The patient received the Pfizer COVID-19 vaccine booster on Nov2021 where she developed a rash and still has itching in the injection site arm 2 years later. Her oncologist suggested that she shouldn't take more of them. The patient wanted to know if that's normal to have that itching for 2 years. She wanted to know the guidelines on getting another Pfizer COVID-19 vaccine. The patient has a history of metastatic breast cancer and is immunocompromised. The patient further clarified that she had the rash that afternoon of the injection. The thing that she has was the itching down that one nerve down the left arm and shoulder consistently for 2 years. It has been a residual side effect that's been continuous for 2 years. This happened when the patient was 68 years old. Now, she is 70 years old. Stated that she had the first 2 shots in Feb2021 and Mar2021, then booster in Nov2021. Stated that she did fine with the first 2 shots. She has been on Ibrance from Pfizer for 7 years and is doing very well. The patient explained that for about an hour after she received her booster dose, she had hot flashes because of the vaccine. About 2 hours later, when she was cooking, she got really hot and ripped off her shirt. She was broken out all over her whole torso, it was red and rashy and broken out. She called her husband, and he picked up some Benadryl and took it. Within 3 hours, it was completely gone. It was not itchy. After that, she noticed, and is still noticing even after almost 2 years, that starting with the exact middle of her backbone and down her left arm and shoulder of the arm that got the vaccine, it was really itchy, like an allergic reaction does. Explained that it was just down that one nerve, not an inch past of it on her neck on the other side. Stated that she is not sure if it started that same day as the rash or if it was a week later. It was not 24/7. No treatment was received for the itching. Stated that it is not like it happens for 3 hours at a time, but it happens everyday and lots of times of those, is before going to bed, like when a person gets a fever late at night, that is when she notices it. Stated that people have told her that she is scratching her arm, but she does not notice it much because it was a habit now. There was no pain. The patient has not read about anyone having a long-term reaction like that. She wanted Pfizer to know that she is experiencing that and to see if there are any other cases. Stated that her oncologist suggested to not take a second one and so did the ER because she called the ER and told them what happened. The patient has a history of allergic reactions. She can't take Lidocaine or Novocain, because she things that they are linking it to the epinephrine or preservative because she can't take carbocaine. She can't also tale Neosporin ointment and can only take Halog ointment, but if she uses Halog cream, she gets contact dermatitis in a heartbeat. These started from about her mid 30's. The patient stated that she reacts to Thimerosal which used to be a big preservative or extra agent, she was allergic to it. But she recalls calling Pfizer before she took the vaccine to see if it was in there and said that it was not. Stated that other than metastatic breast cancer, she is in good shape physically. Therapeutic measures were not taken as a result of vaccination site pruritus. Therapeutic measures were taken as a result of rash, erythema.  The information on the batch/lot number for bnt162b2 has been requested and will be submitted if and when received.
