The following information was reported: NAUSEA (non-serious), outcome "unknown"; CHILLS (non-serious), outcome "unknown"; PYREXIA (non-serious), outcome "unknown", described as "fever".  Additional Information: It was reported that the caller, a female almost 72 years of age, has had 5 previous shots of the Pfizer COVID vaccines. She is calling about the new one that was just released but nowhere has it yet. She had a different reaction to each vaccine but would like to stick with Pfizer because that is what her body is used to. She does have a lot of allergies. The first shot she had a very severe reaction to. She developed high blood pressure, and she had always had low pressure. Her blood pressure was usually 100/60 and after the first shot it went up to 159/85, she thinks. It was like that for quite a while, until right before she had to get the second shot and it got better. She called the Pfizer reaction line, and they told her that it happening to people but its temporary and if you already deal with that issue the shot could make it worse, but she never had that issue before. So, she went to the heart hospital to go get checked out. She was having heart palpitations and PVCs bad. She could feel them. She always gets them but doesn't feel them. But she didn't have that strong of reaction again like she did to the first dose of the Pfizer COVID vaccine. When she went to see the doctor and told her about it, the doctor, who is thin like her, said she got the Moderna COVID vaccine, and she also was having heart palpitations. The subsequent doses it was always the nausea and the chills and things like that , fever. She is one of five sisters, they're all over the age of 60. Two of them didn't get vaccinated against COVID, they don't believe in it or trust in it. The three sisters (herself included,) who have been vaccinated have not had COVID, or if they've had COVID the symptoms were so mild they didn't notice.  The youngest sister has had COVID 3 times; the most recent time about 2 weeks ago. At first, she thought it was allergies. It presents just like a cold. She went over to oldest sister's house to fix a sink. She thinks the youngest sister gave it to the oldest sister. She isn't sure but they hardly go anywhere Did not clarify if oldest sister was vaccinated or not.  The oldest sister and her husband both got COVID and had to be hospitalized. Then she had a heart attack Sunday before last. She ended up going back to the hospital and had to have emergency surgery. Her left artery was clogged with blood clots. The doctor told her they were a result of clots that were formed during the first week of her having had COVID. The doctor said they have been seeing a lot of this over and over in this strain, and it completely clogged her left artery. When the youngest sister spoke with the doctor, he was adamant that the blood clots were caused by the COVID virus, he had no doubts about it. The youngest sister informed him that she had also just had COVID, and he recommended her taking a baby aspirin to prevent blood clots because the clots can form long after you're better, even 8 months later. But her sister thinks the vaccine has the live virus in it. They were able to go in and do what they in. She was unable to get a stent put in because she's had a brain aneurysm before and survived it. She couldn't see them or go to the hospital. One of the reasons she wants to get the vaccine is to avoid getting COVID and developing bad clots like her sister.
