  • National Immunization Program (NIP) in korea is regulated by government for effective prevention of infectious diseases since 1954. But the program is only performed in public health center, so many people had various complaints such as inconvenience to use public center, high cost when vaccinated in private medical organization and lack of speciality and registration etc. In this reason, it was very difficult to raise the vaccination rate to 95 percent, infectious disease preventable rate. With this background national assembly and government try to expand the NIP coverage both public health center and private medical organization with increasing budget from 2009. So in this paper an overview and preparation of Korean pediatrician according to the expanding plan of NIP are described.

  • The potential of Streptococcus iniae glyceraldehyde-3-phosphate dehydrogenase (GAPDH) as an antigen for a subunit vaccine was investigated using a zebrafish model. The recombinant S. iniae GAPDH was purified using His-tag column chromatography, and antisera against the recombinant GAPDH (rGAPDH) were produced by intraperitoneal immunization of rats. By immunization with S. iniae rGAPDH, the survival rates of zebrafish against an S. iniae challenge increased, suggesting that GAPDH would be an antigen capable of inducing protective immune responses in fish. Furthermore, we demonstrated using Western blotting, that the antisera against rGAPDH of S. iniae had cross-reactivity with GAPDH from Streptococcus parauberis and Lactococcus garviae, which are also culprits of streptococcosis in cultured fish in Korea. These results suggest that S. iniae GAPDH may be used as an antigen for the development of a subunit vaccine against streptococcosis caused by diverse cocci in cultured fish.

  • Following the Five Year Measles Elimination Program, measles has been declared eliminated from the Republic of Korea since 2006. However, there remain challenges related to the surveillance of measles in the postelimination phase. Even though the routine surveillance system has revealed a gradual decrease in the number of reported cases since 2002, 4 resurgences have occurred, notably due to outbreaks. Because vaccine-modified measles is becoming widespread due to high vaccination coverage, conducting laboratory confirmation in each case becomes important. Moreover, susceptible individuals with measles have been identified through seroprevalence studies. Lastly, the efforts to improve the timeliness of measles reporting have led to the establishment of an active laboratory-based surveillance network, which has shortened the interval between diagnosis and notification. In these circumstances, searching for more sensitive and effective surveillance measures is important for maintaining the elimination status and preventing future outbreaks of measles in Korea.

  • Lifetime Health Maintenance Program(LHMP) or Koreans is the Korean guide to clinical preventive services which include screening for chronic diseases, counseling and immunization. The Korean Task Force on the LHMP vigorously reviews evidence for interventions to prevent over 50 different illnesses and conditions which are important in Korea. The problems addressed in this program are common ones seen every day by primary care physicians in Korea: cardiovascular, infectious diseases, gastrointestinal and endocrine diseases, cancers, alcohol and smoking, and many others. Primary care clinicians have a key role in screening for many of these problems and imunizing against others Of equal importance, however, is the clinician's role in counseling patients to change unhealthful behaviors related to diet, smoking, exercise, injuries, and sexually transmitted diseases The recommendations are grouped by age, sex, and other risk factors.

  • In the present study, we investigated the protection conferred by a live attenuated Salmonella enterica serovar Typhimurium (ST) strain against Salmonella Typhimurium, Salmonella Gallinarum (SG), and Salmonella Enteritidis (SE) infection in layer chickens. Birds were orally primed with the attenuated ST strain at 7 days of age and then boosted at 4 weeks post prime immunization (PPI). Sequential monitoring of plasma IgG and mucosal secretory IgA (sIgA) levels revealed that inoculation with ST induced a significant antibody response to antigens against ST, SE, and SG. Moreover, significant lymphoproliferative responses to the 3 Salmonella serovars were observed in the immunized group. We also investigated protection against virulent ST, SE, and SG strain challenge. Upon virulent SG challenge, the immunized group showed significantly reduced mortality compared to the non-immunized group. The reduced persistence of the virulent ST and SE challenge strains in the liver, spleen, and cecal tissues of the immunized group suggests that immunization with the attenuated ST strain may not only protect against ST infection but can also confer cross protection against SE and SG infection.

