Blood work done every 6 months, cholesterol around like 179 blood pressure good. she had no issues. A1C was 5.9, but she was not on any medication for pre-diabetic diagnosis. Onset about 1.5 years ago, think first A1C test was year and half a go, and she has had 3 A1C tests so 1.5 years ago was right. Everything was well controlled. Investigation assessment stated as no. This consumer is the patient who reported having mild side effects after being administered the first dose of Pfizer Covid-19 Vaccine which included weird taste in her mouth; lightheaded; little bit dizzy; irritable; face itching; heaviness in her chest. These events did not require her to go to the emergency room or hospitalization or anything. Caller did not want to provide any relative information for her providers. Within she would say maybe 2 minutes of receiving the injection of Pfizer Covid-19 Vaccine she could taste this weird taste in her mouth; like some meds or injections after taking them you can taste it. That did not really bother her. Within 30 minutes after she had the injection of Pfizer Covid-19 Vaccine she just started feeling lightheaded and a little bit dizzy, but that is normal, expected, that did not bother her. Starting later that day she became very irritable, and her face itching started really bad, not just in one place, all over; and she also started having like a heaviness in her chest. The heaviness in her chest lasted for next 4 days just an on and off. That is when she decided to call the doctor. She never had any swelling or trouble breathing, just the heaviness in the chest and face itching. Occasionally she still has face itching and irritability. The weird taste in her mouth stopped, it did not last that long, she is going to say it did not last over an hour. The heaviness in her chest has not come back, after the 4th day it seems to be gone. The CDC vaccine record card does not show strength or volume of dose she was administered; the only thing that might be relevant is that on the paper that the pharmacy gave her for the Pfizer Covid-19 Vaccine it shows quantity 0.3 days 3. She does not know what that means but wanted to provide it in case it was relevant. Regarding treatment for events and any relevant testing/investigations caller verified that there has been none. She called 2 different doctors she had; the first one consulted with 2 other doctors there and they all agreed that it sounded like she was having an allergic reaction, and advised her not to take anything else, no additional doses of Pfizer Covid-19 Vaccine. She called another one of her doctors who she figured was more up on the vaccines and stuff that she sees occasionally, and he said definitely do not take another dose of Pfizer Covid-19 Vaccine because he was afraid, she would have another allergic reaction that was worse than this one. They both advised her not to get any additional doses (second dose) of Pfizer Covid-19 Vaccine in response to these events which they felt could be a mild allergic reaction to the Pfizer Covid-19 Vaccine. One of her doctors said maybe if they change the vaccine, she might be able to get another dose but that would not be for at least 6 months. anatomical location of administration of pfizer vaccine considered as suspect was left upper arm.
