I would characterize it this way: If we didn't take a bet on all seven, then we wouldn't have been able to save those 800,000 lives.
I don't know what kind of price you put on 800,000 lives. I put a pretty high price on 800,000 lives.
The reality is that we didn't have clairvoyance. I don't know what psychic abilities you had, but neither I nor the department had the psychic ability to know which vaccine would work out, so we had to take a bet on all seven.
We knew when we took those advance purchase agreements that not all of them would work out and that, yes, that would cost some money, but that's what we did to make sure that we saved 800,000 lives. That's what we did to make sure that we avoided 1.9 million hospitalizations.
