In India, cervical cancer is the most common woman-related cancer, followed by breast cancer. The rate of cervical cancer in India is fourth worldwide. Two vaccines, Gardasil and Cervarix, both targeting HPV-16 and 18 which account for 70% of invasive cervical carcinomas, are licensed in the United States and numerous countries worldwide. Both vaccine formulations have shown excellent efficacy with minimal toxicity in active female population but numerous questions arise in vaccinating like cost effectiveness, lack of proven efficacy against other HPV strains, social acceptance of HPV vaccination and other ethical issues. The main objective of this study is to emphasis the advantages and disadvantages of the vaccination in India.

2003년 5윌 26일부터 29일까지 4일간 포항시 기계면 지역 주민 602명과 청송군 지역 주민 965명 등 총 1,567명을 대상으로 인플루엔자 예방접종실태 및 인지도에 관한 개별면접 설문조사를 실시하였다. '인플루엔자 예방접종은 65세 이상이 무료접종 대상이다'라는 질문에 대하여 '그렇다'는 844명(90.6%)이 응답하여 대부분이 올바르게 인지하고 있었다. '인플루엔자 예방접종은 매년 맞아야 한다'라는 질문에 대하여 '그렇다'는 845명 (86.0%)이 응답하여 대부분이 올바르게 인지하고 있었다. '인플루엔자 예방접종을 맞으면 감기가 예방된다' 라는 질문에 대하여 '아니다'는 224명(20.8%) 응답하여 대부분 잘못 인지하고 있었다. '인플루엔자 예방접종을 맞으면 인플루엔자에 걸린다' 라는 질문에 대하여 '아니다'는 713명 (80.2%)이 응답하여 대부분이 올바르게 인지하고 있었다. '인플루엔자 예방접종은 100% 예방효과가 있다'라는 질문에 대하여 '그렇다'는 604명(65.%)이 응답하여 반수 이상이 올바르게 인지하고 있었다. '유행 시 모든 사람이 인플루엔자 예방접종을 해야 한다'라는 질문에 대하며 '아니다'는 148명(15.7%)이 응답하여 대부분 잘못 인지하고 있었다. 연도별 인플루엔자 예방접종률은 2000년도 23.5%, 2001년도 28.3%, 2002년도 36.8%이었다. 2002년도의 연령에 따른 접종률은 65세 이상이 63.1%, 50세 이상 64세 이하가 33.2%, 40세 이상 49세 이하가 14.2%, 40세 미만이 12.9%이었다. 2002년 예방접종 장소로는 보건소가 128명(53.6%), 병의원이 89명(37.2%)이었다. 2002년 11월부터 2003년 3월까지 독감 여부 조사에서 예방접종군과 비접종군 사이에 유의한 차이는 없었으나, 65세 이상 연령군에서 접종군이 89.6%가 걸리지 않았다고 응답했고 비접종군은 83..2%가 걸리지 않았다고 응답하여 집종군에서 독감 발병률이 낮았다. 전종군에서 예방접종을 실시한 이유는 '보건소 접종 연락 권고'가 223명(34.4%)으로 가장 많았고, 비접종군에서 예방접종을 실시하지 않은 이유는 '건강해서'가 258명(27.3%)으로 가장 많았다. 2003년에 531명(52.8%)이 반드시 인플루엔자 예방접종을 시행하겠다고 응답하였다. 많은 사람들이 인플루엔자 예방접종에 대한 잘못된 인식을 가지고 있어 이에 대한 올바른 홍보 활동이 필요하다. 그리고 2002년도 65세 이상의 접종률은 63.1%, 50-64세군의 접종률은 33.2%로 50-64세군의 접종률을 향상시킬 필요성이 있다. 이들도 65세 이상 사람만큼 인플루엔자에 취약한 집단일 수 있기 때문이다. 본 조사는 표본추출 조사는 아니었지만 인플루엔자 유행에 있어 취약하다고 할 수 있는 농촌 지역주민들의 인플루엔자에 대한 인지도, 접종실태를 조사하였고, 이를 통하여 인플루엔자 예방정책에 기초 자료로 사용될 수 있다는 점에서 의의가 있다고 생각한다.

