Additional Information: The patient reported that she had received 4 shots of COVID 19 vaccines at the moment. She referred to the Bivalent gray cap vaccine as her potential third booster. She asked whether the Bivalent vaccine have some sort of extra adjunct material to make it stronger or why it was called bivalent. She also asked if there was something different in this new vaccine compared to the first three doses that she received. She was already in her appointment to receive a dose of the new Bivalent gray cap vaccine, but when she read the vaccine was not FDA approved, and the term "Bivalent", she decided not to receive the dose as she had arthritic knees not she does not have good bones. She asked if she could be irritated by receiving the 4th dose with the bivalent. She felt very tired the next day with her previous doses and asked, what was going on with the fatigue. She asked if she could be fatigue with the new bivalent. She mentioned that it was concerning, but that probably apart from being more tired that she has been with the previous vaccination, she suspected she would not suffer from anything unusual, and that she would make an appointment to receive the vaccine. She got information from some institution that this new bivalent vaccine was only tested in 8 mice and no clinical trials were conducted. She asked if this was true and what was mRNA. She asked about the ingredients of the Bivalent vaccine and for the function of the polyethylene glycol how long does it take for the body to get rid of the polyethylene glycoll contained in the vaccines.
