볼거리(mumps)는 유행선 이하선염(epidemic parotitis)으로 불리며, 볼거리 바이러스에 의해 유발되는 바이러스성 감염질환이다. 볼거리는 췌장염, 고환염, 청력장애, 난소염, 이하선염 및 뇌수막염과 같은 합병증을 일으킬 수 있다. 볼거리로 인한 중추신경계의 침범은 볼거리로 진단된 환자의 65%에 달한다는 보고가 있으며, 그 중 대부분은 볼거리 뇌막염(mumps meningitis)이다. 이에 반해 볼거리 뇌염(mumps meningoencephalitis)은 볼거리 환자 6000명당 1명의 경우로 매우 드물다고 알려져 있다. 뇌염은 볼거리바이러스의 흔하지 않은 중추신경계의 합병증으로 홍역-볼거리-풍진 예방접종은 볼거리바이러스로 인한 치명적인 합병증을 예방해주고 경과를 가볍게 해준다고 알려져 있다. 저자들은 24세의 젊은 여자가 이하선염을 동반하지 않은 볼거리 바이러스로 인한 급성 뇌염을 경험하여 이에 대한 사례 연구를 하였다. 환자는 예방접종 시기에 맞춰 볼거리 예방접종을 받았다. 본 병원을 내원 시 환자는 인지능력의 저하를 보였으며 치료 후 빠른 회복을 보였고 합병증은 보이지 않았다. 이 연구는 볼거리 바이러스에 대한 2차 접종을 시기에 맞춰 받은 환자에서 이하선염의 동반 없이 뇌염증상이 발생한 환자에 대한 사례 연구이다.

Background: The usefulness of DNA vaccine at priming step of heterologous prime-boost vaccination led to DNA vaccine closer to practical reality. DNA vaccine priming followed by recombinant viral vector boosting via systemic route induces optimal systemic immunity but no mucosal immunity. Mucosal vaccination of the reversed protocol (recombinant viral vector priming-DNA vaccine boosting), however, can induce both maximal mucosal and systemic immunity. Here, we tried to address the reason why the mucosal protocol of prime-boost vaccination differs from that of systemic vaccination. Methods: To address the importance of primary immunity induced at priming step, mice were primed with different doses of DNA vaccine or coadministration of DNA vaccine plus mucosal adjuvant, and immunity including serum IgG and mucosal IgA was then determined following boosting with recombinant viral vector. Next, to assess influence of humoral pre-existing immunity on boosting $CD8^+$ T cell-mediated immunity, $CD8^+$ T cell-mediated immunity in B cell-deficient (${\mu}K/O$) mice immunized with prime-boost regimens was evaluated by CTL assay and $IFN-{\gamma}$-producing cells. Results: Immunity primed with recombinant viral vector was effectively boosted with DNA vaccine even 60 days later. In particular, animals primed by increasing doses of DNA vaccine or incorporating an adjuvant at priming step and boosted by recombinant viral vector elicited comparable responses to recombinant viral vector primed-DNA vaccine boosted group. Humoral pre-existing immunity was also unlikely to interfere the boosting effect of $CD8^+$ T cell-mediated immunity by recombinant viral vector. Conclusion: This report provides the important point that optimally primed responses should be considered in mucosal immunization of heterologous prime-boost regimens for inducing the effective boosting at both mucosal and systemic sites.

Protective efficacy of vaccination with Neospora caninum multiple recombinant antigens against N. caninum infection was evaluated in vitro and in vivo. Two major immunodominant surface antigens (NcSAG1 and NcSRS2) and two dense granule proteins (NcDG1 and NcDG2) of N. caninum tachyzoites were expressed in E. coli, respectively. An in vitro neutralization assay using polyclonal antisera raised against each recombinant antigen showed inhibitory effects on the invasion of N. caninum tachyzoites into host cells. Separate groups of gerbils were immunized with the purified recombinant proteins singly or in combinations and animals were then challenged with N. caninum. Following these experimental challenges, the protective efficacy of each vaccination was determined by assessing animal survival rate. All experimental groups showed protective effects of different degrees against experimental infection. The highest protection efficacy was observed for combined vaccination with NcSRS2 and NcDG1. Our results indicate that combined vaccination with the N. caninum recombinant antigens, NcSRS2 and NcDG1, induces the highest protective effect against N. caninum infection in vitro and in vivo.

