백신 접종만으로 모든 질병을 완벽하게 제압할 수 없다는 것은 명백한 사실이지만, 사육밀도가 높고 발병 후 특별한 치료대책이 없는 바이러스성 질병이 대부분인 양계질병에 있어서는 질병의 농장유입을 막기 위한 각종 차단방역과 더불어 철저한 백신접종이 최선의 방책일 수 밖에 없다. 백신접종은 어떻게 얼마나 자주 실시하여야 하는가는 각 나라마다 그리고 각 농장마다 다를 수 있으나 국내의 상황과는 다르게 주요질병이 크게 문제가 되지 않는 미국에서의 백신접종 현황은 그 척도를 가늠해볼 수 있는 유용한 자료가 될 것이다. 다음에 분석된 자료는 미국의 육용종계와 실용산란계를 대상으로 백신 프로그램을 조사한 내용으로 1999년 미국내 전체 육용종계의 $91\%$(6,860만수), 산란계는 전체 산란계의 $\58\%$(1억1,000만수)에 대한 백신접종 현황을 반영한 것이다. 주요 백신에 대하여는 1997년과 비교하여 나타내었다.(본 자료는 미국 조지아대학교 수의과대학에서 발행하는 'The Poultry Informed Professional 2000년 3월호[Issue 35]에 개재된 내용을 참고하였다.)

capsular polysaccharide(CPS), alpha toxin과 재조합 fibronectin binding protein (FnBP)으로 구성된 유방염 백신을 개발하여 야외효능실험을 수행하였다. 이 subunit 백신은 비유우 23두와 처녀우 20두를 대상으로 10개월동안 각각 수행되었다. 비유우는 매 3주간격으로 2회 백신접종을 하였으며 대조군은 PBS를 상유방림조절 주위에 피하주사하였다. 처녀우를 대상으로 한 실험에서는 분만 8주전부터 시작하여 매 3주간격으로 2회 비유우 백신접종부위와 동일하게 접종하였다. 접종후 비유우에서는 황색포도상구균에 의한 총유선내 감염율이 대조균에 비해 유의성있게 감소하였으며 (p<0.001) 처녀우에서도 총유선내 감염이 백신 접종균(1.6%)이 대조군(11.7%)에 비해 다음 비유기동안 유의성있게 낮았다. (p<0.001). 비유기동안 백신접종한 젖소의 체세포수는 변화가 없었으며 처녀우에서는 추가접종후 백신접종군에서 대조군의 체세포수에 비해 낮았지만 통계학적으로 유의성은 없었다(p>0.05). 본 실험결과 황색포도구균에 대한 유방염 아단위 백신은 비유우와 처녀우에서 체세포수를 증가시키지 않고 총 유선내 감염율을 낮추어주었다. 하지만 본 실험은 1군데의 목장을 대상으로 하였기 때문에 향후 대규모 목장을 대상으로 하는 유방염 백신의 야외효능실험이 심도있게 이루어져야 한다고 생각된다.

Purpose : To evaluate the number and severity of adverse reactions after Japanese Encephalitis (JE) vaccination in children using different vaccines (inactivated vaccine or live attenuated vaccine) and to determine the ability and safety of the vaccines to provide effective immunization for JE. Methods : From August 2006 to February 2007, we conducted a prospective cohort study of the adverse reactions associated with JE immunization in Korea. We investigated common adverse reactions during the 4 days following immunization using telephone collaborations with four public health centers and nine pediatric clinics. Results : The mean age of children receiving the inactivated vaccines and live attenuated vaccines, respectively, were 1.4 y (range: 1 to 8.5) and 1.7 y (range: 1 to 8.3). The number of children that received the inactivated vaccines was 425 (64.6%). A total of 233 (35.4%) received the live attenuated vaccines. Fourteen children (3.3%) had more than one localized adverse event with the inactivated vaccine, and six (2.6%) had more than one event with the live attenuated vaccine (P =0.607). Systemic adverse reactions occurred in 5.2% vs. 8.2%, respectively, of these groups (P =0.131). Fever was more common in the live attenuated vaccine group than in the inactivated vaccine group on the day of vaccination (P =0.026). Conclusions : The rate of adverse events in our study was even lower than that previously reported. No significant difference in outcomes between inactivated vaccine and live attenuated vaccine was found in JE-immunized children. Fever was more common in the live attenuated vaccine group than in the inactivated vaccine group on the day of vaccination.

