COPENHAGEN, Denmark, February 14, 2025 – Bavarian Nordic A/S (OMX: BAVA) announced today that the U.S. Food and Drug Administration (FDA) has approved VIMKUNYA™ (Chikungunya Vaccine, Recombinant) for injection, the first virus-like particle (VLP) single-dose chikungunya vaccine in the U.S. for persons 12 years of age and older.
The FDA approved VIMKUNYA under Priority Review, based on results from two phase 3 clinical trials which enrolled more than 3,500 healthy individuals 12 years of age and older. The studies met their primary endpoints, with results showing that 21 days after vaccination, the vaccine induced neutralizing antibodies in up to 97.8% of the vaccinated individuals and demonstrated a rapid immune response starting to develop within one week. The vaccine was well-tolerated and vaccine-related adverse events were mainly mild or moderate in nature1. VIMKUNYA is a VLP vaccine, which means that it uses virus-like particles designed to mimic the chikungunya virus without the ability to infect cells, replicate or cause disease.
“The approval of our chikungunya vaccine is a testament to our unwavering commitment to addressing unmet medical needs and protecting communities worldwide,” said Paul Chaplin, President and CEO of Bavarian Nordic. “As climate change continues to expand the reach of mosquito-borne illnesses like chikungunya, this milestone underscores the importance of cutting-edge solutions to safeguard travelers and vulnerable populations. We are proud to provide the first vaccine specifically approved for the prevention of chikungunya virus in individuals aged 12 and over, offering a critical tool to combat this emerging and growing health challenge.”
