I'm confused by this post. You do know that permanent neurological damage is a documented and confirmed side effect of some vaccines, right?
It is considered to be fairly rare, but it is documented fact. Rand is correct.
People can be permanently injured or die of the diseases vaccinated against. It is a documented fact.
Which is more common? I honestly don't know. Everything in life has risks.
I suppose there are some people who were trapped in cars and burned to death because of seatbelts. I'll take my chances and buckle up.
