For the next seven months, the scientist will drive from her home in the Rocky Mountains to a warren of secure biocontainment laboratories nestled next to the foothills to test an experimental coronavirus vaccine. The laborious experiments at Colorado State University are physically and mentally taxing — some people compare the fatigue and exhaustion of working “behind the barrier” of a biosafety level-3 laboratory to a hangover.
