Chikungunya virus is a mosquito-borne infectious disease that causes severe arthritis. Since re-emerging in 2004, it has infected millions of people. Attempts to develop vaccines had only limited success until recently, when researchers developed a vaccine using virus-like particles (VLPs). The VLP vaccine protected macaques from Chikungunya viral infection.
