Additional information: Reporter stated that she was calling about the Second Booster, caller further clarified that it was the Pfizer COVID vaccine. She wanted to report how bad the second booster was, if she knew it was going to be that bad then she wouldn't have taken it. She had the first dose and was sick but it was nothing close to this time. She had all the symptoms except a few, but it was very severe, she was running a temperature over a 100 which is high for her, she had nausea, she wasn't even able to get up all night, all she could do was lay there and moan, she felt horrible, she wasn't able to eat for 24 hours or more.  Reporter retrieved her covid vaccine card. Reporter confirmed that all the covid vaccines she got were made by Pfizer. Reporter stated that after the first and second dose she had symptoms but she really doesn't recall what they were exactly, she does know that she had weakness and had to lay down because just felt as if she could not get up, however it was not for very long. She does remember she had difficulty in being upright. Outcome: At the moment she still has a bad headache and weakness, but is starting to get her appetite back. With the weakness she is not up and about, but she can be up compared to before, after the horrible night and yesterday afternoon, she wasn't able to be up, and could only be up for 2-3 minutes. Her Headaches are now slightly improved but it is still a problem, her weakness improved, and her appetite has improved. Getting back to her temperature, when she was finally able to get up at 11AM it was 100 degrees Fahrenheit, this temperature was taken yesterday 12Jun2022.  Her Arm was sore for a few days, but this time, maybe it depends on the way the injection is given but its not as bad as the past injection with the soreness. Concomitant Medication: She is on her regular medications, caller declined to provide her medications stating that it would take too long, she is on 8 prescription. She is on medications for High Blood Pressure, Acid Reflux, and she is on Potassium. Medical Conditions: There is nothing she can think of right now, she has Neuropathy for which she takes medication, the Neuropathy is in the feet. She had no allergic reactions with the vaccines, but she is allergic to certain medications like Demerol and others that she cant think of. She is allergic to mold, ragweed, leaves, and grass, she is on medications for these allergies as well, but they are over the counter products. Caller states that she would like to add that the thing is that this reaction was so bad, that if she has to go through this every future injection then she would rather spend the rest of her life at home, just like how she has through most of this covid time period.; Sender's Comments: Linked Report(s) : US-PFIZER INC-202200838839 similar report from same reporter; US-PFIZER INC-202200838840 similar report from same reporter; US-PFIZER INC-202200838841 similar report from same reporter;
