Objectives: This study aimed to identify the vaccination coverage for hepatitis B among aged 19 or older, and at the same time to determine the reasons for vaccination or non-vaccination. Methods: The survey was conducted through a Mixed-Mode Random Digit Dialing Survey (RDD) method. The survey included hepatitis B vaccination status, reasons of vaccination and non-vaccination, sources of information on vaccination, and other related factors. Results: The vaccination coverage for hepatitis B among adults 19 years of age and older were 38.0%, 32.5%, and 26.9% for the first, second, and third doses. A related factors with high rate of hepatitis B vaccination was women, younger than 65 years of age, rural residents, having a job, highly educated, health insurance subscribers, living with spouse, family members living together. In addition, the vaccination rate was higher in those who was aware of the states recommended adult vaccination, were explained by a doctor about the need for adult vaccination, kept their vaccination records, and recognized that it helped prevent infectious diseases, and had seen promotional materials. Conclusions: In the future, it is necessary to check the antibody retention rate along with the hepatitis B vaccination coverage of adults on a regular basis. In addition, in order to accurately and quickly identify the hepatitis B vaccination coverage, it is necessary to prepare a plan to improve the computerized registration rate to manage adult vaccination records.

In order to examine the efficacy of concurrent vaccination with live and killed Newcastle disease(ND) vaccines two types of each live($B_1$ and LaSota) and killed(gel and oil) vaccines of all commercial origin were administered either alone or simultaneously to day-old broiler chicks having maternal antibody. Live vaccines were given by conjuntival instillation in volumes of 25${\mu}\ell$ containing $10^{6.0}$ to $10^{6.3}$ median embroy infective dose(EH)) while killed vaccines were given in 0.3$m\ell$ volumes subcutaneously at the back of the neck Hemagglutination inhibition(HI) antibodies were determined at weekly intervals until 8 weeks of age and protection rate was determined at 4 and 8 week of age by challenge inoculation with virulent ND virus(NDV). During the 8 weeks experimental period concurrent administration of live and oil vaccine produced the highest level of HI antibody and the most satisfactory protection, whereas concurrent rent vaccination with live and gel vaccine induced poor immune responses. There was no noticeable difference in the efficacy between the live vaccines, Bl and LaSota when simultaneously administered with oil vaccine. Except for oil vaccine, single administration of either live or killed vaccine at day-old produced less than 50% protection at 4 and 8 weeks postvaccination(PV). Oil vaucine alone induced 80% and 70% protection at 4 and 8 week PV, respectively. Concurrent vaccination caused on visible side reaction like respiratory symptoms and did not negatively influence the growth rate of birds until the end of experiment.

This study was done to identify convergence factors influencing the HPV vaccination in female university students. The subjects of this study were 546 female university students. The data were collected through interviews using a structured questionnaire from 5 to 30th of October, 2013. 138(25.3%) reported that they were vaccinated. Religion, ever heard cervical cancer, HPV and cervical cancer vaccination, ever had a pap test, knowledge about HPV vaccination, health beliefs(total), perceived benefit, perceived barrier, cancer preventive behavior(total) and cervical cancer preventive behavior were associated with being vaccinated. In logistic regression analysis showed that the predictors are ever had a pap test(OR=34.67, 95% CI=17.19~ 69.92), perceived benefit(OR=1.45, 95% CI=1.17~1.81) and perceived barrier(OR=1.44, 95% CI=1.27~1.63). It was recommended to make convergence policy supports and education programs reinforcing a pap test and perceived benefit and reducing perceived barriers about HPV vaccination.

This study was undertaken to compare the serological response of dogs to four commercially available combination vaccines and three different vaccination schedules to canine distemper virus (CDV). A total of 120 healthy puppies (20 puppies per group) at 6 weeks of age were randomly assigned to one of four vaccines [C, G, K, and V (or V3) groups] and one of vaccination schedules [V2 and V4 groups]. At six, nine, and 12 weeks of age, puppies in each group were vaccinated with one of four combination vaccines subcutaneously. And puppies in V2 and V4 groups were vaccinated with V vaccine every 2 weeks and 4 weeks, respectively. The serological responses to CDV component of the vaccines were determined by measuring SN titers. The immunogenicity of V vaccine was superior to the other vaccines and optimum vaccination schedule was 3 times vaccination with 3 weeks-interval starting vaccination at 6 weeks of age. Although puppies were vaccinated at 6 weeks of age, the geometric mean CDV titers of puppies in all groups by 9 weeks of age were under the protective level. Therefore, prophylactic measures should include isolation of young dogs from the dog population until vaccination can be expected to provide protection.

