and again, as dr. fauci said, it all depends on getting as many people possible vaccinated. dr. wen, you know, you and i have talked a lot about, you know, for children. what the prognosis is in terms of the time, how long it's going to be before they can get vaccinated. what do you make of what dr. fauci said -- said on that? >> it's sobering. i mean, the timeline keeps on getting pushed back. initially, i thought that for the 6 to 11-year-old group that we would be able to have a vaccine potentially by september or october. now, we're saying maybe in 2021. maybe, in 2022 possibly. i mean, i think at this point, we really need to have another conversation about risk-benefit analysis. as in, there should be no question that the -- if the vaccine is found to be safe and effective, that it should be available for children under emergency-use authorization. we are in a global pandemic. we have the most number of children hospitalized, yet, during this pandemic. we have kids now going back to school, including, in some cases, in schools that are not requiring masks.
