brain had swollen on both sides completely; Everyday he has a new infection. The last one was enterovirus; Everyday he has a new infection; antibiotic resistant infections/antibiotic resistance; This is a spontaneous report received from a non-contactable reporter(s) (Consumer or other non HCP), Program ID: (RA).  A 74-year-old male patient received BNT162b2, BNT162b2 omi ba.4-5 (BNT162B2, BNT162B2 OMI BA.4-5), as dose number unknown, single (Batch/Lot number: unknown) for covid-19 immunisation. The patient had no relevant medical history. There were no concomitant medications. The following information was reported: BRAIN OEDEMA (hospitalization, medically significant, life threatening), outcome "unknown", described as "brain had swollen on both sides completely"; ENTEROVIRUS INFECTION (hospitalization, medically significant), outcome "unknown", described as "Everyday he has a new infection. The last one was enterovirus"; INFECTION (hospitalization, medically significant), outcome "unknown", described as "Everyday he has a new infection"; PATHOGEN RESISTANCE (hospitalization, medically significant), outcome "unknown", described as "antibiotic resistant infections/antibiotic resistance". The events "brain had swollen on both sides completely", "everyday he has a new infection. the last one was enterovirus", "everyday he has a new infection" and "antibiotic resistant infections/antibiotic resistance" required physician office visit. The patient underwent the following laboratory tests and procedures: Scan: Brain swollen on both sides, notes: The scan showed his brain had swollen on both sides completely. Clinical course: The patient was in the hospital right now fighting for his life. The caller had declined contact details. Reporter's brother has never had issues. He didn't take medications. One day, after the vaccine, she went to his house and he was completely out of it. He couldn't figure out what clothes put on. She got him to the hospital, and they said he had a UTI, but it wasn't a UTI. The next day he was even worse. They got him back and did a scan. The scan showed his brain had swollen on both sides completely. Now every day it was something else now. They say he had antibiotic resistant infections. Everyday he had a new infection. The last one was enterovirus. She has watched this man go from cutting grass and healthy to a shell of a person. This hasn't just happened to him. She saw an online video that the vaccine contains sv40 which is a cancer-causing virus, and a DNA virus which causes antibiotic resistance. Now Reporter's brother was a vegetable. Caller stated, how was this possible when they stopped the swine flu after 25 people. She just wants more information on what can be done. This man has antibiotic resistance. The doctor's are all stumped with no idea what to do.  No follow-up attempts are possible; information about lot/batch number cannot be obtained. No further information is expected.; Sender's Comments: Linked Report(s) : US-PFIZER INC-202300250415 same reporter/product, different patient/AE;US-PFIZER INC-202300250416 same reporter/product, different patient/AE;US-PFIZER INC-202300250417 same reporter/product, different patient/AE;US-PFIZER INC-202300250418 same reporter/product, different patient/AE;US-PFIZER INC-202300250420 same reporter/product, different patient/AE;
