I might be that the terms of agreement with Pfizer US and the US government precludes that. I assume it is a wholly owned subsidiary and able to conclude its own agreements. As we saw in other examples with PPE, etc., the US administration of the day was fond of exclusive, America first/America only agreements. Otherwise, dunno.
I can confirm this - it was mentioned on the news last night that the Michigan facility is exclusively supplying the US.