The immune responses of commercial layer chickens against Newcastle disease (ND) were compared among different administration methods and times of vaccination during 4 weeks of age. A total of 372 day-old chickens were devided into 4 groups of 93 birds each. Each of 3 groups was received a commercially available B$_1$ live vaccine via drinking water, eye instillation or spray method at one, 14 and 28 days of age. One group was used as an unvaccinated control. At two and 4 weeks after each time of vaccination, 15 birds from each group were challenged with virulent ND virus at the dose of 10$^{5}$ EID$_{50}$ per bird to examine the pretection rate. Ten to 15 birds from each group were bled at two weeks intervals from day old to 8 weeks of age to determine hemagglutination inhibition antibody titer. The protection rate was generally low regardless of the times of vaccination although two or more times vaccination gave higher protection than once vaccination. The low protection was considered due to low titer of the vaccine used since the vaccine titer was less than 10$^{2.5}$ EID$_{50}$ per bird. Spray method gave better protection compared to eye instillation of drinking water method which resulted in lowest response. When birds were challenged majority showed clinical signs on ND between 3 and 6 days after challenge. Death occured one or two days after onset of symptoms. Major clinical signs observed were depression (96%), drowsy(90%), anorexia (84%), diarrhoea (29%), difficult breath (15%) and torticollis (10%). Hemorrhagic lesions on post mortem were seen in duodenum (51%), trachea(36%), illeum (13%), ceacal tonsil (11%), proventriculus (10%) and some other organs.

효과적인 백신 프로그램을 디자인하기 위해서는 질병과 면역에 대한 기본적인 이해가 필수적이다. 면역에 대해서 이해하기 위해서는 크게 체액성 면역과 세포성 면역으로 구분하여 이해하는 것이 유용할 수 있으며, 또한 이 두 가지 기전은 서로 상호협동적으로 작용한다는 사실을 이해하여야 한다. 숙주동물(닭)이 병원체이든 백신이든 일단 항원에 한 번 노출이 되면 이를 기억하는 기억 세포를 생성하여 두 번째 노출되었을 때 폭발적인 면역반응이 일어나도록 한다. 순환항체가 형성이 되면, 이 항체는 난황을 통하여 후대 병아리에게 전달될 수 있다. 면역의 형성은 백신이 가진 항원의 특성과 백신의 타입(생독, 사독)에 따라 다른 방식으로 나타난다. 면역에 대한 기본적인 개념을 충분히 숙지하고 다음의 사항을 고려하면 효과적인 백신 프로그램을 선택하기가 용이하다. (1) 전례 : 어떤 프로그램이 효과적이었는가? (2) 질병 : 어떤 질병이 문제가 되고 있는가? (3) 균주 : 균주의 차이는 중요한가? (4) 관리 : 백신의 사용을 불필요하게 할 효과적인 사양관리가 이루어질 수 있는가? (5) 모체이행항체 : 모체이행항체가 적절한 방어력을 가질 수 있을까? (6) 면역증강효과 : 그 중요성과 접종시기가 숙지되어 있는가? (7) 접종기술 : 접종기술에 문제가 있는데 프로그램이 제대로 효과를 발휘할 수 있을까?

Purpose: The goal of this study is to assess the factors influencing the HPV vaccination of females in their twenties. Methods: The survey was conducted during 2013.11.11-28 with a convenience sample of 488 participants. Results: The mean score of their knowledge about cervical cancer shows 2.54 out of 7. 96.7% and 31.5% of respondents have heard about cervical cancer and HPV, respectively. Only 2.7% are vaccinated by the recommendations from the medical teams. The higher the knowledge scores, the more the subjects are vaccinated. The factors influencing HPV vaccination appear to be prior knowledge about the HPV. Conclusion: The knowledge level is low compared to previous studies. Despite this, the trend of vaccination rate is higher. Medical teams need to promote vaccination. Accordingly, education and promotion are needed for the unvaccinated.

This research attempted to identify the factors associated with the intention of human papilloma virus vaccination among mothers of elementary school daughters. The subject of study is 132 mothers of elementary school students. Data collection was conducted from July 1 to August 30 in 2017, and analyzed using SPSS 23.0 Program. Results showed that 94.7% children of the participants had not been vaccinated, whose reasons were the low knowledge about HPV vaccination, concerns about its side effects, burden for cost. The attitude toward HPV vaccination appeared to be the most important predictor of vaccination, which was followed by perceived behavior control and subjective norm as meaningful predictors, as well. Based on these results, further researches should be conducted to develop educational programs, which are able to offer exact information about the effect and side effect of HPV vaccination, and verify the effectiveness.
