You live in one of the healthiest counties in the country, great access to health care, ranking at the top of nearly every positive public health indicator imaginable. Culturally you will do what you are told. It's not suprising that outcomes in the county are so great. This isn' a dig, it's your reality. It's not most people's reality.
Your county also will see an increase in breakthrough infections, it's inevitable. The increases in breakthrough infections (at least in AZ) are profound. No doubt that vaccines work but will behaviours change over time or will they stay the same amongst the most compliant. People are still going to get sick.
