The event "he developed tendonitis" required physician office visit. Relevant laboratory tests and procedures are available in the appropriate section.  Additional Information: He states he was injured by what he suspects to be the second booster. He then states that it was after the second vaccine and not he booster. Caller states that the booster did cause some reactions too but, were not as substantial as after that second vaccine. That was still ongoing. Caller states that he had other symptoms that he got after the booster dose. That was in Oct2021, he developed tendonitis and he never had tendonitis before and, both of his hands were asleep. Clarified that the caller had the booster 06Oct2021. He states he was a little bit leery about getting the booster. He had multiple antibody tests done and he states that the got that done probably late Sep2021, early Oct2021. He has been to a back surgeon a back doctor, a rheumatologist, a cardiologist, and was waiting to go see the neurologist. They really hadn't gotten to the bottom of it and he felt hesitant to take the booster. Now, he wishes he hadn't. He states he has not tested positive for Covid and has been around his 8 grandchildren and 6 kids. Everybody has gotten Covid but neither himself or his wife have tested positive for Covid. Indication: Caller states it was what he was supposed to do. He was diabetic and was 65. He states he had LADA, late stage, type 1 Diabetes. Patient blood sugar had been ok and 14 years ago, he was diagnosed originally with Type 2 Diabetes and had tried some medication. He then went to, no the epidioloigismt but another type of doctor, and they checked the insulin and discovered that his pancreas no longer creates insulin. He was diagnosed late in 2008. Caller states his A1C has been 6.5, or 6.7 but, always under 7 for the last 14 years. Medical Conditions: Caller states he had a heart valve replacement in 2019 which went like clock work. It was pretty phenomenal. It was a Tavr, which they go through the leg, the artery in the leg and replace it in the aortic valve. He was there for like 1 night. It was like magic. Tests: Caller states they did find small nerve fiber damage in the report from the neurologist. They did MRIs and did an MRI with injection. They found some arthritis in the spine but not anything life shattering. There is nothing they really recommend from there. after dose 2 They tried some steroid injection and caller states he sort of argued with that doctor. With his diabetes, the steroids are not good for people with diabetes. He states his blood sugar went haywire for 2 weeks so, that was not a good idea and it didn't really help. Caller states he does not remember the name of the steroid or have the NDC, LOT or EXP to provide. Did any AE(s) require a visit to: Emergency Room was reported No and Physician Office was reported Yes. If Yes, which AE(s) couldn't walk, legs numb and wouldn't react, It affected his ability to walk and kind of lost the use of his legs, tendonitis. Prior Vaccinations (within 4 weeks) was reported No. Prior to that, he may have had the flu vaccine, 5 months before. He always gets the flu vaccine and has never had any adverse effect. AE(s) following prior vaccinations: None and he has had plenty of vaccines for travel, including for yellow fever, sating he goes to places that require vaccinations. Family Medical History Relevant to AE(s): None that he is aware of. He states the report was not complete, stating that after that, he went to the rheumatologist and he does not have an auto immune disorder which was a good thing. The neurologist did enter information prior to that. Caller states it was hard to navigate that data base. Caller asks if we are familiar with the fact that 5 percent of the lot numbers can contribute to 90 percent of adverse effects. Laboratory test: Consumer stated, "Yeah antibody test, yes he got three and that's a curious conversation well. Prior getting the booster in Oct, I went for the antibody check. Roughly 6 months after the second vaccine, he went for my antibodies check and they were very low. They were like 300 an arbitrary number it's obviously more, it's better The smart thing to do at that point was he had three or four antibodies check. The first was close to 300, he don't know the exact number. After the booster, it was 2500 and then three months later, he just had a check probably a month ago and it dropped down back to like 400 so, the booster lasted may be 90 days. He do not, he got a history of antibody test or it was good. he guess it was for 6 months. he don't really any had a check for first 6 months but it dropped down automatically after 6 months. he got booster it was 2500. he get check began in Jan till Feb it got dropped back to 400 so, it dropped dramatically." (test results were not clarified appropriately hence, not captured) Further assistance: Consumer stated, "No actually the numbers on Antibody test were done in Mar So he have done in Dec so two months after he got the booster, it's 2500 and then in 14Mar2022 this year, the number dropped to 245 so, it's pretty much more low. he just expect now that he just not needed it any more or he need the m RNA. No follow-up attempts are possible. No further information is expected.
