Additional information: It was enquired as follows: Caller, female, aged 55, got the bivalent gray cap formulation of the Pfizer BioNTech Covid 19 vaccine last Thursday. Yesterday, on Wednesday morning, six days later, she noticed a red spot on her hip. She was lying on the couch with her legs elevated and her belt was digging into her skin so she thought it was that, but her doctor told her it was shingles. She did not get any reactions from the booster or the other two Covid shots. It was enquired if shingles was a side effect of the new bivalent gray cap booster or not. The following adverse reactions have been identified during post authorization use of Pfizer-BioNTech COVID-19 Vaccine. Because these reactions are reported voluntarily, it is not always possible to reliably estimate their frequency or establish a causal relationship to vaccine exposure. Immune system disorders: severe allergic reactions, including anaphylaxis, and other hypersensitivity reactions (e.g., rash, pruritus, urticaria, angioedema). Question: If it is shingles, she obviously has to start the medicine, the antiviral as soon as she can in order for it to be effective. She just does not want to take the medicine if she does not need it. First dose injected into left arm. On Wednesday morning, 6 days later, had a little rash on her hip and thought was just from belt digging into her skin but she went to her doctor and they told her it is shingles, so she is just reporting that. Indication: to prevent COVID virus, she works in a skilled nursing facility and it was highly recommended to get it. The rash/shingles was first noticed Wednesday morning, so a day and a half ago. AE Treatment: She just took her first dose of Valacyclovir one gram coated tablets, which is three times a day by mouth for a week. The only other thing she has is plantar fasciitis, which was diagnosed mid-May2022. She just got a treatment for that yesterday therapy with Dextrose into her foot for healing, which she has had done before and had not had reactions. She had this, it was already present when she had this done, it does not have anything to do with it. No further details provided about Dextrose, caller declines to clarify what type of therapy she had said it was. Caller asks if this is considered a vaccine adverse reaction report or not.  Follow-up attempts are completed. No further information is expected.
