Additional Information: GSK Receipt Date: 11-MAY-2023 The patient received both the doses of Shingrix vaccine in 2019. The patient did not have the exact dates of the shots but did provide the pharmacy contact information who should have the dates (and lot numbers) on file. A couple of months ago patient came down with a severe case of shingles in 2023 which has not fully resolved. Patient reported that she started having neuralgia pain in right hip down into my groin area. The patient thought she had a hip problem or pulled a muscle because she was active.  This started several months before the blisters broke out. When the blisters broke out she had no warning. She was washing her back and she almost passed out because her back, side, and hip were covered with blisters.  The pain became unbearable, then it was in the right TFL (Tensor Fasciae Latae) area and across her lumbar region, right lower quadrant of abdomen felt like she was having appendicitis. Pain was deep in right groin and radiated into right knee.  Patient husband took her to the emergency room because her was doubled over in pain and could not walk, could hardly breathe.  As soon as they saw the blisters they diagnosed patient with shingles.  Patient did two rounds of acyclovir and they prescribed gabapentin for a month.  The Physician's Assistant told me to cancel everything for the next 3 to 6 weeks and he was correct. It was debilitating.  Patient could not do (normal activities) for almost 2 months. But things were better now the patient was back to teaching, she could mow the lawn, could hike with the dogs. The patient still on the gabapentin.  The patient was much better but still had a shadow of the neuralgia pain and her right TFL was still firing. The blisters cleared up.  They dried up and they just have marks were they were. She also said that during the shingles outbreak she had chills, was under piles of blankets, could not get warm. The shingles outbreak caused her to have chills, nausea, brain fog, and total lethargy.  The reporter asked her if these events had resolved. She said that she still does get chills once in a while.  She gets brain fog and fatigue occasionally, but she could function now. The reporter consented to follow up. This case was considered as suspected vaccination failure since the details regarding laboratory confirmation of shingles was unknown at the time of reporting.
