Evaluating a new dengue vaccine in healthy adults.

A PHASE 2, RANDOMIZED, DOUBLE-BLIND, PLACEBO CONTROLLED, DOSE-RANGING STUDY TO COMPARE THE SAFETY AND EFFICACY OF 3 DOSE LEVELS OF AV-1 IN HEALTHY ADULTS CHALLENGED WITH A CONTROLLED HUMAN INFECTION S

NIH-funded research Johns Hopkins University · NIH-11076168

This study is testing a new dengue vaccine called AV-1 to see how safe and effective it is for healthy adults, and participants will either get the vaccine or a placebo before being exposed to the dengue virus to help find the best dose for future use.

What this research studies

This research investigates the safety and effectiveness of a new dengue vaccine candidate called AV-1 in healthy adults. Participants will be randomly assigned to receive either the vaccine at different dose levels or a placebo, and will then be exposed to a controlled dengue virus infection. The study aims to assess how well the vaccine works and its safety profile through careful monitoring and analysis of participants' responses. This approach helps determine the best dose for future use in larger populations.

Who could benefit from this research

Good fit: Ideal candidates for this research are healthy adults who are willing to participate in a clinical trial and meet specific eligibility criteria.

Not a fit: Patients with a history of severe allergic reactions to vaccines or those with compromised immune systems may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to a safe and effective vaccine against dengue fever, potentially reducing the incidence of this disease.

How similar studies have performed: Previous research has shown promise in developing vaccines for dengue, indicating that this approach has potential based on earlier successes.
