Here the criteria is:
"Are 60 or older who are functionally, mentally, or physically unable to care for themselves OR
Have a court-appointed guardian OR
Have a developmental disability OR
Live in nursing homes, adult family homes, boarding homes, or any other facility OR
Get services from home health, hospice, or home care agencies OR
Get services from an individual care provider or a personal aide".
I don't recall being called a vulnerable adult, but it's probably in my file. Based on the criteria I certainly "qualify".
