Pfizer got NO money from the US government and is not connected to Trump in any way, I see what Natt Hancock is saying by couching his optiimismism in words like "it is one step among many".
My key word is "average".
It will be another month before Pfizer has more info beyond a simple press release of some data.
If and when a vaccine is cleared to go, the Government will then be involved in manufacture and distribution. (operation Warp Speed)
