Phase IIIII Randomized Trial to Assess Safety and Immune Response of BBV87 Inactivated Chikungunya Vaccine in Healthy People Aged 12 to 65 Years

What this Trial Is About

Researchers are evaluating the safety, immune response, and consistency between different vaccine lots of BBV87, an inactivated Chikungunya virus vaccine, in healthy individuals aged 12 to 65 years. This Phase IIIII clinical trial is randomized, observer-blind, and placebo-controlled, aiming to understand how well the vaccine works and its safety profile across multiple study centers. Participants will be randomly assigned to receive one of three lots of the BBV87 vaccine or a placebo. Each subject will receive two doses of 40 micrograms administered as injections into the deltoid muscle of the arm, with the second dose given about 28 days after the first. Safety data will be reviewed by an independent board during the study to ensure participant protection. During the study, participants will attend visits for vaccination and follow-up assessments, including blood tests to measure antibody levels against the virus 28 days after each dose. Researchers will monitor for any adverse events for up to 11 months post-vaccination. The main outcomes measured include immune response levels and the percentage of participants who develop antibodies, along with the safety and tolerability of the vaccine.
