Her husband call (Phone number withheld). Caller was taken to the Hospital and was kept for almost 24 hour for observation. She had a severe reaction to one of those shots. Caller mentioned she just want to know if she got the original or the new vaccine. Caller also added: Her original series was completed on 30Aug2021 with a third dose. She also stated she never had bad reaction to any Pfizer shot and she is upset because she requested the latest shot at (Withheld) but apparently was given and old shot. Caller finally added his husband also received the same shots and did not have any reaction and that she had reacted Prevnar 13 and put her in the hospital before, but never to any COVID shots. She had really bad reaction after receiving the 2 vaccines. Was dizzy and vomiting, had to be taken to hospital. For 24 hours, was in hospital in observation. Clarified with caller, details provided by transferring agent. First shot was Pfizer Covid shot, second shot was RSV shot. That one stung for a while, arm is still sore. Around middle of afternoon, maybe closer to 3PM, started getting really dizzy. Dizziness: Started the afternoon she got shot, around 11:30 am, started soon after, than the nausea. Didn't have much to eat at supper. Had nausea between dizziness chest pain. Already has ICD implanted, is in Afib all the time. Husband called, they came out, next thing she knew, was on way to hospital. They kept her in observation, that could have led to regular admission. Clarified, she was not admitted to hospital. They kept her in observation room. Left yesterday, 12Sep2023, was discharged around 4:40PM. Was sent home to recuperate. They gave her 2 scripts because, she had 2 bags IV antibiotics, does not know which ones, they administered to her while at hospital. In additions, they gave her something to stop the nausea and vomiting, the Zofran, that might have been a pill. Clarified, the nausea and vomiting started that same day she got shot, 11Sep2023. Husband called and was taken to ER by ambulance same day, 11Sep2023. Was still vomiting when EMT showed up. Dizziness, vomiting stopped when they gave her the Zofran. They also drew blood for blood cultures to analyse what ever shot was given. A lot of needles were given to her. On final discharge papers, they said, possible pneumonia. They did chest x-rays and echo. Cardiologist came in, will follow up with them. They monitored her ICD, to make sure it was functioning properly and nothing was wrong with that. Was supposed to get the new shot, apparently found out by pharmacist, she got the old one. Chest pain: Thought the chest pain was due to all the coughing going on and vomiting. Clarified, the coughing had been going on a couple of months, was not something new that started after having these vaccines. It could be related to the heart disease that she has or could be the pneumonia. Concomitant Products: The only other shot was for pneumonia, was in hospital. Flu shots were fine, never had reaction until pneumonia shot, the Prevnar 13, when that came out, was the left arm. Cellulitis set in within 20 minutes, almost immediately. Thought that is what caused her to be hospitalized, the cellulitis. That was in 2017, she thought. They only kept her, probably 1 or 2 days. They have that as part of her allergic reactions to pneumonia shot. She was very tired.; Sender's Comments: Linked Report(s) : US-PFIZER INC-202300300000 Same Patient, different drug/AE;
