Detailed Description
This is a follow-up study of KD287-BR-CT-301 (ClinicalTrials.gov
identifier: NCT01150942), a phase 3 study to investigate the efficacy and safety of a cell-culture Japanese encephalitis vaccine (ENCEVAC®) compared with that of a mouse brain-derived Japanese encephalitis vaccine (Japanese Encephalitis vaccine-GCC® inj).
Subjects participated in KD287-BR-CT-301 study were to receive 3 doses of Japanese encephalitis vaccine (JEV) assigned by randomization from the age of 12 months and those subjects who completed the 3 doses of JEV are the target population in this study.
The purpose of this study is to investigate the long-term immunogenicity and safety of the booster (fourth) dose of JEV, which will be given as Boryung Cell-Culture Japanese Encephalitis Vaccine inj, proven to be same with ENCEVAC® but manufactured by a different manufacturer.

Description
Inclusion Criteria:
- Parent/guardian (legally authorized representative) has given voluntary written consent to the subject's participation after being fully informed of the purpose, methods, risks, and benefits of the study.
- Male and female children who have completed the primary 3 doses of JEV in the KD287-BR-CT-301study.
- Male and female children reaching at least 6 years of age on the day of booster dosing of JEV.
- Male and female children who are identified to be healthy based on physical examination and medical history.
Exclusion Criteria:
- Children who have acute febrile illness with tympanic temperature of ≥38.0 ℃ on the day of booster dosing of JEV.
- Children who have moderate or severe acute disease (regardless of fever).
- Children who have history of encephalitis, encephalopathy, cerebromeningitis, or convulsion.

- Children who have shown anaphylactic reaction to the investigational products administered in the KD287-BR-CT-301study or who are likely to be allergic to the ingredients of the investigational product.
- Children who have been diagnosed with immunodeficiency such as acquired immune deficiency or who have family history of immunodeficiency.
- Children who have received other vaccines within 28 days before booster dosing of JEV (vaccines to be administered according to the national vaccination program.
- Children who have received immunosuppressive thera-py within 28 days before booster dosing of JEV.
- There is a possibility that immune globulin preparations has not been excreted enough on the day of booster dosing of JEV if children have received such a product.
- Children who are currently participating or planning to participate in other clinical stud-ies during the study period.
- Other ineligible conditions judged at the discretion of principal investigators or subinvestigators.
