three weeks anaphylactic response; cause of my autism and my ADHD skyrocketing/I had them all managed and now they are controlling me; protein allergy; cause of my autism and my ADHD skyrocketing/I had them all managed and now they are controlling me; This is a spontaneous report received from a contactable reporter (Consumer or other non HCP). The reporter is the patient.  A 25-year-old female patient received BNT162b2 (BNT162B2), on 26Jul2021 as dose 1, single (Lot number: EW0164) and on 17Aug2021 as dose 2, single (Lot number: FC2181) at the age of 25 years, in left arm for covid-19 immunisation. The patient's relevant medical history included: "I had Covid twice" (unspecified if ongoing), notes: I had Covid twice and then I got vaccinated. But I have not had Covid since I was vaccinated though. The patient's concomitant medications were not reported. The following information was reported: ANAPHYLACTIC REACTION (hospitalization, medically significant), outcome "unknown", described as "three weeks anaphylactic response"; AUTISM SPECTRUM DISORDER (hospitalization, medically significant), ATTENTION DEFICIT HYPERACTIVITY DISORDER (hospitalization, medically significant), outcome "unknown" and all described as "cause of my autism and my ADHD skyrocketing/I had them all managed and now they are controlling me"; FOOD ALLERGY (hospitalization, medically significant), outcome "unknown", described as "protein allergy". Clinical course: The patient was wondering if there have been any reports of the Pfizer shot exasperating options on her ADHD because that's what's going on with her and threw her into anaphylaxis twice. Her family got so worried, so she called to see if this is a known thing because she is safe and okay. She would just rather let it be known so that other people who got similarities with her know what to watch out for. It was reported that after the Covid-19 vaccine, she got her second shot and then the first one gave her night sweats and just over sensitivity and then she was about to get the second one which she did indeed received and gave her almost three weeks anaphylactic response and she almost died in the hospital and now they are finding it the cause of her protein allergy like to the point where she needs an Epipen (treatment) and they are finding it to be the cause of her autism and her ADHD skyrocketing. She had them all managed and now they are controlling her. So, she is just unsure and want to report and make sure Pfizer knows what is going on. She just want to make sure that people are aware so that they can get the help they need. She got her shot last year then the second shot was 2 days after she turned. Her final shot was 17Aug2021 having the health issues last year and then everything else. She had to start about four different new medications due to this. 3 of them are allergy meds and one of them was switch on testosterone and right now, she was started on 3 different allergy medications. They started an Epipen on reserve and now on Prednisone. She have got Prednisone 10mg tablets for the next 5 days to try and get her allergy symptoms down, 180 mg tablet of Allegra daily but they might have to change it to twice a day. She has Singulair 10mg tablet every night, Epipens as needed, Epinephrine 0.3mg injections as needed. She has an Albuterol inhaler and Flovent inhaler for treatment. They are trying treatment, injecting in her allergy slowly and trying to get her allergy down that they never would have had to do prior to this. She received the vaccine after the pandemic. She was not hospitalized for Covid based on literally 0.5 temperature. She had Covid twice and then got vaccinated but she had not had Covid since she was vaccinated though. The patient underwent the following laboratory tests and procedures: Body temperature: 0.5 temperature. Therapeutic measures were taken as a result of anaphylactic reaction, autism spectrum disorder, food allergy, attention deficit hyperactivity disorder.  Follow-Up (02Nov2022): Follow-up attempts are completed. No further information is expected.
