"Look what happened—Delta showed up a month from now, relative to a year ago, and then Omicron. In a way, we're still in that kind of world. We don't know yet what the next variant or variants will be."
"Should the FDA approve the [COVID] vaccine for younger than age 5, the data we have right now suggests that [parents are] going to wait. It is still a huge challenge in terms of getting our kids vaccinated. Converting a vaccine into a vaccination is really difficult in this age group."
"I've seen no data which supports the possibility of a fall or winter surge in the US resulting in 100 million cases. No one should make that kind of statement without providing the assumptions behind that number. Could it happen? Sure, but it's more likely if a new variant shows up that is more infectious and more likely to evade existing immune protection than Omicron. Any modeling that looks beyond 30 days out is largely based on pixie dust."
“I don't know what the next shoe is to drop. I don't know. It could be this is as bad as it's gonna get, from here on out, much more mild illness if you have any immunity at all. Or maybe it won't be. I don't know.”
"Every day is a brand new day with this pandemic, relative to the variants. We know that we have strains that are much more infectious, so that, you know, you can't come up with an answer today to say this is where we're at because tomorrow, it could change."
“This virus is so highly infectious that you don’t need to have a lot of exposure to get infected. These variants are 210-mile-per-hour curveballs. What’s going to happen is really in the hands of the virus.”
"One challenge we have with this virus is that we are going to continue to be bombarded by new variants, because this virus changes much faster than the flu. We have to expect the unexpected and, if we don't, we will end up being a day late and a dollar short."
