A Trial of a Walter Reed Army Institute of Research (WRAIR) Live Attenuated Virus Tetravalent Dengue Vaccine in Healthy US Adults

NCT ID: NCT00239577

Last Updated: 2019-02-19

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE2
• Total Enrollment: 86 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2006-04-05
• Study Completion Date: 2007-06-19

Brief Summary

This descriptive study will evaluate the safety and immunogenicity of 5 different formulations of the WRAIR dengue vaccine compared to a placebo.

Detailed Description

Subjects will be randomized into one of 6 groups. One group will receive a placebo vaccine and the others will receive one of 5 different dengue vaccine formations. Each subject will receive two doses six months apart. Study subjects who elect to participate in a mosquito transmissibility component of the study will undergo mosquito feedings during each of the two assigned follow-up visits after vaccine dose 1. All subjects will have 11 venipunctures during 11 visits (i.e., screening plus 10 study visits) over a period of nine months.
