This case involves an unknown age male patient who experienced itching kept him up at night to the point where he would have to take hot showers to try and quell the itch, about 7-8 days after the shot he broke out in massive hives this went on for several weeks and he suffered terribly after receiving Influenza Quadrival A-B High Dose Hv Vaccine [Fluzone High-Dose Quadrivalent].  The patient's past medical history, medical treatment(s), vaccination(s) and family history were not provided. At the time of the event, the patient had ongoing Shellfish allergy and Heart disorder.   On 18-Dec-2023, the patient received a unknown dose of suspect Influenza Quadrival A-B High Dose Hv Vaccine (formulation, strength, expiry date, lot number not reported) via unknown route in unknown administration site for Prophylactic vaccination (Immunization). The information on batch number was requested.  On an unknown date the patient had itching kept him up at night to the point where he would have to take hot showers to try and quell the itch (sleep disorder) , (pruritus) and about 7-8 days after the shot he broke out in massive hives this went on for several weeks and he suffered terribly (urticaria) (unknown latency) following the administration of Influenza Quadrival A-B High Dose Hv Vaccine.  Reportedly "my husband received a flu shot at. His primary care physician recommended he get the shot and the pharmacist told us that this is specifically for seniors when we asked what was in the shot. We purchased over the counter anti itch medications like Benedryl but they didnot help that much and the hives kept breaking out so his doctor had to prescribe a round of steroids for 5 days. The steroids seemed to resolve the issue for a couple of days until he had a shrimp salad. That night he broke out in hives again. It appears he now has an allergy to shellfish which he never had before. He was up several times during the night putting hot towels and cream on to relieve the itch and his doctor prescribed another round of steroids. My husband is a senior with a heart condition. Getting up at all hours of the night with an unrelenting itch and hives breaking out all over his skin is severely impacting his ability to get proper rest. We need some answers what was in the shot and why is there no warning given to the patient of possible side effects or allergic reactions. Below are pictures of the product that was administered to him. It is not normal or acceptable for someone to have this kind of inflammatory response to a seasonal flu shot and he cannot continue getting rounds of steroids."  Action taken was not applicable.  The patient was treated with Diphenhydramine Hydrochloride (Benadryl [Diphenhydramine Hydrochloride]) for Itching and prescribe a round of steroids for 5 days.  At time of reporting, the outcome was Unknown for all the events.
