Additional information: The caller received pneumonia shots and she is not positive of the name of the product she received and did not know if there is more than one pneumonia vaccine. She called where she received the product and they told her it was Pfizer but she does not have the NDC. Agent said she thought maybe she could be talking about Prevnar 20 but was not sure. The caller received this on 26Feb or 27Feb and has had persistent pain intermittently several times a day and redness on her left arm where she got the injection. She wanted to know if this was normal. The caller stated she knows it was the pneumonia shot but did not know which one she received. She stated she would have to call her doctor to see which one it was, she just knows it was a pneumonia vaccine. She figured since Pfizer manufactured it we could provide tips on how to resolve symptoms or tips on what to do about ongoing symptoms. She stated obviously all the symptoms are posted online. Caller states she is calling to report an adverse reaction that started right after the shot. Caller reports as soon as she got the shot, within a day or two, her whole left upper arm started to swell and it got hot. She states the Company that gave her the shot wouldn't see her, they made her go to an Urgent Care and she got antibiotics. Caller states that was at the end of Feb2023. Caller states she still has a red mark on her left upper arm and she will be sitting and she gets tightness in her arm where she got the shot, it has not gone away. Caller states she believes she got the shot on 26Feb2023 or 27Feb2023 and the red mark and pain have persisted. The pain isn't constant but she feels it several times a day. Treatment: Antibiotic. Caller states her sister who is a nurse told her she should report it to whoever created the shot, and when she called the people who gave it to her they said the Manufacturer was Pfizer. Caller states she doesn't think it should last this long and she doesn't really know what to do about it.  The information on the batch/lot number for pneumococcal 13-val conj vac (dipht CRM197 protein) has been requested and will be submitted if and when received.
