Side Effects listed on Tripedia Diptheria vaccine.
"Adverse events reported during post-approval use of Tripedia (diphtheria and tetanus toxoids and acellular pertussis vaccine) 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."

Neuroglycopenia, premature aging, heart disease, type two diabetes, adipocyte hypertrophia, cataract, emphysema, pancreatic damage, kidney stones, inflammation.
What I'm trying to say is that
any substance will have adverse effects on the human body. There's a latin saying "Dosis facit venenum", which holds a lot of truth: any substance, given in inadequate amounts, will be toxic.
Tripedia is not used in Germany - I have therefore looked up the generic drug and checked up on the frequency of the adverse effects that you mentioned. I can only name the frequency for the adverse effects that are listed, that is to say the effects for which a definite causative role has been identified:
A) Anaphylactic Reactions: Frequency <0.01% (less than 1:10000)
B) Cellulitis (local, harmless inflammation): >10% (more than 1:10)
C) Convulsions, Neuropathy, Grand-Mal, Somnolence, Apnea: <0.01% (less than 1:10000)
D) Thrombocytopenia (only observed for a short duration): <0.01% (less than 1:10000)
E) Hypotonia (low grade): <0.1% (less than 1:1000)
Keep in mind that the majority of these reactions are both very rare and
passager. Furthermore, they can be quickly treated (Anaphylaxia with antihistaminergic drugs, epinephrin, etc.; Convulsions rarely need to be treated but can be treated with benzodiazepines; Hypotonia can be treated with sympathomimetics).
The association of SIDS with the named vaccine is something that I find hard to believe - for one, establishing a causative role is very difficult to do and requires a huge study population. Also, the side effect is not listed in the official guidelines, at least not for the generic.
