A 19-year-old male patient received bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE) intramuscular (IM), administered in right deltoid on 25Jun2021 (Batch/Lot Number: EW0196; Expiration Date: 01Sep2021), at the age of 19 years old, as dose 2, single for covid-19 immunisation in a clinic. Medical history was reported as follows. He has heart aneurysms and was diagnosed with Kawasaki at 4 years old. They found out 7-10 days later after he had the heart aneurysms. When he was diagnosed with that, there were so many questions back then about how they develop it. He has diagnosed allergies, compromised immune status, respiratory illness, genetic/chromosomal abnormalities, endocrine abnormalities (including diabetes) and obesity. He is a little overweight at the time of report, but not as a child. He started gaining weight when the COVID thing started and was at home for school versus walking around at school.  This was prior to vaccination. He had to have tissues with him all the time for seasonal allergies started as a kid. He was previously diagnosed with autism and cognitive dysfunction and was high functioning and worked 3 hours a day and was also in college. Family medical history relevant to AEs include diabetes, and high blood pressure. Concomitant medications were not reported. No prior vaccinations within 4 weeks.  The patient previously received dose 1 of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE) on 04Jun2021 (lot EW0172, expiration 01Aug2021) IM administered in right deltoid for COVID-19 immunisation. The reporter stated things started happening after the vaccine. A week or two later, on unspecified dated in 2021, he started having nightmares. He never had them before. It went week after week from nightmares to seeing things in the dark to hearing voices like 4-5 weeks later. He was seeing things at home like shadows. From that, it went to things talking to him or things touching his skin. He felt things crawling on him and pulling at him. Started at night and lasted all night and day. He was fanning himself and pulling at himself.  He felt things crawling on him and hearing voices 3-4 days ago. He was hearing voice at night at first and then it was all the time. She does not know anything about psychotic episodes. When she came home, he was talking to himself. She thinks the vaccine played a part.  She is concerned about parents with children with autism and knows that people with schizophrenia shows that it occurs between 18-25 years old, but it was different after the vaccine. She told the doctor 2 weeks after he had the nightmares. She was doing natural things at home to see if it would help. She said no eating after 7pm and no playing video games. No scary movies, and then he confessed to her about 3 weeks after they did not go away, that he was seeing them in the house. He was admitted to a mental hospital 4 days ago. He has been talking to himself. He still says he sees these things. She honestly believes he could read and everything opposite of what they said he could do. He wanted to learn to drive.  Four days ago, the nightmares lead up to seeing things and talking to himself.  When she got off work on 13Oct2021 at 6:00 am, she came home and was talking to him and he turned around and he was talking to her as a different person. He said he was another person. She took him to the Emergency Room after that.  He stayed in the ER for 18 hours and was not admitted to the mental hospital until 14Oct2021. When she told the doctor about the nightmares, she prescribed something for them, clonazepam. They were in a pharmacy vial with no lot or expiration. He was taking 0.5mg once nightly.  He also started taking melatonin, over the counter gummies.   He was not being honest about the nightmares.  He told her that he was still having them and went from having normal conversations to now that he is not himself.  She still is going to see him every night. They were in the emergency room for 18 hours, and because he could not sign consent by local health facilities by himself, they would not take him. They received medication from ER doctor that night because they could not get into medical facility. She called administrator at mental health facility and they apologized and got him in that night at 6:30 pm. He was admitted on 14Oct2021. Because they would not take him into the mental health facility, she did not have guardianship at the time. She took him to the physician on 14Oct2021, and the physician helped with paperwork for guardianship. She said it was a longer process though. He was prescribed 5Htp and they ended up not needing it and ended up getting him on psychotic medications. She questions about any vaccines at all. She does not know if he is one of those people that reacts and gets autism. People start talking and she hears things.  This one was a little more obvious because he was not having these issues before. The patient has not recovered from the events.
