half a billion rapid at home tests sent out for free to those who request them. will this make a difference? i suppose the real question is here, what is the gauarantee tht most at risk people ask for the test? you have a disparity over how much people test themselves. >> there are a number of questions. first, do people know how to use these? are they going to be motivated to do it? i'll say my own parents when i said i wanted to rapid test for thanksgiving, my mom's question was, if i'm positive, who is going to cook the turkey. i had to explain if she was positive, we shouldn't be going over. those kind of discussions have to be part of rapid testing. and then, yes, getting people to ask for them is part of this. the last part is will distributing half a billion rapid tests a month from now be sufficient to stem this tide of omicron? we're seeing how quickly it is overtaking the united states now. i worry in a month, it will be a nice to have, but it won't be able to prevent the damage that we're currently undergoing. >> right.
