no peripheral vision anymore; depth perception is completely gone; Dizzy spells; totally wiped out his sense of balance and he cannot walk unless he is being supported; totally wiped out his sense of balance and he cannot walk unless he is being supported; attacked his vision/ it has just about wiped everything out; This is a spontaneous report received from a contactable consumer (patient). A male patient of unspecified age received bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, lot number not reported), on 28Aug2021 as dose 2, single for COVID-19 immunization. The patient's medical history and concomitant medications were not reported. The patient previously received bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, lot number not reported) on 07Aug2021 as dose 1, single for COVID-19 immunization. Caller (patient) said that he needed to report an adverse reaction to the Pfizer COVID vaccine and how it had turned his world upside down. He went to (privacy) on 07Aug2021 and got his first dose, his wife went with him, and then on 28Aug2021 he returned and got his second dose and again his wife went with him at the same time. On 31Aug2021 (also reported as approximately 2 days after he had his 2nd dose) he started getting dizzy spells and it had progressed from there to where it had totally wiped out his sense of balance and he could not walk unless he was being supported and then it also attacked his vision and he had always had excellent peripheral vision and depth vision. At the time of this report (Oct2021) he had no sense of depth anymore with his vision and no peripheral vision anymore and it had just been made worse. He was unable to safely operate a motor vehicle because it had just about wiped everything out. He had to use a cane at the time of this report when he walked otherwise he loses his balance and he will go down. He didn't know if anyone had made more reports of this same thing but he had contacted his family doctor this morning and a couple weeks was as soon as he could get in to see them. They had told him that if this progresses further then his wife is to get him immediately to the emergency room at their nearest hospital. He just wanted to make someone aware of this side effect that he hadn't seen mentioned anywhere else. It had just spun his world completely upside down. He did go back to (as reported) because on his paperwork that they gave him it said to report it to Pfizer or through the place where his vaccine was administered at and the pharmacy couldn't tell him much of anything and couldn't tell him of any similar reactions. He just wanted to make someone and of this side effect that he had. Caller stated that he did not have such great service in his house. He said that he didn't have much time today for anything else, he just wanted to make someone aware of this new side effect that maybe other people are experiencing as well. At the time of this report (Oct2021) his world was upside down and his depth perception was completely gone. He could reach for something, like a cup on the table, and when he reached for the cup, he might end up grabbing something else that was a foot and a half away from where he was reaching. His sense of balance was what he was worried the most with. The number of days that he had been since this started he really hadn't shown any signs of improving. Maybe he will know more when he had his visit with his doctor and see if they want to check for anything else. The outcome of the events was not resolved.  No follow-up attempts are possible; information about lot/batch number cannot be obtained. No further information is expected.
