would have mattered there, jim. i think this has been a months-long process. we have quadrupled the number of tests in the last couple months but we still need hundreds and hundreds of millions more given the demand. and i think we have got a good thing in -- in these tests. but there won't be enough in many places to get us through the most trying time and particularly the holidays. >> and how concerning is it that the fda is now saying these antigen tests, these at-home antigen tests may be less sensitive to picking up the omicron variant? that's a major piece of the strategy to keep schools open. really, to keep many of the, you know, airports and all these other important parts of our infrastructure open. >> i need to see more before i get too nervous and so i wouldn't just yet. it is a good reminder that almost every tool we have, whether it's a vaccine, a booster, at-home test, respiratory, a mask, isn't 100% perfect.
