After leaving the facility ended up passing out in the car; caller's arm was bleeding; feeling kind of dizzy; the administering person didn't check the syringe before administering; This is a spontaneous report from a contactable consumer (patient). A 28-year-old female patient received the second dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE) via an unspecified route of administration, administered in left arm on 07May2021 (Between 1830 and 1900) (Lot Number: EW0182) as single dose for COVID-19 immunization. Medical history included Covid Virus in Dec2020 (had the Covid Virus but received the vaccines to prevent if it were to happen again). The patient's concomitant medications were not reported. The patient previously received the first dose of BNT162B2 (lot number: EW0161) on 16Apr2021 (Between 1830 and 1900) in left arm for COVID-19 immunization. Patient went to Pharmacy to receive her second dose Pfizer Covid Vaccine. Thought there was a mistake coming from the person who gave the vaccine. After the administering person supposedly gave the patient her second dose Pfizer Covid Vaccine, the administering person started making some faces like she was concerned. The patient asked three times, what was going on and the administering person would not tell the patient. The patient asked to please tell her what was going on, the administering person's face was very concerned. The administering person finally told the patient, she wasn't sure, it just felt weird when injecting the second dose Pfizer Covid Vaccine. Patient asked the administering person what she meant by it felt weird and the administering person stated she thought the syringe was empty. The patient stated the administering person was scared. The patient looked at her arm and it was bleeding quite a bit. Patient thought the injection was weird, usually injections in muscles can hurt but this just felt different. Patient stated it felt like the injecting needle was dull, like it had already been used. The administering person thought the syringe was empty so the patient thought was that someone else's syringe that had already been used and the administering person didn't pay attention. Patient is not sure if she received the second dose Pfizer Covid Vaccine. The administering person got up and was about to walk out the door and saw the patient's arm was bleeding. The person said she would clean it up and she did. The administering person stepped outside and asked whoever pulled the vaccine to see if the syringe had the vaccine in it prior to administering to the patient. The patient stated the administering person didn't check the syringe before administering the second dose Pfizer Covid Vaccine to the patient. Otherwise, the administering person would have known if the syringe was full or not. The administering person came back in after she had stepped out for two or three minutes. The administering person told the patient she was good and did receive the second dose Pfizer Covid Vaccine. Patient asked how did the person know, if the administering person had said the syringe felt empty. The administering person said no, the patient did receive the second dose Pfizer Covid Vaccine. The administering person sat next to the patient and the patient asked are you sure, administering person said yes.  At this time, the administering person had a 3cc syringe in her had with something in it and she threw this syringe away. Patient asked the administering person again if she was certain patient received second dose Pfizer Covid vaccine and the administering person said yes. The administering person was still playing around with the syringe the patient supposedly received the second dose Pfizer Covid Vaccine with, like the administering person was doubting herself. Patient was concerned now, if the administering person did in fact use a syringe that was previously used by someone else. Patient didn't know if the person who previously utilized the syringe had something or not. After leaving facility the patient ended up passing out in the car. Some random person in the parking lot got someone from inside the facility. The facility cashier came to see the patient. The patient stated no Pharmacist came outside, just the cashier. After 20 minutes or so, patient 's parents ended up showing up to make sure the patient was okay. The patient got home and a Pharmacist called and basically said how the patient probably passed out because she hadn't eaten. The patient stated she had eaten just not within an hour or two prior to receiving the second dose Pfizer Covid Vaccine. The patient stated the pharmacist was giving a lot of excuses and saying that the patient passed out probably because she didn't eat. Patient asked the pharmacist why no one came out to make sure the patient was fine. The pharmacist said they were changing persons in rotation. Patient stated this hasn't happened before. This may have occurred due to stress and patient getting scared due to the administering persons concern and facial expression and what the administering person said to the patient. The patient got really scared. The patient didn't know if that had anything to do with passing out. Patient didn't think the administering person gave the patient the second dose Pfizer Covid Vaccine at all. As the patient was leaving the facility, patient was getting closer to the car and started feeling kind of dizzy. Patient opened the car door and ended up passing out. Patient stated this occurred this one time, patient was recovered completely. Right before patient was almost passed out entirely, patient had gone to get somebody in the parking lot and asked the person to get someone from inside. Patient asked the Pharmacist if the person who administered the second dose Pfizer Covid Vaccine to the patient, was the person who drew up the patient's vaccination into the syringe. The pharmacist said yes, (name) drew up the vaccine into the patient's syringe. Patient stated the Pharmacist was lying to the patient, (name) told the patient she was not the person who drew up the vaccine into the syringe and went to check to see who had drawn up the vaccine into the syringe after the patient received the second dose Pfizer Covid Vaccine. The Pharmacist changed the subject entirely. The patient underwent lab tests and procedures which included Covid Virus: present in Dec2020. Outcome of the event passed out was recovered on 07May2021, of the other events was recovered on an unspecified date.
