The patient experienced rash/ urticarial type of rash on 08Sep2016 with outcome of not recovered and fever on 06Sep2016 at night with outcome of recovered. Rash was considered medically significant, while fever was considered a non serious event. The patient underwent lab tests and procedures which included body temperature: 102 Fahrenheit on 06Sep2016 and 98.6 Fahrenheit on 09Sep2016. Therapeutic measures were taken as a result of both events and included TYLENOL, probably 80 mg and BENADRYL. After taking paracetamol the fever never returned. The patient did not visit physician office due to fever. On 07Sep2016 the patient was fine, happy as a clam. On 08Sep2016 the patient developed a urticarial type of rash. The rash faded, then, on 09Sep2016 was full blown again. The baby was still happy as a clam and had no temperature on 09Sep2016, however the urticaria was quite impressive. The patient visited the physician due to rash. The reporting physician gave the baby diphenhydramine on 09Sep2016. He called the allergist and was waiting for them to call him back. The rash was on the front of both thighs and the back of the right upper arm. It was raised red blotches that were hive-like. The rash had started in one small area on the right thigh.  The patient will not be given pneumococcal 13-val conj vac (dipht crm197 protein) again until it is determined if the rash is a true allergic reaction. The physician was assuming the reaction was due to pneumococcal 13-val conj vac (dipht crm197 protein), not haemophilus influenza type b vaccine.
