last week for those vaccinated and boosted, there will certainly be breakthrough cases however, you're likely to avoid any type of serious infection from the pandemic. for those who aren't, you're facing death in a very dire winter. one thing to keep an eye on i'm told is what the president says related to testing and potential overflow in hospitals. that's a very serious concern and very real problem on the testing side of things. it will be interesting to see if the president goes any deeper as omicron becomes the dominant variant in the united states today. >> that happened so quick. phil, thanks for your reporting. i want to bring in an epidemiologist. he's currently a professor at cornell medicine. doctor, thank you for being here tonight. i'm happy to see you but not like this because we're learning that omicron is now the dominant covid variant in the u.s. less than three weeks after the very first cases were even detected.
