I'm figuring that scheduling is not going to be too much of a challenge. While a survey reported in the news this week indicates that about 50% of the US is "interested" in getting the latest shot— which would seem to foreshadow weeks-long waits as with the original vaccine— recall that the actual take rate for the bivalent booster 12 months ago was just 10%. I doubt there will be hugely higher uptake this time around.