Adjuvants are immune enhancers that are often used in vaccination to augment the immune response of a vaccine, thereby enhancing the protective immunity against the targeted disease. In the present study, we used the recombinant protein, such as rRbCC1, this protein was produced from rock bream CC chemokine 1. To verify the adjuvant effects of this recombinant protein, the immune responses of rock bream to Streptococcus iniae (S. iniae) FKC vaccination, which alone or in combination with recombinant protein was analyzed and then also performed experimental challenge with live S. iniae. The result of serum agglutination titres was showed relatively low levels however, the efficacy of FKC vaccine still conferred protection against S. iniae. Moreover, the adverse effects result showed that no statistically significant difference was revealed between high concentration injected and non-injected fish groups, generally. The relative percent survival (RPS) of FKC + recombinant vaccination group was significantly higher than that of vaccinated group with FKC alone. After experimental challenge to the rock bream by injection with live bacteria (S. iniae), the FKC + rRbCC1 vaccination group was showed 87.0% RPS, however, the RPS of FKC alone vaccination was 68.2%. The results indicated that the recombinant protein as an adjuvant had a clear synergism to injection vaccine of rock bream.

COVID-19 vaccines have been developed worldwide in order to prevent the spread of coronavirus infection-19, but some people tend to refuse to be vaccinated against COVID-19. Therefore, we will investigate how people's understanding of COVID-19 vaccines affects their attitude to accept COVID-19 vaccination information. Therefore, the purpose of this study is to examine the determinants that affect the acceptability of COVID-19 vaccine through the informational characteristics of COVID-19 vaccine and the individual health belief theory. This study conducted an offline survey of 215 adult men and women living in Seoul and Gyeonggi-do Province during the period from September 1 to September 10, 2022, and we have conducted a final analysis using a total of 212 questionnaires. The results of our study were as follows. First, among the information characteristics of COVID-19 vaccine, it was confirmed that the amount of information had a significant positive effect on susceptibility, severity, and barriers in health belief theory, respectively. Second, among the information characteristics of COVID-19 vaccine, it was found that the quality of information had a significant positive effect on the susceptibility in health belief theory. Third, susceptibility and barriers in the health belief theory significantly had a positive effect on voluntary attitude and involuntary attitude in acceptance attitude, respectively. And finally, it was found that the severity of the health belief theory had a positive effect on the involuntary attitude in acceptance attitude. The results of this study suggest that policy efforts are needed to make accurate information about COVID-19 vaccine known to the people.

우리나라 질병관리본부는 전염병 예방을 목적으로 국가 필수 예방접종을 정하여 특정 시기에 접종하도록 권장하는데, 대부분의 예방접종이 만 2세 전에 집중되어 있어 필수 예방접종만 투여 받더라도 영아는 14~20회 정도 접종을 받게 된다. DPT (diphtheria, pertussis, and tetanus) 는 제2군 법정전염병인 디프테리아, 백일해, 파상풍 예방을 목적으로 생후 2, 4, 6, 18개월 영아에게 근육주사하게 된다. 근육주사 시 주사 바늘 천자 및 약물 주입에 따른 통증이 유발되는데, 본 연구는DPT 예방접종을 받는 2, 4, 6개월 영아 49명을 대상으로 예방접종 시 유발되는 통증경감을 위해 국소마취용 크림인 EMLA (eutectic mixture of local anaesthetics)와 냉각 스프레이의 통증경감 효과를 조사하였다. 연구 결과 EMLA 적용군이 대조군과 냉각 스프레이 적용군에 비하여 주사 전후 맥박수와 산소포화도에 변화가 거의 없어 생리적 반응에서 통증경감 효과가 있는 것으로 나타났다. 결론적으로 EMLA 적용 군이 통증반응에 대한 생리적 변수, 즉 맥박수와 산소포화도를 정상범주로 유지하는데 있어서 냉각스프레이보다 더 효과적인 중재로 검증되었으므로 향후 DPT 예방접종 시 EMLA 크림의 적용 가능성을 시사하는 바이다.