  • To optimize the immunological efficacy of CFC-101, an outer-membrane protein vaccine purified from relatively less pathogenic 4 different Pseudomonas aeruginosa strains, we investigated to establish its dose, administration route, interval and frequency of vaccination in mice. As expected, the 4 CFC-101 producing strains were less pathogenic than the challenging organism, P. aeruginosa GN11189. CFC-101 completely protected the death caused by P. aeruginosa at above 0.05 mg/kg vaccinized by 3 times with 7-day intervals. At the optimally effective dose of 0.2 mg/kg of CFC-101, at least 3 immunizations were necessary for complete protection against P. aeruginosa-induced death. If immunized 3 times, the immunization interval could be shortened up to 2 days to acquire the best protection against P. aeruginosa. CFC-101 was effective either by intraperitoneal, subcutaneous or intramuscular but not by oral administration. The present results show that the newly developed Pseudomonas vaccine, CFC-101, is highly effective for the protection from death caused by pseudomonal infections.

  • Liposome-entrapped atypical Aeromonas hydrophila antigen was prepared to investigate the potential protective efficacy for A. hydrophila infection. Carp (Cyprinus carpio) were immunized orally with liposome-entrapped A. hydrophila antigen. After immunization, significantly more antigen-specific antibodies were detected in serum, intestinal mucus and bile than non-immunized control group. The immunized carp were then challenged by immersion with $1{\times}10^{6}$ cfu/ml of A. hyrdophila for 60 min. Of the eight non-immunized carp, three carp died (62.5% survival), whereas five out of six (83.5%) of the immunized survived. Furthermore, development of skin ulcers was significantly inhibited in carp immunized with liposomes containing A. hydrophila antigen. These results suggest that liposomes containing A. hydrophila antigen have a potential for induction of protective immune responses against atypical A. hydrophila infection and also suggest the possibility of developing a vaccine that may ultimately be used for prevention of fish diseases.

  • The adjuvant effect of a muramyl dipeptide (MDP) derivative, MDP-Lys(L18), on enhancing of antitumor immunity induced by X-irradiated tumor cells against highly metastatic B16-BL6 melanoma cells was examined in mice. Mice immunized intradermally (i.d.) with a mixture of X-irradiated B16-BL6 cells and MDP-Lys (L18) [Vac+MDP-Lys (L18)] followed by an intravenous (i.v.)inoculation of $10^4$ viable tumor cells 7 days after immunization, showed a significant inhibition of experimental lung metastasis of B16-BL6 melanoma cells. The most effective immunization for the prophylactic inhibition of tumor metastasis was obtained from the mixture of $100{\;}\mu\textrm{g}$ of MDP-Lys (L18) and $10^4$ X-irradiatied tumor vaccine. Furthermore, immunization of mice with Vac+MDP-Lys(L18), 3 days after tumor challenge, resulted in a significant inhibition of lung metastasis of B16-BL6 melanoma cells in an experimental lung metastasis model. Similarly, the administration of Vac+MDP-Lys(L18), 1 or 7 days after tumor removal, markedly inhibited tumor metastasis of B16-BL6 in a spontaneous lung metastasis model. When Vac+MDP-Lys (L18) was i.d. administered 3 days after subcutaneous (s.c.) inoculation of tumor cells ($5{\times}10^5/site$) on the back, mice treated with Vac+MDP-Lys(L18) showed inhibition of significantly tumor growth on day 20. These results suggest that MDP-Lys (L18) is able to enhance antitumor activity induced by X-irradiated tumor vaccine to reduce lung metastasis of tumor cells, and is a potent immunomodulating agent which may be applied prophylactically as well as therapeutically to treatment of cancer metastasis.
