The following information was reported: PAIN IN EXTREMITY (non-serious), outcome "unknown", described as "She just had a little bit of a sore arm".  Additional information: Reporter had the 3 shots of Pfizer Covid-19 vaccine and she had no problem with the vaccine but was wondering if Bivalent and the old vaccine are just the same. The caller wanted to know if there were any differences in the Pfizer BioNTech Covid-19 vaccines monovalent and bivalent for adults in terms of ingredients. No one can tell her what is different and if the new one will cause a problem. One HCP has told her not to get the Bivalent and another one is saying to get it. The caller stated her doctor was worried about her getting the Covid vaccine because she had seizures with vaccines when younger and was hospitalized and had loss of muscle control so she never gets pneumonia vaccines and flu vaccines. They don't know what shots she was given that caused such a severe reaction but just know that it was vaccines. When this one came out she was really afraid to get it. They had a doctor and ER tech to wait with her because they knew she could have complications, but she never did. She just had a little bit of a sore arm, very slightly. She had 3 of the original Pfizer covid shots, two primary and a booster. Her last booster dose was in Jan. They say that the original (Covid vaccine) is just as good as the new one at fighting.  She has a lot of drug allergy issues to anything. They have to be cautious with whatever they give her. There is only one antibiotic she can take. Everyone she knows that has taken the Moderna (covid vaccine) has had issues but no one with Pfizer has. Her family got Pfizer Covid vaccine primary series and boosters and all four of them still got Covid, but they did not have long term problems with it or didn't get that sick with it. She declined providing their information. The caller stated there are still conspiracy theories people saying "don't get the shots they are killing us" (referring to covid vaccines).  The information on the batch/lot number for BNT162b2 has been requested and will be submitted if and when received.; Sender's Comments: Linked Report(s) : US-PFIZER INC-202201286932 similar report from same reporter,;
