This 75-year-old female patient received first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, lot: EN6203) via an unspecified route of administration in the left arm on 06Mar2021 at single dose for COVID-19 immunization, Covid-19 vaccine mrna (mrna 1273) (MODERNA COVID-19 VACCINE) via an unspecified route of administration for COVID-19 immunization (not administered). Medical history included high blood pressure and underactive thyroid. Concomitant medications included celecoxib (CELEBREX) and acetylsalicylic acid (BABY ASPIRIN). The patient received her first dose of Pfizer-BioNTech COVID-19 vaccine on 06Mar2021. At the vaccination center she was told she received Moderna's COVID-19 vaccine, the Lot number documented on the vaccination card is EN6203, she would like to confirm if this Lot number belongs to a Pfizer-BioNTech vaccine. Her next dose was scheduled for April 5, 2021. As later confirmed that the vaccination card contains incorrect information, this Lot number belongs to a Pfizer-BioNTech COVID-19 vaccine, instead of Moderna's vaccine (as documented). Agent mentioned the patient "had some side effects from the vaccine". The patient explained that the vaccination center was administering COVID-19 vaccines from Moderna and Pfizer-BioNTech, the documentation error may have repeated in other patients.  Patient stated that "when I talked to the girl am I getting a Moderna and my son heard her say yes, and I said - Okay. Now that day they are doing second shot on Moderna and the first shots on the Pfizer. Here she was telling me twice that I have got Moderna, but it's written on card here that I got a Pfizer. She actually put me on Moderna time frame not on Pfizer. I should have had the shot if I was on Pfizer. I think she was thinking that it was Moderna shot and that my time laps would, the question is, I am out 30 some days". The patient stated she had some side effects after her shot. She did have some fever, the little bit of chills, the headache. She did get a lump under her arm of the site where the shot was given. And that's fine, she knew that a lymph node was down more there than it was other. She had already talked to her doctor and was told that when she was going next Monday to get the other shot, just shoot the other arm. So, that's rectified. Patient stated probably right after, her arm about 4-5 days, after, maybe up to a week, she got a feeling of warm herself, but after 3 to 4 days her arm started getting sore, she noticed the lump coming under her left arm where she (incomplete sentence). Treatment included patient had hot water on it. She was not doing much anymore. She was taking Tylenol for probably a week or week and half between here, and that probably did help. The outcome of events was unknown.   No follow-up attempts needed. No further information expected.
