I am sorry to hear that about your daughter, and thanks for sharing that.
Regarding Bell’s palsy. I’ve looked up Bell’s palsy, and it seems that most common known causes are viral infections (most common ones are herpes simplex(cold sores), flu and cold viruses, HIV, ear infections, herpse zoster (chickenpox/shingles), mumps, mononucleosis/ Epstein-Barr), sometimes bacterial (like Lyme disease). Other causes are suspected, like auto-immune dissorders, diabetes, injuries. But it’s hard to know. Often the cause cannot be pinpointed in a given case. Probably 20 years ago it was even less known about the Bell’s palsy, probably the doctor really didn’t know. Did it at least go away in a short time like the doctor said?
There were very small number of cases in which the cause seems to be the attenuated influenza virus in the nasal vaccines, indeed.
Since you mention this happened after vaccination, it seems likely it was a natural response to the attenuated viruses in the vaccines, if there were any. This palsy is a temporary paralysis of a facial nerve due to inflammation and temporary compression of the facial nerves. I would think it would be unrelated with central neurological damage and learning disabilities. But yes, I believe in rare cases the live virus in FluMist can cause Bell’s palsy, which usually goes away on its own in a few days.
Regarding learning disabilities, which seems to be a bit of a epidemic in US, I believe it is due to some chemicals in the environment/food/etc., and it is a sign of some neurological damage. Definitely I don’t believe it’s genetic per se. Like you said, we all carry the same genes, but there are mutations in the genes that maybe could make some more susceptible to chemicals and such, I am not sure. Maybe some of those mutations have become more prevalent due to some (other) chemicals present, who knows.
