My daughter has a demyelinating disorder and this is one of the possible "adverse events" from taking the DTaP. The DTaP was one of the shots she received at 14 weeks of age when started her decline and ended up at the hospital. She now has hippocampal sclerosis (the hippocampus is one of the main organs of learning); she requires 35 hours/week in intensive 1:1 therapy, in addition to school, in order to learn the same material as her age-peers. She also has temporal and frontal lobe seizures, now. If you think having a child is expensive, try adding $60K a year in therapies that your insurance will not cover! And if you feel you already do not have enough time in a day, try adding daily visits to therapists and weekly visits to specialists - and if you choose Public school, days and days of fighting for services to which your child is entitled under the law but refused because the schools have already earmarked the Special Needs funding for other projects...
FWIW, she had the full series of DTaP and still contracted Pertussis (as did most of the school) two years ago...http://www.rxlist.com/tripedia-drug.htm#

"...Additional Adverse Reactions:
· As with other aluminum-containing vaccines, a nodule may be palpable at the injection sites for several weeks. Sterile abscess formation at the site of injection has been reported.3,36
· Rarely, an anaphylactic reaction (ie, hives, swelling of the mouth, difficulty breathing, hypotension, or shock) has been reported after receiving preparations containing diphtheria, tetanus, and/or pertussis antigens.3
· Arthus-type hypersensitivity reactions, characterized by severe local reactions (generally starting 2-8 hours after an injection), may follow receipt of tetanus toxoid.
· A few cases of peripheral mononeuropathy and of cranial mononeuropathy have been reported following tetanus toxoid administration, although available evidence is inadequate to accept or reject a causal relation.37
· A review by the Institute of Medicine (IOM) found evidence for a causal relationship between tetanus toxoid and both brachial neuritis and Guillain-Barré syndrome.37
· A few cases of demyelinating diseases of the CNS have been reported following some tetanus toxoid-containing vaccines or tetanus and diphtheria toxoid-containing vaccines, although the IOM concluded that the evidence was inadequate to accept or reject a causal relationship.37
Adverse events reported during post-approval use of Tripedia vaccine include idiopathic thrombocytopenic purpura, SIDS, anaphylactic reaction, cellulitis, autism, convulsion/grand mal convulsion, encephalopathy, hypotonia, neuropathy, somnolence and apnea. Events were included in this list because of the seriousness or frequency of reporting. Because these events are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequencies or to establish a causal relationship to components of Tripedia vaccine.2
