Clinical narrative: This 13-month-old female subject was enrolled in a blinded study. The subject received the 1st dose of PRIORIX vs MMR II+VARIVAX (+ PREVNAR) (subcutaneous) on 19th March 2015. Concurrent medical conditions included upper respiratory infection, fever, and allergic Urticaria. Concomitant products included BENADRYL, ibuprofen, DECADRON, acetaminophen, PREMIXEL, lidocaine cream, and nystatin. On 21st March 2015, 2 days after receiving PRIORIX vs MMR II+HAVRIX+VARIVAX (+PREVNAR), the subject developed severe - grade 3 idiopathic thrombocytopenia. Serious criteria included hospitalization and medically significant. The subject was treated with OCTAGAM, WINRHO, FLEBOGAMMA, and prednisone. Priorix vs MMR II+HARVIX+VARIVAX+ (+PREVNAR) was continued with no change. The outcome of idiopathic thrombocytopenia was not recovered/not resolved. The investigator considered that there was a reasonable possibility that the idiopathic thrombocytopenia may have been caused by PRIORIX vs. MMR II+HARVIX+VARIVAX (+ PREVNAR).

Investigator text: Subject presented to emergency department 21Mar2015 with fever, upper respiratory infection and hives on arms and legs near injection sites. DECADRON, BENADRYL and ibuprofen given-rash resolved. Subject discharged home. Impression allergic reaction, URI, fever vaccination vs URI. Subject returned to emergency department 22Mar2015 with fever cough and rash-petechial scattered across some areas of coalescence at neck and legs. Vaccine sites with bruising-no cellulitis or abscess. Consult with pediatrics as petechia were concerning. CBC drawn-platelet count 6K/uL. Admitted for idiopathic thrombocytopenia, observation and potential transfusion. Admitting exam notes scattered pinpoint petechial rash with petechia convalescing into purpuric plaques on back of neck. Previous injection sites on arm and legs with indurated eccymoses, largest 2 cm. Numerous small bruises on arms and legs. Hematology consult sent. Assessment URI symptoms, fever and petechial rash and easy bruising. Most likely acute idiopathic thrombocytopenic. Event assessed temporally as related due to time and date of vaccine in relation to time and date of event. 08Apr2015-additional narrative-During hospitalization subject also diagnosed with bilateral otitis media and startd on amoxicillin. Subject discharged to home 24Mar2015 with diagnosis of thrombocytopenia, viral syndrome, otitis media and petechiae.

Subject readmitted to hospital 31Mar2015 for intravenous immune globulin therapy after laboratory results revealed platelets of 4K/uL.