Toxoplasmosis is an opportunistic infection caused by the protozoan parasite Toxoplasma gondii. T. gondii is widespread globally and causes severe diseases in individuals with impaired immune defences as well as congenitally infected infants. The high prevalence rate in some parts of the world such as South America and Africa, coupled with the current drug treatments that trigger hypersensitivity reactions, makes the development of immunotherapeutics intervention a highly important research priority. Immunotherapeutics strategies could either be a vaccine which would confer a pre-emptive immunity to infection, or passive immunization in cases of disease recrudescence or recurrent clinical diseases. As the severity of clinical manifestations is often greater in developing nations, the development of well-tolerated and safe immunotherapeutics becomes not only a scientific pursuit, but a humanitarian enterprise. In the last few years, much progress has been made in vaccine research with new antigens, novel adjuvants, and innovative vaccine delivery such as nanoparticles and antigen encapsulations. A literature search over the past 5 years showed that most experimental studies were focused on DNA vaccination at 52%, followed by protein vaccination which formed 36% of the studies, live attenuated vaccinations at 9%, and heterologous vaccination at 3%; while there were few on passive immunization. Recent progress in studies on vaccination, passive immunization, as well as insights gained from these immunotherapeutics is highlighted in this review.

The purpose of this study was to examine antibody titers to structural protein (SP) of the foot-and-mouth disease (FMD) virus after vaccination in animals of the Seoul zoo. After the initial inoculation of FMD vaccine to the susceptible animals of the zoo, a total of 235 blood samples were collected from 42 species of zoo animals during treatment or necropsy. All samples were tested by using enzyme-linked immunosorbent assay (ELISA). The overall positive rate of SP antibodies against FMD virus was 94.0% (221/235). However, the positive rates varied according to animal species. The results of positive rates in 30 species were 100% but in 12 species were 50-94.7%. We showed that most animals that have received FMD vaccine in Seoul zoo have been reached to the level of herd immunity against FMD virus after the vaccination. To the best of our knowledge, this study would be the first report for monitoring the vaccine-induced SP antibody titers against FMD virus after vaccination in various zoo animal species in Korea.

Objectives: The pandemic caused by coronavirus disease 2019 (COVID-19) has exerted an unprecedented impact on the health of populations worldwide. However, the adverse health consequences of the pandemic in terms of infection and mortality rates have varied across countries. In this study, we investigate whether COVID-19 mortality rates across a group of developed nations are associated with characteristics of their healthcare systems, beyond the differential policy responses in those countries. Methods: To achieve the study objective, we distinguished healthcare systems based on the extent of healthcare decommodification. Using available daily data from 2020, 2021, and 2022, we applied quantile regression with non-additive fixed effects to estimate mortality rates across quantiles. Our analysis began prior to vaccine development (in 2020) and continued after the vaccines were introduced (throughout 2021 and part of 2022). Results: The findings indicate that higher testing rates, coupled with more stringent containment and public health measures, had a significant negative impact on the death rate in both pre-vaccination and post-vaccination models. The data from the post-vaccination model demonstrate that higher vaccination rates were associated with significant decreases in fatalities. Additionally, our research indicates that countries with healthcare systems characterized by high and medium levels of decommodification experienced lower mortality rates than those with healthcare systems involving low decommodification. Conclusions: The results of this study indicate that stronger public health infrastructure and more inclusive social protections have mitigated the severity of the pandemic's adverse health impacts, more so than emergency containment measures and social restrictions.

Objectives : During March-May, 2000, a measles outbreak occurred at Youngduk, Korea. This county is divided into two areas with different historical and socioeconomic background. The outbreak occurred in one of these areas. We conducted a comparative epidemiologic study on the two areas in order to evaluate the factors related to the epidemic. Materials and Methods : We selected two groups, grades 3 and 5 in a primary schools in each area. We investigated outbreak-related factors using parent-questionnaires, the vaccination history from the student's health record and the records concerning the recent measles-outbreak from the local health center. Serologic test on measles-IgG and -IgM antibody was done. Results : The infection rate was 31.5% for the epidemic area and 3.7% for non-the epidemic area according to clinical or serological criteria (p<0.001). No difference was seen in the measles vaccination rate, residence at the time of vaccination or past measles infection history between the two areas. In the epidemic area, the attack rate for the 4-6 year-old MMR booster group(20.5%) was higher than the non-booster group(32.4%), but was not found significantly. Vaccine efficacy was 29.6% in the epidemic area and 87.0% in the non-epidemic area (p<0.001). The IgG level and positive rate were significantly different between the two areas (median 10727 IU/ml, 98.9% in epidemic area; median 346 IU/ml, 85.9% in the non-epidemic area, p<0.001). However, the IgG level and positive rate between the measles-cases and non-cases were not significantly different. Conclusions : This outbreak took place in mostly vaccinated children. These results suggest that a reduction of herd immunity for immunity failure after vaccination may be one of the feasible factors related to the outbreak pattern in the two areas. The results of the IgG level and positive rate suggest that re-establishment of a normal value for IgG level and of a qualitative method for IgG are needed.

