In the school system that both of my children attend, they can and they do.
I took my son to be registered. Part of that registration was to run by the school nurse’s office to have her check the vaccination records. My son was missing a vaccine. The nurse told him to sit down and pulled out a pre-loaded syringe. I asked her how she could do this without my permission and she told me that I gave my permission with the emergency medical form.
My daughter came home with a band-aid on her arm. I asked her what happened and she told me that she had to get the Hep-B vaccine. (We had homeschooled before this and I had declined this shot in the past.)
Again, no permission.
Yes, this does happen in Texas and it happens often.
I am stunned.
This is doesn’t happen in my school district. But, then, I’m in one of the reddest counties in Texas.
