My late son developed seizures at 6 months shortly after his dPT shot. He had multiple EEGs and was put on phenobarbital which stopped the seizures within a week, although he remained on it until age 2. That was back in the 80s when kids only got a fraction of the vaccines they’re being given now. My pediatrician knew it was problem for some unlucky kids, which is why he didn’t get another dPT shot again.
I’m sorry to hear that.
They’ve know for DECADES that the additives in these shots are not safe, for many.
God rest your son’s soul....and, bless you.
