The patient experienced on 07Mar2021, low grade fever, weakness, chronically dehydrated and cough; on 15Mar2021, rash, acute pain and with deep breaths; on an unspecified date, no desire to eat or drink. Seriousness criteria of these events were reported as disabling. Patient reported that was having major problems, a delayed immune response. Told everybody if this keeps up she was not going to make it. It was wearing her down and she was not going to survive. Occurred after second COVID vaccine. She is active, goes to pool, and does different things. Had vaccine on Thursday and was ok until Sunday. Started Sunday with low grade fever. Kept being low grade and never got to 101, 102, or 103. She didn't take ibuprofen. Usually takes ibuprofen once a day for routine aches and pains. Having weakness. Had no desire to eat or drink. She waited a couple days, but then called her doctor. Doctor's office wouldn't give her an appointment. Stated this wasn't the routine and has been going on for 10 days. This was too much. Two days later, caller's daughter-in-law took her to a place like an ER. A bunch of tests were done. She asked for an IV because she was chronically dehydrated. Weakness was getting to her. After seeing the doctor in the mini surgical ER, she didn't feel any better. She felt the same. Same nausea, weakness, low grade fever, the whole thing. Decided to see her regular doctor. Stated it wasn't her chest. Wanted to be told what was going on. Her regular doctor didn't order any labs. She was given a steroid shot. Thought she was in deep doo-doo. Stated this was not a good sign and she was not going to make it. She woke up yesterday with a rash covering her entire body. She had no clue she had the rash. Never saw the rash. Rash didn't itch, but she still had it. After steroid shot from doctor, she felt a little bit stronger and thought maybe she was going to make it, but then started getting severe pain. Patient was used to having aches and pains that went along with old age and her osteoarthritis. This was severe pain as if she fell and hurt her ribs. It hurts to take deep breaths. Her hip and knee were killing her. It was acute pain, not normal pain. This morning stated she couldn't take it and was going to take ibuprofen, which was not the best for her. She didn't want to eat, but tried to have food in her stomach to take the ibuprofen. She cannot take good deep breaths because of the soreness in her ribs. Thought something in her body was having a delayed immune response and her gut told her it was not good. For low grade fever, did not take ibuprofen, 07Mar2021 was when she started feeling yucky, she wanted to see how she felt and her temperature never really got up, stuck it out, normal temperature for her was 97 or lower, her temperature once in a while would range from 98 to 100.3 or 100.8, she cannot take paracetamol (TYLENOL). For weakness, noticed right away, felt a little better after steroid, had not been out of her door except to the ER. For chronically dehydrated, clarified she had no desire to eat, usually drinks coffee and tea in the morning, but now had no desire, was making herself drink, felt something wasn't right beginning on 07Mar2021, everything went south and got worse, clarified it really wasn't nausea, but no desire to eat or drink, doctor today gave her ondansetron (4mg) which didn't help and made it worse, eating and drinking didn't make her sick, just didn't want it. She had labs done in the ER and was told her labs weren't really that off for her to be that dehydrated. Asked for an IV because she was not drinking what she normally drinks, didn't feel any better after the IV. Rash covering her whole body, but didn't itch. Acute pain and with deep breaths began evening of 15Mar2021, seemed the same today, she just took an ibuprofen a little while ago and was feeling better. Patient also mentioned that realized her body was trying to get monoclonal antibodies and resistance to build up her immunity so that if she ever got infected with COVID virus she could fight it, it was just not working, it was not doing its thing, she was having a delayed immune response, was very worried about that, going on 8-9 days and it was weakening her by the day, didn't think she could take this too much longer. Clarified the COVID Vaccine wasn't working and her body couldn't get its act together. Patient had a slight sore arm after the second dose, never reacted at the injection sight, it was strictly internal, which kind of scares her, something was not right, was having the rash, pain, and severe weakness. Was not expecting any kind of problem. Didn't think too much about the second COVID Vaccine. Stated people were like "oh that second shot." If she didn't get better soon she is not going to do well. Cough was a dry, tight, non-productive cough, lungs were checked yesterday and were clear, felt like all of a sudden she has an urge to cough and nothing comes up. For steroid shot, didn't know if it was dexamethasone (DECADRON) or not, made her feel a little stronger for the day, but then brought on severe aches and pains in her joints and ribs, did not have this until the steroid shot. Patient said that didn't take ibuprofen the first couple days because she didn't want to mess up the immune response starting in her body, asked doctor about immune globulin for her delayed immune response, but doctor shook his head, knew that people with autoimmune are ordered IGE or IGG to test the immune system, asked doctor about this, but he shook his head. Stated she didn't think a CBC with different was performed at the ER, confirmed she was only in the ER after the second dose and was not admitted to the hospital. As of 17Mar2021, she stated then two to three days after that she woke up with rash over her entire body that showed up overnight, that alarmed her even more of course, no itch or nothing, no clue it was there until she washed off and could see it, she had never had a rash before, her arm never got red, but she had a low grade fever, stated now didn't know if good or bad, cough, not productive, some urge to cough, no appetite, not eating or drinking, and increasing weakness, today she couldn't say anything was different about her rash maybe slightly faded but she didn't feel any better, she did get a steroid shot when she went to doctor yesterday and that made her feel less weak. As of 18Mar2021, patient stated that had no reactions for the 1st 2 days following her 2nd dose however she started to feel ill, low grade fever that never went above 100. General feeling of the flu; aches and pain, which she had before but more than usual. She had no urge to eat. Tried to see her doctor when it had been going on for 5 days but they were not concerned. By that Friday, she went to the hospital. They found nothing wrong in her lab tests but she asked them for I.V fluids since she hadn't eaten or drank anything. On Monday, she went back to her initial doctor because she had a rash all over her body, it did not itch and her injection site had no redness. She was given a steroid shot, today she might be feeling a bit better. She lost 10 lbs. She had to stay inside for the past 10 days, except for doctor visits, although she was usually an active person. She would like to know how long the side effects would last.
