CHEST PAIN; ACHES; STRANGE NUMB SPACES IN BRAIN; CONFIRMED CLINICAL VACCINE FAILURE; CONFIRMED COVID-19 INFECTION; DIFFICULTY FALLING ASLEEP; TINNITUS; RACING HEART; NUMBNESS TO LEFT AND RIGHT ARMS (MOSTLY LEFT) FROM ELBOW TO PINKY AND INCLUDED FORE FINGER; TINGLING TO LEFT AND RIGHT ARMS (MOSTLY LEFT) FROM ELBOW TO PINKY AND INCLUDED FORE FINGER; This spontaneous report received from a patient concerned a male of unspecified age and ethnic origin. The patient's height, and weight were not reported. The patient's concurrent conditions included: ear infection (The patient had an ear infection in both ears one month before he received his COVID vaccine). The patient received covid-19 vaccine ad26.cov2.s (suspension for injection, route of admin not reported, batch number: 1822811 expiry: UNKNOWN) 1 in total, dose was not reported, administered on 15-OCT-2021 to left arm for covid-19 prophylaxis. No concomitant medications were reported.  On 16-OCT-2021, not the day of vaccine, but the day after he woke up at night with a racing heart, beats about 100 beat per min when he checked that faded quickly over days. On 17-OCT-2021, two nights after he received the vaccine he experienced ringing in his ears, high pitched noise, a "wooshing" noise in his ear, normally when he laid on bed as going to sleep or first waking up. That wooshing noise developed into tinnitus in both ears, but more in left ear. Over days or weeks, it became more serious. The patient hoped it would go away, but it had not, he reported that, it was really a bothersome when that happened and it prevented him to fall asleep. Talked to a doctor about it in January. Referred to ear doctor and had testing done but did not have any hearing loss. Audiologist prescribed him hearing aids (Oticon) which allows to create different frequencies and patterns like white noise and helps to prevent tinnitus. Doctor tried antibiotics and steroids, but it did not help. The patient tried not drinking coffee and alcohol and listening to noises on his phone per audiologist recommendation. That lead him to audiologist that gave him the hearing aid. Patient was still experiencing tinnitus not that bad, but sometimes unbearable which affected his ability to do things. After he got vaccination (OCT-2021) he started developing numbness to tingling and left and right arms (mostly left) from elbow to pinky and included fore finger, experienced tingling and numbness that had pretty much stopped almost gone now but still comes here and there (still having that numbness sometimes). On 10-DEC-2021, two months after getting vaccine, the patient tested positive and did not lose taste (Laboratory data included: COVID-19 virus test Tested positive twice with home test). He was extremely tired, loss of smell, flue feeling, and sneezing, the patient had sinus issues, but did not have lung issues and he was unbelievably tired (coded as confirmed covid-19 infection which led to confirmed clinical vaccination failure). The patient reported that the racing heart had stopped. He stopped exercising for a while. The patient had chest pain and aches which he described it as felt mostly like heartburn. On an unspecified date in 2022, the patient experienced strange numb spaces in brain that would last for a couple seconds to a minute and then go away and lasted two months and went away.  The action taken with covid-19 vaccine ad26.cov2.s was not applicable. The patient recovered from racing heart, and strange numb spaces in brain, had not recovered from tinnitus, tingling to left and right arms (mostly left) from elbow to pinky and included fore finger, difficulty falling asleep, and numbness to left and right arms (mostly left) from elbow to pinky and included fore finger, and the outcome of chest pain, aches, confirmed covid-19 infection and confirmed clinical vaccine failure was not reported. This report was serious (Other Medically Important Condition). This report was associated with product quality complaint: 90000259506. This case, from the same reporter is linked to 20221136215.; Sender's Comments: V0: 20221135750- confirmed clinical vaccine failure. The event has a compatible/suggestive temporal relationship, is unlabeled, and has unknown scientific plausibility. There are other factors more likely to be associated with the event. Specifically: SPECIAL SITUATIONS. Therefore, this event is considered inconsistent with vaccine administration.