The purpose of this study was to vaccinate every year according to the general characteristics of COVID-19, whether to vaccinate every year according to the vaccination experience, whether to vaccinate every year according to knowledge/attitude about vaccination, and negative responses to the vaccinate every year In order to understand the factors affecting the vaccination physician every year by identifying the factors of Statistical analysis is based on general characteristics, variables based on vaccination experience, and knowledge/attitudes related to vaccination. The doctor calculates the frequency and percentage, A square test (-test) was performed, and if the chi-square test was significant but the expected frequency was less than 5 for 25% or more, a ratio difference test was performed with Fisher's exact test. Through multiple logistic regression analysis using variables that were significant in simple analysis, a predictive model for future vaccination and the effect size of each independent variable were estimated. As statistical analysis software, SAS 9.4 (SAS Institute Inc., Cary, NC, USA) was used, and because the sample size was not large, the significance level was set at 10%, and when the p-value was less than 0.10, it was interpreted as statistically significant. In the simple logistic regression analysis, the reason why they answered that they would not be vaccinated every year was that they answered 'to prevent infection of family and hospital guests' rather than 'to prevent my infection' as the reason for the vaccination. It was 11.0 times higher and 3.67 times higher in the case of 'for the formation of collective immunity of the local community and the country'. The adverse reactions experienced after the 1st and 2nd vaccination were 8.42 times higher in those who did not experience pain at the injection site than those who did not, 4.00 times higher in those who experienced swelling or redness, and 5.69 times higher in those who experienced joint pain. There was a 5.57 times higher rate of absenteeism annually than those who did not. In addition, the more anxious they felt about vaccination, the more likely they were to not get the vaccine every year by 2.94 times.

This study conducted a survey using Google Survey targeting 415 college students over the age of 20 to investigate college students' perceptions of the COVID-19 vaccine. As a result, the average result of 'I think the COVID-19 vaccination is necessary' for herd immunity was 3.90, and 65.8% of the 'necessity of vaccination' recognized the 'necessity of vaccination', but 35.4% negatively evaluated 'the safety of the vaccine'. showed. As for the intention to vaccinate against COVID-19, 34.7% said 'I will vaccinate as soon as the order arrives'. This showed that the current COVID-19 vaccination is not positive. As the reasons for not wanting to be vaccinated, 65.3% answered 'adverse reaction to the vaccine' and 25.8% 'distrust of the vaccine itself'. In addition, they perceived the vaccine supply between developed and underdeveloped countries as unequal, and the average was 3.94, indicating that they were afraid of adverse reactions to the COVID-19 vaccine. Therefore, in order to more effectively acquire information about the COVID-19 vaccine, research, platform development, and education on publicity methods through the media frequently used by college students are required.

Mycoplasma gallisepticum (MG) infection results in severe economic loss in the poultry industry. In the previous reports, F strain, one of the MG live vaccine strains, could protect the bird from field infection of MG strains. In this study, efficacy of PoulShot$^{(R)}$ MG-F vaccine againset mycoplasma gallisepticum infection was evaluated for filed application in commercial layers. Commercial layers from two different farms received with PoulShot$^{(R)}$ MG-F, MG-F live vaccine at 9~14 weeks of age. Serological immune response to MG vaccine, the persistency of MG vaccine strain in the upper respiratory tracts and egg production rate were evaluated in the vaccinated, contacted or nonvaccinated flocks. The serological response was first detected at 3 weeks after vaccination (WAV) and persisted for 31 WAV. The MG vaccine strains were also persisted for 31 WAV based on the reisolation and PCR detection. There was no difference between the vaccinated or non-vaccinated flocks in the egg production rate but in the abnormality rate of eggs. Based on the above results, we suggested that the PoulShot$^{(R)}$, MG-F live vaccine was fully immunogenic and had characteristics of long persistence in the upper respiratory trachea which will reduce economic loss caused by MG infection in the layer farms.

This study investigated knowledge about the human papillomavirus (HPV), attitudes toward HPV vaccination, and intention to receive HPV vaccination among marriage-immigrant women, and identified factors associated with intention to receive HPV vaccination. The subjects of this study were 136 marriage-immigrant women in J Province. Data were collected from September 28 to December 21, 2017, and analyzed using SPSS for Windows version 24.0. The participants' knowledge of HPV was low (mean score, 2.74) and their attitude towards HPV vaccination was positive (mean score, 36.66). The factors affecting the intention to take the HPV vaccination included Vietnamese nationality (odds ratio [OR]=2.899, p=.048), desire for education about the HPV vaccine (OR=5.967, p<.001), and a positive attitude towards HPV vaccination (OR=1.083, p=.034). Therefore, educational programs about HPV vaccination targeting marriage-immigrant women are needed. It is also necessary to provide accurate information about the HPV vaccination using various methods, at health care facilities and through mass media.

최근 COVID-19의 백신이 개발되어 접종을 시작했다. 정부는 집단면역 생성을 위해 접종 목표치를 설정하고, 민관합동신속대응팀을 설립하는 등의 조치를 취하고 있다. 하지만 COVID-19의 백신이 다른 백신에 비해 개발 기간이 훨씬 짧을뿐더러, 효과가 입증되지 않아 신뢰를 얻지 못하고 있다. 블록체인은 거래 당사자 간의 거래정보를 네트워크에 참여하는 모든 구성원들이 공동으로 기록, 검증, 저장하는 분산장부 기술로 공인된 제3자 없이도 무결성 및 신뢰성을 확보할 수 있다. 이에 본 논문에서는 COVID-19 백신의 신뢰도를 제고하기 위해 블록체인을 기반으로 한 백신 접종 이력 관리 시스템을 설계하고, 향후 QR코드 등의 방식과 연동하여 백신 여권 등으로의 확장 가능성을 제시한다.
