what should i do? if you're not boosted, get boosted. is that your advice? >> absolutely, chris. there is no doubt about that. the data are overwhelmingly strong in that direction. no doubt about it. >> there are two other things to consider here. one is testing. there is reporting today that the white house is a little concerned about testing capacity. i have already started to see anecdotally that we have higher transmission here in new york city, longer lines for testing. it is very hard to catch up to exponential threads with the linear systems of human markets and institutions as we have seen time and time again with this. are you concerned and prepared to handle the kind of testing search in a world where we have half 1 million cases a day? >> yes. we absolutely are revving up dramatically the testing capability.
