It is pretty well accepted now that the U.S. based pharmaceutical companies are saying no way to getting this vaccine to market anytime soon.
There was a definite change of tone in today's Press Conference. The CDC head was grilled over comments he made to Wash. Post saying it could be worse in the fall when flu season starts, and he back tracked a bit and said it was more "complicated" if the seasonal flu strain hits at the same time there is a COVID19 resurgence.
But he specifically said they could handle the two together, and that he was hopeful the "vaccine hesitancy" groups would buck up and get their flu shots. Dr. Brix basically said the same thing.
So look for talk to now switch to a Mandatory flu vaccine in the Fall. It is already approved by the FDA.
