According to the legal complaint, at an unspecified time after vaccination with diphtheria and tetanus toxoids and acellular pertussis vaccine, the subject experienced "serious and permanent neurological injuries" which were attributed to "toxic mercury exposure".  The following information was received via medical records.  The subject was born to a 33 year old mother, gravida 5 at 36 weeks of gestation via spontaneous vaginal delivery.
