I don’t think it was being less than forthright, just overly conservative with a target of end of July. I like this announcement so much better. There’s a chance we don’t get there and miss the target but I’d much prefer they set an aspirational goal and shoot for achieving it then something that was almost impossible not to make.
I felt that way when Biden initially made the "pledge" of 100 million doses in the first 100 days. At his inauguration, we already were just under 1 million per day -- So it wasn't a very aspirational pledge.
But I take today's announcement as more than aspirational -- It suggests to a high degree of confidence that we will "have enough vaccine by the end of May."
..... of course, vaccine hesitancy may still be a big stumbling block. We will see.
