The reporter reported that her husband had a possible case of shingles after receiving both doses of Shingrix.   The reporter reported she believes he received the first Shingrix vaccine in July 2021 and the second Shingrix vaccine in January 2022, in unknown arm.  The reporter reported prior to receiving Shingrix, the patient received the Zostavax vaccine.  On 2nd Jan 2020, thepatient developed left hip pain and 8 days later the pain went down his left leg to a rash on his left foot, that was diagnosed as shingles by his HCP(health care professional).  The patient was given antivirals for 10 days, and the rash resolved, the nerve pain continued in his foot. The patient had a prior history of PMR (Polymyalgia Rheumatica) and this was not associated with the foot pain per his HCP. The reporter reported that after receiving the first dose of Shingrix, the patient received bivalent Covid vaccine booster in October 2022. The patient developed a severe headache and the HCP increased his prednisone (that he takes for his PMR) from 7.5mg daily to 40mg daily and then tapered back down because it caused a type of arthritis. The patient received his Flu vaccine on 9th Jan 2023 and no problem with the flu vaccine.  On 24th DEec 2022 the patient reported hip pain like the hip pain noted in 2020 (above).  This time the hip pain was on the right hip. Twenty five days later, on 18th Jan 2023 a rash develops on both the right and left feet.  The HCP did not test for shingles but does start Valacyclovir for 7 days.  The rash has resolved but patient still had the hip pain and nerve pain in his feet. The reporter did not consent to follow up. It was unknown if the reporter considered the shingles, headache, arthritis, rash and nerve pain to be related to COVID-19 BIVALENT BOOSTER.    Additional Supportive Information: This case was considered as suspected vaccination failure as details regarding laboratory test confirming shingles were unknown at the time of reporting.; Sender's Comments:  US-GSK-US2023AMR019792:same patient
