gtpeachI talked to my mom about the vaccine. She had an adverse reaction to a vaccine when she was much younger (like school-aged). It wasn't Bells Palsy, and I can't for the life of me remember what it's called. It has the word "dance" in it, and she basically lost control of her body....
"Saint Vitus Dance":
I'm pretty sure that's the temporary vaccine-induced ailment your mother had.
It sounds exactly like the temporary medication-induced neuromuscular ailment I had in early 2003. That was when the docs had repeatedly injected me with anti-regurgitants after they treated me for food poisoning.
The newer name for St. Vitus' dance is Chorea:
Chorea is characterized by brief, semi-directed, irregular movements that are not repetitive or rhythmic, but appear to flow from one muscle to the next. These 'dance-like' movements of chorea often occur with athetosis, which adds twisting and writhing movements. Walking may become difficult, and include odd postures and leg movements.
The nightmare chorea experience is something that you never forget your entire life. After my chorea, I was able to join a support group with other middle-aged adults who had also had it.
In contrast, your mother was a girl, and at that time the only support available was a few medical professionals and other adults who tried to assure her that she would be fine and it would not happen again. With all that in mind, I can definitely understand why your mother fears what might happen if she has the Covid-19 vaccine.
