Well, we're talking to anybody who will listen.
The simple answer is, as I mentioned earlier, that our costs are $5 a dose. Those costs, 80% of that, $4 of that, are material costs that we have to spend up front. In this environment, where there's so much demand for this type of product, we have to make commitments six, seven or eight months in advance in order to secure these supply chains. If you want 50 million doses, it's simple: 50 million times $4 equals $200 million. If you want to have enough supply for an entire production run of 200 million, that would be $800 million.
The reality is that once we get there, we're going to be able to sell some vaccines and we'll be able to use those revenues to continue to purchase supplies.
I hope that's a straightforward answer.
