 And the thing is, back then, you could do this with a lot of speed. These are kind of the Wild West days of vaccine making and research. For example, to do a trial. Offit explained to us, to do a vaccine trial now, you have to sign a 15-page, single-space consent form. Then it was a three-by-five card that said, I allow my child to participate in a blank vaccine trial. And you just filled in, you know, mumps, measles, German measles, and then you signed it. Wow. That was the consent form.
