SCIENCE / VACCINE PROCESS DEVELOPMENT

Manki Song, PhD

Manki Song, Ph.D.

Acting Deputy Director General of Science

mksong@ivi.int

Manki Song, Ph.D., Acting Deputy Director General of Science, has had a longstanding interest in public health and threats to health of developing country populations. In the first years of his career, he focused on viral diseases, particularly HIV, HBV and HCV. Most recently, as the Head of the Clinical Research Lab Unit of IVI, he broadened the scope of his studies to include Norovirus and MERS-CoV vaccine development. He looks forward to the continuation of oversight of studies including: field work, clinical medicine, and advanced microbiology, for the betterment of child and general population health. Dr. Song received his B.Sc. from Seoul National University, and M.S. and Ph.D. degrees in viral immunology from Pohang University of Science and Technology (POSTECH) under the mentorship of Prof. Young-Chul Sung. He continued postdoctoral work in Prof. Sung’s laboratory on the development of HBV and HCV vaccines. Dr. Song served as an IVI postdoctoral fellow in 2001 with Prof. Myron Levine at the Center for Vaccine Development (CVD) at the University of Maryland School of Medicine in Baltimore, Maryland. During this period, he focused on the development of new-generation measles vaccines using naked DNA, attenuated Shigella, and Salmonella. Dr. Song has also actively served on steering committees of many academic societies including the Korea Association of Immunologists, the Korean Vaccine Society, and the Korean Dendritic Cell Academic Society. Since 2008, he has acquired a number of Korean government grants (over US$11 million in total) as the principal investigator, and initiated collaboration with Celltrion, a leading Korea-based biotech company, for influenza and pneumonia vaccine development. During this time, he served two years as a Review Board member of the Korea National Research Foundation (Immunology in Medical Science); and since 2015, he has maintained his position as a Program Manager of the state-run Korea Health Industry Development Institute (KHIDI).

Jae Seung Yang

Jae Seung Yang, Ph.D.

Senior Research Scientist, Clinical Immunology

jsyang@ivi.int

Jae Seung Yang joined IVI in 2004 after receiving his Ph.D. in Biology from the Korea Advanced Institute of Science and Technology (KAIST). His research interests focus on the development, standardization and validation of assays for measuring vaccine-induced immune responses, particularly against enteric and respiratory pathogens. He has developed a miniaturized ELISPOT assay which can be used in infants for detecting vaccine-specific antibody-secreting cells in a small (< 1ml) volume of blood, in addition to functional assays for cholera and typhoid vaccines. His laboratory has also contributed to the WHO prequalification of cholera vaccines (Shanchol and Euvichol) by assessing immune responses in several clinical studies.

Currently, his lab is supporting clinical studies of typhoid conjugate vaccine in collaboration with SK Bioscience, and is funded by the Bill & Melinda Gates Foundation (BMGF). Recently, Dr. Yang participated in NIBSC/WHO collaborative studies funded by BMGF, a multi-national project involving seven laboratories from six countries, to evaluate an international standard serum for Typhoid Vi-conjugate vaccines. IVI’s in-house assay has been demonstrated to be the best non-commercial alternative among seven laboratories’ methods for typhoid vaccine clinical trials. As a result, a further collaborative study is planned in 2018 with all participants set to use IVI’s in-house ELISA as the standard method. In addition, MFDS requested that his team lead a project to develop additional human standard serum for a typhoid vaccine.
