"Our main concern is with the pertussis (whooping cough) vaccine. One in 3000 doses cause permanent injury to a child."
James Strain, MD (American Academy of Pediatrics)
as quoted in the United Press.
In 1926, according to historical evidence and the AMA, the pertussis vaccine was known to be associated with neurological damage to children.
It appears little has changed except for more vaccines and more problems.
