Also, Andy Slavitt posted an overview of what he thinks will happen:

In the US, cases are still down. But 2 things are worth watching.
-Only 10% of cases are BA2 and since BA2 spreads approx 30% faster than omicron, expect it to follow Europe -About 1/3 of our early warning wastewater sites are showing increases. As we have seen throughout the pandemic, the US haas followed Europe by several weeks in our waves of cases. That may happen again here.
But what happens next is going to be different in every country based on what happened this last year.
The factors that will influence how a rise in cases might look in the US are:
-the proportion of the country with prior omicron infection
-the percentage of non-omicron infected who are vaccinated, or if higher risk, boosted
-the state of US hospitals
-An estimated 45% of the US has had omicron recently. That should be highly protective
-Those fully vaccinated but who haven’t had omicron should be vulnerable to infection from BA2, but largely won’t be hospitalized or worse
Those without prior infection would be at most risk of infection.
Those who haven’t been infected but also aren’t vaccinated or boosted will be at highest risk of hospitalization.
So we could see lots of cases, but an even lower portion of ppl hospitalized than last wave.
We'll see.
I think his final post is telling:
For vulnerable populations— from kids under 5 to those who are medically fragile to those who have chosen not to get vaccinated— things haven’t changed. Only the people around them have.
And in case you're feeling bored and want to see the list of what is considered "medically fragile", check the
CDC. Of note:
Heart conditions
Having heart conditions such as heart failure, coronary artery disease, cardiomyopathies, and possibly high blood pressure (hypertension) can make you more likely to get very sick from COVID-19.
That is ~122 million adults, or close to half of all adults. Seems reasonable.
