Research points to development of single vaccine for Chikungunya, related viruses

What if a single vaccine could protect people from infection by many different viruses? That concept is a step closer to reality. Researchers have identified 'broadly neutralizing' antibodies that protect against infection by multiple, distantly related alphaviruses -- including Chikungunya virus -- that cause fever and debilitating joint pain. The discovery, in mice, lays the groundwork for a single vaccine or antibody-based treatment against many different alphaviruses.
