Virus-Like Particle Vaccine Protects Monkeys from Chikungunya Virus

An experimental vaccine developed using non-infectious virus-like particles (VLP) has protected macaques and mice against chikungunya virus, a mosquito-borne pathogen that has infected millions of people in Africa and Asia and causes debilitating pain, researchers at the National Institutes of Health have found. Scientists at the National Institute of Allergy and Infectious Diseases (NIAID) developed the vaccine because there is no vaccine or treatment for chikungunya virus infection.
