NCT03343626

Brief Summary

The purpose of this study is to describe the safety, tolerability and immunogenicity of two doses of purified inactivated Zika virus vaccine (PIZV) given 28 days apart. Three different vaccine doses containing different protein concentrations (2, 5 or 10 microgram \[mcg\]) each, will be given as 2 dose schedule to flavivirus naive and primed healthy adults. 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 till 24 months post dose 2 for safety and persistence of immunity.
