An email: “Whelan’s numbers don’t add up: ‘However, it now appears that we will not even have enough vaccine to protect the 185 million Americans deemed high risk. As of this writing, the available supply of vaccine is about 54 million–for a total population of nearly 300 million Americans.’ There’s no way that over 60% (185 million of 300 million) of Americans are infants, toddlers, pregnant women, the elderly, health care workers and others.” Well, I don’t know: Others could be a pretty big category.
