A Grand Mal Seizure

I am writing on behalf of my brother, Peter (aged 74), who can no longer write on his own behalf.

Just a few months after his second shot, Peter suffered a Grand Mal seizure which has left him incapacitated, both mentally and physically.  Within two years, he degenerated into an old man, barely able to attend to his own most basic needs.  He now has dementia. This is a tragedy.  He is my only sibling and I am forced to watch his rapid decline on a daily basis with not even a glimmer of hope in view.
