We currently make the flu vaccine in chicken eggs. This is actually a technology that was developed in the mid-1900s. It works pretty well, so vaccine makers just have kept using it. In order to make one vaccine, it takes approximately one egg, so at this site there is almost one million eggs per day that are delivered. On average, it would take about six months for that egg that comes into the door to a final dose vaccine that goes to one of our customers. Along the way, that vaccine spends about 70 percent of its time in quality control testing.
