scott gottleib, former fda commissioner, cnbc contributor he also serves on the boards of pfizer and n i thought, scott. as you predicted, i took someone yesterday to get the second shot and it was quiet there a month ago the lines were out the door we're getting close to where everybody that wants one has gotten one and that concerns me because there aren't enough people that have it yet. are we going to start seeing that we need to flip the switch and start inducing people and selling this i don't think the j&j pause helped very much >> look, i'm not concerned i think we're going to continue to chip away at this if you look at the goal that the administration set to try to get 70% of the adults vaccinated by july 4th, that's 175 million adults, right now 150 million are vaccinated they're anticipating getting 25 million vaccinated if you amortize that over 60 days it's about 400,000, 450,000 people vaccinated a day. i think that's probably right. demand will fall off not only because you're getting into softer demand. people who want the vaccine a little less. prevalence will climb.
