As China struggles to contain an epidemic caused by a new coronavirus, science is racing to develop vaccines to blunt the outbreak’s impact. Central to the effort is CEPI — the Oslo, Norway-based Coalition for Epidemic Preparedness Innovations — a global partnership created to spearhead development of vaccines in just this type of emergency.
