He stated they did not have any side effects with the vaccines but maybe sore at the injection site for the previous vaccines. Agent clarifies there is only supposed to be just one bivalent dose given. All previous doses were manufactured by Pfizer and they had no other negative reactions to any of them. Had all vaccines, from shingles to whatever. The minute they bivalent COVID-19 Vaccine became available in their area, their Pfizer access was at (Facility Withheld) instead of the (Place withheld). Took first bivalent COVID-19 Vaccine on 09Sep2022. Today when having their annual wellness, primary visit with primary doctor, their doctor said the new variant COVID-19 Vaccine was out and their doctor took it. Their doctor states that patient and his wife are always staying current that maybe they wanted to get the new variant COVID-19 Vaccine. Caller and his wife took the variant COVID-19 Vaccines today, went home, looked at their cards, to find out it is the same bivalent COVID-19 Vaccine. Caller would like to contact his primary and tell him what he's done. Their primary doctor was an innocent bystander. Caller was assuming that eventually they will end up with some variation of the booster variants every year. He was guessing it's going to be like the Flu shot. Received a second bivalent COVID-19 Vaccine: Time: about 8:00AM Treatment: None Caller and his wife both had the primary two doses. Then a 3rd dose that they thought was a booster dose. The 4th dose was actually a booster. The 5th dose was a bivalent COVID-19 Vaccine. Then today, received another bivalent COVID-19 Vaccine. Patient and his wife were the first two to get a dose today. Indication: to stay current and their doctor wants them to stay current As soon as the bivalent COVID-19 Vaccine came out in the Fall, after they got it, their doctor took it also. Concomitant products: nothing has changed Medical conditions: Nothing necessarily. He had noticed references to heart issues and he has a pacemaker. Pacemaker placed: sometime in the year of 2021, but he had issues before the COVID-19 vaccines More recently he had atrial fibrillation and was given two medications. The atrial fibrillation was light, so they didn't want to shock his heart. Appears the atrial fibrillation is gone. Atrial fibrillation: had symptoms of that at night before receiving the COVID-19 vaccines. Thought muscles were twitching before they discovered it was tied in with the heart. When he would lay on his on left shoulder, it felt like a light vibration. He was given the pacemaker, then had Atrial fibrillation, then given the medicine to take care of it. Investigations: none primary doctor and specialist are really good about keeping bloodwork up. Caller gave blood today. Clarifies caller and his wife are the reason they got the bivalent COVID-19 Vaccine shot today. They didn't think they had it before. Patient's wife states when you are near 80, your mind half-goes. They forgot about the first bivalent shot at.; Sender's Comments: Linked Report(s) : US-PFIZER INC-202300029209 same reporter/patient, different events/doses;
