The patient stated prior to receiving Shingrix complete vaccine series she was diagnosed with a case of shingles on her spine (date not disclosed). The patient stated she presented to her local emergency department for flank pain and the pain was located on the front and back of her waist. She did not have a rash only intense pain.   It had been over 2 weeks of stabbing pain without a rash. The patient stated the emergency department ruled out an issue with her spleen or her pancreas.   Patient stated blood work was done, and she was tested positive for mononucleosis. However, the consumer stated she was told by the emergency department physician the flank pain she was experiencing might be an internal case of shingles.   The consumer stated she was now in her 3rd week experiencing this flank pain that could not be explained after an ultrasound or a CT of the abdomen. The only explanation was shingles pain without the rash. The consumer stated the emergency room physician did not prescribe an antiviral medication. The consumer stated GlaxoSmithKline could contact the pharmacy that administered the vaccine to obtain that information. This case was considered as suspected vaccination failure as details regarding laboratory confirmation regarding zoster sine herpete were unknown at the time of reporting. No further information was provided or obtained.; Sender's Comments: Vaccination failure is a listed event which, due to the following criteria (insufficient information provided about completion of primary vaccination schedule and regarding laboratory confirmation of shingles) is considered unrelated to GSK vaccine Shingrix (Dose 1 & 2).
