comparison with the US. In both countries, knowledge and self-efficacy were found to be important factors influencing perceptions of influenza risk and vaccination.

Purpose: This study was done to examine mothers' acceptance and its influencing factors in daughters' human papillomavirus (HPV) vaccination to prevent cervical cancer. Methods: From July 20 to August 31, 2010, 220 mothers of unmarried daughters responded to self-administered questionnaires about their acceptance of HPV vaccination for their daughters and the optimal age for HPV vaccination. Descriptive statistics, univariate logistic and multiple logistic regression were used for data analysis with SPSS/WIN 12.0. Results: Mothers indicating their willingness to pay for their daughters to receive HPV vaccination accounted for 61.8%, and willingness with health insurance coverage, 84.5%. Mean optimal age for HPV vaccination was $19.78{\pm}3.96$) years. With self-payment the factor influencing mothers willingness was necessity of HPV vaccination (OR= 30.45, 95% CI=10.33~89.15). With health insurance coverage, income (OR=3.02, 95% CI: 1.19~7.62), necessity of HPV vaccination (OR=15.05, 95% CI=4.15~54.64), concern about HPV vaccine safety (OR=2.99, 95% CI=1.15~7.76), and experience of Pap test (OR=3.16, 95% CI=1.24~8.05) were factors influencing mothers willingness. Other influencing factors were optimal age for HPV vaccination, knowing about HPV (OR=7.66, 95% CI=2.19~26.82), and age of youngest daughter (OR=3.95, 95% CI=1.34~11.68). Conclusion: Financial support is anticipated for low income families in a primary approach to increase HPV vaccination. And focusing on earlier age and concerns about vaccination are necessary to gain mothers' acceptance.

Purpose: The primary prevention for cervical cancer, the human papilloma virus (HPV) vaccination, has been available in South Korea and its importance has been emphasized publicly. The purpose of this study was to investigate the knowledge regarding HPV vaccination and identify the factors associated with HPV vaccination in female university students. Methods: A sample of 200 women among university students in Seoul was asked to answer a questionnaire on HPV-related knowledge and attitude, and influencing factors on HPV vaccination. Results: Among the respondents, 12.0% were HPV vaccinated. Overall HPV-related knowledge was low, and knowledge was not different between the vaccinated and unvaccinated groups. The vaccinated group demonstrated a higher score on the knowledge about the place where people could receive HPV vaccination and the cost of the vaccination than that of the unvaccinated group. The major influencing factor on vaccination was the parent's recommendation and the major barrier for vaccination was the cost of the vaccination. Conclusion: A broadened public campaign is recommended to increase the knowledge and positive attitude towards HPV vaccination for university female students as well as their parents.

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.

The purpose of this study is to identify factors that influence HPV(human papilloma virus) vaccination intention and behavior for mothers with a teenage daughter as the subject of HPV vaccine free inoculation from 2016 based on the theory of planned behavior. For attitude, subjective norm, perceived behavior control, intention, we used a tool modified and supplemented by Hye-Min Park, Hyu-Ei Oh. from June to September 2017, data of 249 people were collected and analyzed by SPSS Statistics 21.0 program. The results of this study showed that the factors affecting the HPV vaccination intention of the subject were attitude, subjective norm, perceived behavior control in order. In addition, the factors influencing HPV vaccination behavior were found to be level of education, subject's vaccination status, recommendation of health care provider, vaccination status of surrounding people, intention etc. Therefore, in order to increase the vaccination rate, we need to find a way to consider the factors influencing vaccination behavior and maximize the vaccination rate.
