However, I'll go back to my original question: Do you admit that you made a mistake when you signed an agreement with Medicago?
There were already six other companies with vaccines in development, and you invested $323 million in a company that, by its own admission, was going to take much longer to develop its vaccine and was far from certain of the outcome. It took them two years, less time than they had anticipated, but whether it was an unnecessary risk at the time remains to be seen.
