Additional Information: Patient had developed an eczema like reaction on her body, that she never ever had before. Her question was if there was any possibility that there was something in the vaccine that she could be allergic to. When she would get her inoculations, she did get 5, when she would get them she would have no problems whatsoever except they would itch, the injection site would itch, she remember on one, the itching was from the inoculation on the should area all the way down to her rib, her arm itched, and she don't remember precisely how long it would itched, sometimes longer than others, maybe several weeks. Anyway, now all of the sudden in the last several months, probably almost about 2 years she had now developed an eczema like reaction in various locations of her body and she was just curious, when she read things about the vaccine, she doesn't see any adverse reaction that match that she might she be going through, was there any connection between this eczema like reaction that she developed and the inoculations. She doesn't remember if she developed a similar reaction after her last vaccination, because she did not pay any attention to it, her skin would itch, wash it, and put some typical lotion on it. She thought, was this connected to her vaccination, because her vaccinations itched, in injection site itched and she would tell people that and they will go she have heard of that, did not happen to her, the itching and the rash is very uncomfortable. Her dermatologist had given her creams and soaps to use, so the itching had gone away, but she still had areas of red that she need to make sure that they don't start to itch again. She also asked should she received any more COVID 19 inoculations. She just needed to talk to someone and wasn't sure what group of people to talk to about the suspected adverse reaction.
