When she would get her inoculations, she did get 5, when she would get these she would had no problems whatsoever except they would itch, the injection site would itch, she remembered on one, the itching was from the inoculation on the should area all the way down to my rib, her arm itched, and she did not 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 did not see any adverse reaction that match that she might be going through, was there any connection between that eczema like reaction that she developed and the inoculations? Caller mentioned her last dose was a booster and was administered to her on 04Oct2022. Caller mentioned that she did not 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. Caller also mentioned: she thought, was that connected to her vaccination, because her vaccinations itched, in injection site itched and she would tell people that and they would go "she had heard of that, did not happen to her", that itching and that rash was very uncomfortable." Caller also stated: 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 needed to make sure that they did not start to itch again."
