NCT02532569

Brief Summary

A multi-center, open, phase 4 clinical trial to assess the long-term immunogenicity and safety of fourth administration of Boryung Cell-Culture Japanese Encephalitis Vaccine inj. and to conduct an exploratory investigation on vaccine interchangeability in Korean children aged 6 years who received primary 3 doses with ENCEVAC® or Japanese Encephalitis Vaccine-GCC® inj.

  • 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.

You may not qualify if:

  • 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 received JEV (including live JEV) other than the investigational products administered in the KD287-BR-CT-301study.
  • Children who have had fever (≥ 40 °C) or systemic allergy within 48 hours after vaccination.
  • 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.
