I still think it’s not the right time yet to get a flu shot. There’s not a lot of flu going around, and historically it peaks in late December.

The hospitalizations per week and ICU admits per week charts look like they are going down, but I don’t believe them: the in-hospital chart looks like it is going up, and the hospitalizations per week and ICU admits per week pretty much always get adjusted upwards later.
