Clinical Trial NCT03343626: Safety, Immunogenicity and Dose Ranging Study of Inactivated Zika Virus Vaccine in Healthy Adult Participants

  • The purpose of this study is to describe the safety, tolerability and immunogenicity of two doses of purified inactivated Zika virus vaccine TAK-426 (PIZV) given 28 days apart.
  • Participants will be followed for 7 days post each dose for tolerability and up to 6 months post-dose 2 for safety. Immunogenicity assessment will be performed at 28 days post each dose and 6 months post-dose 2.
  • In addition, the selected dose group and control group will be followed 24 months post-dose 2 for safety and persistence of immunity.
  • If initial data from ZIK-101 are supportive, Takeda will work to progress into Phase 2 development as soon as possible.
