There are 11 counties in all that have crossed this mark.
Eight of the state's 87 counties fall into this category.
Fewer than half of all vaccine-eligible individuals in these areas have received at least one shot.
More than 8 in 10 residents of that age group have gotten at least one dose.

The figure remains stubbornly unchanged since late June.