The purpose of this study was to evaluate comparatively the content of the Expanded National Immunization Program according to the provision method between 2005 and 2006 in Korea. We assessed the impact of the mutually exclusive vaccination policy using the result reports of the 2005 and 2006 Demonstration Project and the related references by the content analysis. The public health centers paid vaccination fees to the private clinic and hospital in the 2005 Demonstration Project in Daegu metropolitan city and Gunpo city. But, the public health centers directly supplied free vaccination services to the children in the 2006 Demonstration Project in Gangneung city, Yangsan city, and Yeongi-gun. The total budgets of 2005 and 2006 Demonstration Project were 6.57 billion won and 0.65 billion won, respectively. The computerized registration rates and timeliness rates of administration of each vaccination had improved all in the 5 Demonstration Project regions. However, the computerized registration rates of most vaccination in Gunpo city were higher than those in the 2006 Demonstration Project regions except hepatitis B. Especially, the computerized registration rate of BCG was 48.3%, but the BCG coverage rate by the follow-up telephone survey was 99.8% in Daegu metropolitan city. The community parents in all the regions were satisfied because of expanding financial and geographical access to immunization coverage. In conclusions, from the aspect of the main outcomes, the implementation of two different financial immunization aids appears to be widely accepted among these parents and to have had an impact on vaccination coverage. In the future, the government must try to enact that the national immunization policy including under-immunised or incompletely immunised groups would be achieved by the affordable method of the public-private dynamics.

Background and Objectives: The Herpes Simplex type 2 Defective Infectious Single Cycle virus (DISC virus) is attenuated virus originally produced as viral vaccines but are also efficient gene transfer vehicle. The main goals of this study were to examine the efficiencies of the gene transfer using DISC vectors for various head and neck squamous cell carcinoma cell lines and to evaluate the efficacy of vaccination with DISC virus carrying a immunomodulatory genes (GM-CSF) as cancer therapy in a organotopic oral cavity squamous cell cancer model. Materials and Methods : We determinated the gene transfer efficiency of DISC virus by x-gal stain method and proved gene and protein expression of DISC-GMCSF transfected SCCVII cells by RT-PCR and ELISA method. Also we evaluated the ex vivo vaccination effects of SCCVII/GMCSF (DISC-GMCSF transfected SCCVII vaccine) vaccine on preventing the recurrence of micro-residual tumor. After the vaccination of SCCVII/GMCSF, specific cytotoxic T-cell responses was evaluated by CTL assay. Results: At an MOI of 10 DISC virus showed 64-88% of transfection rates in various head and neck squamous cancer cell lines. SCCVII cells transduced by DISC virus vector (MOI=10) carrying the GM-CSF gene, produced 4.5 nanogram quantities of GM-CSF per $10^6$ cells. In vivo vaccination using tumor cells transduced ex vivo with DISC-GMCSF resulted in better protection rate against subsequent tumor recurrence in organotopic oral cavity cancer model. Although tumor free survival rate was not statistically significantly increased in vaccination group (p=0.078), tumor specific cytotocic T-cell responses were significantly increased in SCCVII/GMCSF vaccination group. Conclusion: These data demonstrate that; 1) The DISC virus vector is capable of efficient gene transfer to various head and neck squamous cancer cell lines, 2) GM-CSF secreting genetically modified tumor vaccine (SCCVII/GMCSF) efficiently protected against tumor recurrence in organotopic micro-residual oral cavity cancer model and produced tumor specific cytotoxic T-cell response. DISC virus-mediated, cytokine gene transfer may prove to be useful as a clinical therapy for head and neck cancers.
