problems breathing; allergic reaction; rash on the left ankle; hypersensitive on certain frequencies was reported as worsened; hypersensitive on certain frequencies was reported as worsened; his vision since the shots was compromised/vision in the lower section had shrunk even more/gotten worse; he moved things, but couldn't remember where he moved them; residual neuropathy in feet was reported as worsened; This is a spontaneous report from a contactable consumer (patient himself). A 74-year-old male patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for injection), via an unspecified route of administration, administered in the right upper arm on 04Mar2021 at 11:00 (Batch/Lot Number: EN6199) as the 2nd dose, single for COVID-19 immunization. The vaccine was administered at the military facility. He previously received the 1st dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE; batch/lot number: EN9581) on 11Feb2021 at 2-3 pm (at the age of 74 years old) in the right upper arm and experienced a bout of diarrhea, but he took loperamide (IMODIUM) and it went away; he expected the first shot and last only about a day. Relevant medical history included ongoing legally blind, wherein his central vision was screwed up and this was something going on before the shots and with his peripheral vision, there were areas he could see clearly, and also had eye pain; his hearing was hypersensitive on certain frequencies, which was ongoing; and residual neuropathy in feet; all from an unknown date prior the vaccine. The patient had no concomitant medications. The patient previously took clonazepam (KLONOPIN) from an unspecified date in 2009; further reported that the patient had no information on this medication other than it was Klonopin that caused him to stop breathing and put in coma in 2009 and that he was given intravenous (IV) antibiotics, because he had 3 major infections and this was when the issue with his vision started. The patient previously received and stopped getting the flu shot years prior reporting when he got sick for 6 weeks. The patient had no prior vaccinations (within 4 weeks) other than the first dose. The patient had no family medical history relevant to the adverse events (AEs). The patient reported that he got the second shot of the Pfizer COVID-19 vaccine and within 5 minutes, he had a severe reaction. He was in an observation area at the facility and less than 5 minutes after getting the shot, he had problems breathing on 04Mar2021, it was painful to breath; however, it was further reported that "painful" was not the word for the problems breathing. The triage team gave him shots and he went to the emergency room (ER) and ended up spending the night in the hospital. It was further reported that they gave him an epinephrine (EpiPen) and some other shot in the left arm and diphenhydramine (BENADRYL) in the right arm and put on oxygen on him. He was admitted to the hospital and released the next day. He was given the option to leave the next day and so he did. The doctor explained, they were concerned it was cardiac related, but did blood work and told them he was fine on an unspecified date in 2021. The doctor also told him they saw a rash on the left ankle on 04Mar2021 and therefore knew it was an allergic reaction. The rash on ankle was barely visible the next day, it had resolved though, but was not sure of the exact date. He couldn't have seen it anyway. There had also been other issues since then. He remarked that he moved things, but couldn't remember where he moved them on an unspecified date in 2021. On an unspecified date in Mar2021, the hypersensitive on certain frequencies was reported as worsened. Regarding the patient's hearing, he explained that while in church, they were playing music and it was pure pain. He went to the clinic and saw an otolaryngologist, who told him that his hearing was hypersensitive on certain frequencies, not all though. He stated he had this before, but never with music at the church or like this. He was in the car and a car beside him with heavy base playing was giving him issues; the same kind of the pain, but on the opposite end with base. This was something new and not like he had before. It was ongoing and he had not gone back to church, so as not to experience this again. This started within a week or 2 after the second shot. Since the shots on an unspecified date in Mar2021, his vision was compromised. There were upper and lower areas, "sweet spots," he could see. With his last check up, the vision in the lower section had shrunk even more; where he could see from about the 3:30 to 8:30 area before, currently it was from 5:00 to 7:00. He explained this was like on a clock. Also he was able to see the big E at the top of a vision chart, but in Mar2021 after the second shot, he noticed within days, he could no longer see the large E. He had a regularly schedule appointment a couple weeks after the second shot and this was noticed. It had gotten worse. Additionally, he would stand in front of the eye chart and as part of the eye exam, they would hold out fingers to see if he could see them. Last year at 6 feet (ft), he could see them, but currently, he couldn't see them until 2 ft away. If he was in bright light, he had severe eye pain, to the point of crying. He had to leave and get out of that situation, it was so bad. Even going outside with a hat and sunglass without looking at bright light, it still impacted him. The lighting in his bathroom bothered him; he had to have the blinds closed and was home bound. His closet was the only way to get relief. This was all new since the Covid shot. On an unspecified date in 2021, the residual neuropathy in feet was reported as worsened. He had this previously, but currently had hypersensitive in his feet in those areas. The patient found some essential oils that help so he could get to sleep and keep it from itching in his feet. The patient was deducting that for whatever reason, it was impacting nerve areas that had issues previously. It was causing them to get worse. He could only find this commonality; the optic, auditory, and residual neuropathy, the shot was aggravating these things that he already had problems with previously. It was added that he had also noticed his eyes had a throbbing pain, like a feeling of wanting to explode. He has had this in the past, but not too often and currently, it was daily and it was getting worse. It started about 3 weeks after, but it didn't happen often at first. Currently, it was almost daily. The doctor told him that there was not a way this could happen, there was no evidence this could happen. There had been no treatment, nothing had been done. He said with his DNA, if something could go wrong even just 1% then it would happen to him. The AE "problems breathing" did require an ER visit. The patient was hospitalized for the event problems breathing from 04Mar2021 to 05Mar2021. The patient underwent further lab tests and procedures, which included hearing test with unknown results on an unspecified date. Therapeutic measures were taken as a result of problems breathing, allergic reaction, and rash on the left ankle. The patient recovered from the event "problems breathing" on 04Mar2021; he recovered from the events "allergic reaction and rash on the left ankle" on an unspecified date in 2021; he was not recovered from the events "residual neuropathy in feet was reported as worsened, hypersensitive on certain frequencies was reported as worsened, and his vision since the shots was compromised/vision in the lower section had shrunk even more/gotten worse," while the outcome of the other event was unknown.
