What this research studies

You would receive either the HydroVax-CHIKV vaccine or a placebo in a randomized, double-blind dose-escalation format and be followed over time. The study includes clinic visits, safety monitoring for adverse events, and blood draws to measure immune responses. This Phase 1 trial is focused on early safety and whether the vaccine prompts antibody responses that could protect against chikungunya. If results are promising, the vaccine could move into larger trials that enroll more people and test protection.

Who could benefit from this research

Good fit: Healthy adults aged 21 years and older who can attend study visits and are willing to receive vaccinations and blood draws are the intended participants.

Not a fit: People under age 21, pregnant individuals, those with active chikungunya infection, or people with severe immune suppression are unlikely to benefit from participation in this early-phase vaccine trial.

Why it matters

Potential benefit: If successful, this vaccine could provide protection against chikungunya infection and help reduce outbreaks, especially for people in or traveling to affected regions.

How similar studies have performed: Other chikungunya vaccine candidates have produced promising immune responses in early human trials, but no licensed vaccine is yet available.
