Biden's vaccine target should be 200 million in 100 days, not 100 million in 100 days.

I guess with only 235 million adults in the U.S. and a large fraction hesitant about taking the vaccine, 200 million probably isn't possible. But 100 million seems like a lowball.

Also, vaccine production is running at about 2 million doses a day (enough to vaccinate 1 million people), so 100 million in 100 days is probably close to the limit of production capacity unless we approve the Johnson & Johnson vaccine.

BUT, Biden has said he's going to do the "first shots first" thing, which would dramatically expand the number of people who get vaccinated per dose produced, so 🤷

Plus, Johnson & Johnson vaccine is a completely different supply chain, requires only one shot, has shown very promising results, and should be approved within weeks if it works:
