Additional information: Caller reported some side effects from the Pfizer-BioNTech COVID-19 Vaccine, gray cap, Bivalent. She has experienced dizziness, no balance, nausea, vomiting and jitteriness. At the moment of the call, she mentioned to be only experiencing the jitteriness and nausea/vomiting. She wanted to know how long the symptoms she is experiencing will last. This was her first Pfizer product she's had. All other injections, first two doses and boosters, were Moderna COVID-19 Vaccines. Had Pfizer Bivalent the day before yesterday. Was told by the administrator it made no difference if her previous doses were Moderna. Her husband got the Omicron too and he has had no problems. Clarified the facility was just advertising the Pfizer Bivalent booster dose as the Omicron. Confirmed caller and her husband were not COVID-19 positive with the Omicron variant. For caller, within 26 hours of taking the Pfizer Bivalent booster dose shot, she started having severe dizziness and no balance, almost like vertigo. Was vomiting and it finally stopped about the middle of last night. Vomiting lasted for about 4 hours. She's still just as nauseous this morning but has nothing to get rid of. Was just jittery and shaking all over. Wondered if that needed to be reported Pfizer Bivalent booster dose was new. Read some of the symptoms but didn't see the ones she was experiencing. The Pharmacist gave her the injection and advised caller to report it. Dizziness and no balance, like vertigo: It was not as bad. It was like she had been on a roller coaster and has a swimming head today. Attempted to clarify, caller states it's like her equilibrium is off. Her balance was back, she was being careful. Vomiting has stopped, nauseous feeling is still there. Feels jittery just jerky inside. Vomiting began about 4:30PM and stopped about 9PM yesterday. Guessed she had recovered, not throwing up, just nauseous feeling. Nausea began immediately. Had been feeling fine all day. Jitteriness, shaking all over since she got up this morning. Woke up about 4:30 and was really nauseous while lying flat. Got up and came to the den and propped her head up and it helped. Then went to bed for a while. It's better but still, doesn't know how long she can sit up. No treatment was given. With the first booster dose manufactured by Moderna, it lasted longer than 24 hours, like a case of the flu and that was it. She did not go to the doctor, just rested and that was it.
