one of her sides was paralyzed/did not feel left side of body - face, arms and legs were numb; one of her sides was paralyzed/did not feel left side of body - face, arms and legs were numb; very bad rash/she had a rash everywhere/ rash on her whole body; she can't speak; She got a bad rash around the injection site; fainted 4 hours later/collapsed 5 times; Blood pressure went low/it was 60/90; This is a spontaneous report from two contactable consumers. A 29-year-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE, Batch/Lot number was not reported), via an unspecified route of administration, administered in left arm on 29Jul2021 (at the age of 29-year-old) as dose 2, single for COVID-19 immunization. Medical history included allergies to sulfa and penicillin. There were no concomitant medications. The reporter stated her landlord's daughter (patient) got her second shot of the Pfizer Covid-19 Vaccine and she fainted 4 hours later on 29Jul2021, she got a very bad rash, and had been in the hospital for 10 days now. She had to have a spinal tap, she couldn't speak and one of her sides was paralyzed. She said that the patient's mother told her that the patient was allergic penicillin and sulfa. She got a bad rash around the injection site in 2021. She said that the patient was going to be traveling, but got really sick from the second dose. The patient's mother later reported the patient took second dose of the Pfizer vaccine and she collapsed, clarifying she collapsed 5 times. They called ambulance and went to the hospital. She was still in the hospital and they were trying to remove her from the hospital because they were not doing anything for her. She said the patient worked for a doctor for 2 years. She did not know the name of patient's primary care provider or the doctor treating her now, clarifying there were so many doctors that she was seeing while in the hospital. The patient's mother said the patient had a rash on her whole body 4 hours after she took the 2nd dose of the vaccine on 29Jul2021. She went to the hospital because her blood pressure was too low. She said it was 60/90. The patient had allergies with other mediations, and the patient's mother said that maybe Pfizer's COVID vaccine had some product inside the vaccine that she was allergic to. She later stated she was allergic to Sulfa and Penicillin. She did not have a manufacturer and did not have a lot or expiration. She was a baby when it was discovered and said she would not drink that medication now because she knew it was not good for her. The patient was carried by ambulance and was admitted to hospital on 29Jul2021. Two days after this, she was discharged. They said she had nothing and she was ok and can walk now. The doctor said for her to follow up for neurologic and heart doctor. He was supposed to give shot for allergies while in the hospital and he did not, even though she had a rash everywhere. Now the patient was very bad.  She did not feel left side of body-face, arms and legs were numb. She cannot speak very well. She had no control of movements on left side.  She was hospitalized for all of this on 08Aug2021 and she had more rash that was back on her body. She remained hospitalized and the doctor never gave shot for allergies. She said the patient was very healthy. The patient's mother wanted to find out what can be done for her daughter and if there was anything in the vaccine that would be the same as Sulfa or Penicillin, since she was allergic to them. The outcome of the events "very bad rash/she had a rash everywhere/ rash on her whole body" and "one of her sides was paralyzed/did not feel left side of body - face, arms and legs were numb" was not recovered, of the other events was unknown.  The lot number for BNT162B2, was not provided and will be requested during follow up.
