off on that. i said we don't know because we've seen slopes that went down and then came back up. the best way to assure that we'll be in good shape would be to get more and more people vaccinated. that was misinterpreted as my saying we can't spend christmas with our families. which was absolutely not the case. >> he went on to say he would be spending christmas with his family and encouraged vaccinated people to do the same. that said, certainly a lot of confusion. the cdc is in the process of upgrading guidance for the season. cnn's chief medical correspondent dr. sanjay gupta joins us. he has a brand-new book called "world war c: lessons from the covid-19 pandemic and how to prepare for the next one." it goes on sale tomorrow. i loved "world war z." totally different book. similar title. "world war c" i'm looking forward to. do you agree with dr. fauci about the holidays? how are you approaching the next few months in terms of celebrating covid? >> i am looking forward to them,
