    A SERIES OF EVENTS WAS REPORTED BY THE PATIENT'S MOTHER REGARDING ISSUES THE PATIENT HAS HAD WITH THEIR VNS. THE PATIENT'S MOTHER DID NOT NOTICE ANY VNS SIDE EFFECTS FOR THE REMAINDER OF THE DAY AFTER ACTIVATION. THE DAY AFTER, ON (B)(6) 2020, THE MOTHER NOTICED "COUGHING AND A LOT OF MUCOUS, BUT DID NOT THINK MUCH OF IT DUE TO HISTORY OF ALLERGIES, FREQUENT SINUS INFECTIONS, OR MAYBE JUST VIRAL." ON (B)(6) 2020, THE PATIENT WAS SEEN IN ED FOR FEVER AND INCREASE IN SECRETIONS. HE WAS GIVEN FLUIDS AND HIS FEVER IMPROVED, SO HE WAS DISCHARGED HOME. MOTHER ASKED "DR WHITE IN ED, IF HIS BODY COULD BE REJECTING VNS AND SHE AGREED IT COULD BE A POSSIBILITY." THE PATIENT RETURNED TO THE ED ON (B)(6) 2020 AFTER HE "WENT DOWNHILL AGGRESSIVELY." THE TC NOTED THAT "SATURATIONS" DID NOT COME UP BETWEEN HIS SEIZURES. HE WAS DIAGNOSED WITH "ASPIRATION PNEUMONIA." THE NEXT DAY, (B)(6) 2020, THE PHYSICIAN DEACTIVATED VNS WHILE IN THE ICU. PER HIS MOTHER "AFTER THEY DEACTIVATED IT, THE PATIENT IMPROVED." THE PATIENT WAS THEN DISCHARGED ON (B)(6). AFTER BEING DISCHARGED FROM ICU, "IT TOOK A LONG TIME TO GAIN HIS STRENGTH". IT WAS STATED THAT ONCE THE PATIENT COULD WALK AGAIN, HIS FOOT WAS JUST HANGING AND THE PHYSICAL THERAPIST SAID HIS FOOT DROP COULD BE RELATED TO STATUS." PER THE MOTHER, "HE IS BACK TO HIS NORMAL BASELINE." THIS INFORMATION WAS ORIGINALLY REPORTED IN MFR. REPORT # 1644487-2021-00319 AS THIS RELATED REPORT WAS NOT ORIGINALLY FOUND. INFORMATION WAS RECEIVED FROM THE PHYSICIAN HE DID NOT CONFIDENTLY ASSOCIATE VNS WITH ANY RESPIRATORY OR UPPER AIRWAY PROBLEMS IN A CAUSAL MECHANISM. NO OTHER RELEVANT INFORMATION HAS BEEN RECEIVED TO DATE.
