The patient's concurrent conditions included attention deficit disorder (ADD), and kidney stone. The patient's historical procedure included cholecystectomy laparoscopic in May-2015, and lithotripsy on an unspecified date. The patient's concomitant medications included cetirizine for congestion, Flomax (tamsulosin hydrochloride), Mononessa (ethinylestradiol, norgestimate), Naprosyn (naproxen), and Vyvanse (lisdexamfetamine mesilate), all used for unreported indications.

It was reported that on 20-Sep-2022, the patient was vaccinated with Fluad Quadrivalent (influenza vaccine inact sag 4v; route of administration: injection (reported as 'SYR'); dose, anatomical location, and indication: not reported). The batch number reported was 942385. The reported batch number was identified by Seqirus to be linked to suspect product Flucelvax Quadrivalent (influenza vaccine inact sag 4v) instead of reported suspect product Fluad Quadrivalent. Based on the reported batch number, the suspect product was changed to Flucelvax Quadrivalent.  On 07-Dec-2022, two months and 17 days after receiving Flucelvax Quadrivalent, the patient visited emergency department (ED) and tested positive for influenza A (explicitly coded as 'Vaccination failure').     On 10-Dec-2022, the patient visited ED again with complains of headache from that morning that was not relieved by Aleve (naproxen sodium) and Excedrin (acetylsalicylic acid, caffeine, paracetamol). Patient was Influenza A positive and was beginning to feel better of majority of flu symptoms. The patient had nausea without vomiting. The patient denied numbness/tingling/weakness/visual changes.

Physical Exam/Objective vitals and measurements last 24 hours: Vital signs: temperature: 37.1  degrees Celsius; heart rate: 84 beats per minute (bpm); respiratory rate: 18 breaths (br)/min; blood pressure (BP): 120/71 mmHg; oxygen saturation (SpO2): 99 % on room air; height: 172.7 cm; weight: 75.5 kg (ideal body weight: 63.88 kg); General: alert, no acute distress; Head: no trauma, normocephalic; Neck: trachea midline, no adenopathy, no tenderness; Chest wall: no deformity; Extremities: no deformity, no trauma. After assessment for influenza and headache, the patient was discharged with follow up plan and strict ED return instructions. All additional queries were answered. The patient was in stable condition. The patient was instructed to follow up with primary care provider within three to five days. The patient was given ketorolac 60 mg, intramuscularly, and promethazine 25 mg, orally.   At the time of initial reporting the patient was recovering from the event of 'Influenza A virus infection' as she was beginning to feel better of majority of flu symptoms. The patient had not recovered from the event of headache.   The reporter did not provide causality assessment.   The events of 'Influenza A virus infection' and 'Vaccination failure' were considered to be medically significant by a Physician within Seqirus' Pharmacovigilance and Risk Management Department.  Company comment: A 26-year-old female patient was vaccinated with the suspect product Flucelvax Quadrivalent. Two months and 17 days after vaccination the patient visited emergency department (ED) and tested positive for influenza A (explicitly coded as 'Vaccination failure'). Three days later the patient experienced headache for which she visited ED. There were no significant findings detected following diagnostic workup. Based on plausible temporal relationship causality for influenza, vaccination failure and headache is assessed as possibly related.; Sender's Comments: A 26-year-old female patient was vaccinated with the suspect product Flucelvax Quadrivalent.
