This is a spontaneous report from a contactable physician. A 48-year-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE) at the age of 48-year-old, dose 2 via an unspecified route of administration on 17Mar2021 (Lot Number: EN6198) as single dose for COVID-19 immunisation.  Medical history included Huntington's disease diagnosed in 1995, due to this her voice crackles a bit. The patient's concomitant medications were not reported. The patient was previously vaccinated with the first dose of BNT162B2 (lot number: EL9263) at the age of 48-year-old, for COVID-19 immunisation and she experienced 4 days of severe nausea, vomiting, couldn't get out of bed, couldn't eat, and diarrhea. The patient got her second dose on 17Mar2021 and had worsening of nausea, vomiting and fatigue on an unspecified date. The patient couldn't keep food down, can't sleep and keeps falling down, and he states "that really concerns me, she's going to knock her teeth out or bleed in her brain, that's not good". She's barely able to get around, doesn't leave unless she has a doctor's appointment. The problem is this, it's not the vaccine, it's the genetic modification this patient has Huntington's disease she was told it was safe, but don't think they took into consideration that it's a genetic modification and she has Huntington's which was also the genetic modification, don't know what to do at this point. He mentions that her nausea and dizziness was getting worse now that were a month out. She's falling down more than before. He wants to help her keep down food because she lost approximately 10% of her body weight. She's dizzy and weak, he states "she's wiped out, not sleeping". He also mentions that she's had hospitalizations. The reported was asking what do to next and if there was an on-staff physician for special cases. Patient reports going to the hospital 8 days after the second shot, she wasn't eating or sleeping. The second shot of Pfizer COVID vaccine was on 17Mar2021, patient began having severe vertigo, falling down, breathing hard, afraid she was going to knock her teeth out or break a bone, insomnia on an unspecified date. Patient reports she took a sip of water and threw up all over the side of the car today 20Apr2021. The Doctor states that this was not normal for her. Patient and reporter stated that the patient has lost between 10-15 lbs, about 10% of body weight. Reporter states that Ivermectin comes in custom lozenges and that it gets rid of inflammation so that it doesn't hurt the whole body. Ivermectin can make the GI upset. Caller states that it was not actually a vaccine that Pfizer was offering, reporter explains that Huntington Disease was when there was a repetitive code in the DNA, to the point it effects muscles and nerves and renders you. What Pfizer and Moderna was offering was a genetic modifier, mRNA was a genetic modifier, not a vaccine. In a Vaccine, they take a piece, make sure its dead, expose it to you and your body makes an antigen, that's a typical vaccine but this is not. Patient says Friday Saturday and Sunday she was stuck in the house. She cannot do anything. Reporter says the patient needs professional help. Her voice fluctuates so people take her seriously. (institute name), told the patient it would be ok to take the Pfizer COVID vaccine, but they didn't take into consideration is it was a genetic modifier. This was not a typical vaccine. Reporter states that he needs help escalating this please help with escalating this, needs help to know what to do for this patient because of the MRNA genetic modification. The mRNA may have affected the Huntingtons. The events resulted to hospitalization except for vertigo and breathing hard. The outcome of the events was unknown.; Sender's Comments: A possible contributory effect of suspect BNT162B2 on reported events cannot be excluded.  The impact of this report on the benefit/risk profile of the Pfizer product is evaluated as part of Pfizer procedures for safety evaluation, including the review and analysis of aggregate data for adverse events. Any safety concern identified as part of this review, as well as any appropriate action in response, will be promptly notified to regulatory authorities, Ethics Committees, and Investigators, as appropriate.
