How about the fact that my nephew was severely brain damaged by his DPT shot, and at 23, functions like a toddler?
This is why VAERS database was created and why the vaccine fund was set up under Reagan. Donna Shallala made it VERY hard to get reimbursed from the fund.
The thing is, Japan had the improved DTaP shot over four years b4 it was used in the US, while we used up our supply of DPT.
