Thanks for the additional data-point. That 18% difference could very well make the difference.
I'll be keeping an eye on your higher-vaccination rate and how it works out in your city. I've been trying to tell my coworkers / people around me to get vaccinated (and boostered) but not everybody would listen.
EDIT: The state's average is like 80% total population. I live in an area with far below the state's average in regards to vaccinations.
I think 62% vs. 80% could be a big enough delta to explain the difference here versus your town.
