Sorry to say, but I'm in that crowd, too.
I remember my classmates with braces and deformities. I also remember the long lines going thru the building, while we all got our shots. So I know I've been vaccinated.
Ohio doesn't, and will not let a child in a school, till they've had all their shots, and approved by a doctor.
I never knew till later in life, why some of my classmates were like they were. I wasn't supposed to ask people, why. It was impolite, mom said. Quite, sad.
