The currently available stock of smallpox vaccine would be insufficient in the face of an incident of smallpox attack. Thus, new manufacturing methods for smallpox vaccine are urgently needed because previous manufacturing methods using calf lymph are no longer acceptable in the view of current standards. Recently, CJ corporation in Republic of Korea has developed cell-culture derived smallpox vaccine (CJ-50300) which was manufactured by infecting MRC-5 cells. The aim of this clinical trial were to assess safety, reactogenicity, and immunogenicity of CJ-50300 in previously vaccinated healthy volunteers
