The patient received her first dose on 10Mar2021 and 2 days after she started having chills and feeling feverish. The patient had fever twice. A day before (18Mar2021) she had a slight fever, runny nose and chills. On 19Mar2021, she had chills, achy and felt like she has a fever, but she doesn't have a fever. It was like a muted flu; it was not horrible but can be debilitating at times because she can't function and was always cold. She constantly has chills, then her nose feels like it is burning on inside and she sneezed a few times. She added that 3 days before getting the vaccine (07Mar2021) she was not feeling well and had a rapid COVID test done and it was negative. The day of the actual day of vaccine the patient was okay. The patient has lupus and a blood clotting disorder for which she takes apixaban. She continued that she has not been out of the house since Mar2020. When she got the shot she had a little heart palpitation. She does not know why she was feeling this way after all these days. She wanted to know how long this would last and should she get tested for COVID. There was a lady that was sick when she got vaccinated and they allowed her in. The heart fluttering felt like it was in esophagus at first. It felt like it was going down her throat. It lasted only a couple of hours. She heard that from other people (her sister). No ER or physician's office required. The patient wanted to know how long the side effects were going to continue. The patient wanted to postpone her second dose until after Easter and her birthday, she did not want to be sick during that time. She has re-scheduled her second dose for 05Apr2021. Her son was getting married 27Jun2021 and she saw a study that immunity was still high at 62 days. The patient wanted to know if she would still have immunity or high antibodies on 27Jun2021 or would it still be effective. The outcome of achy, runny nose, like a muted flu, always cold and had a little heart palpitation was unknown. The patient has not recovered from chills and feeling feverish.
