A 76-year-old female patient received first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection, lot: EN6203), via an unspecified route of administration in left arm on 27Feb2021 (at the age of 76years) as single dose for covid-19 immunisation. Medical history included ongoing fibromyalgia diagnosed in 1999; Covid-19 from 23Nov2020 to Dec2020 (went to the hospital because of pain in her side at night. Was told she had pneumonia and pleurisy, she got it 2 days after her husband did, but hers was a mild case); her husband had Covid in Nov2020 and died in Dec2020 and hemorrhoids (from having babies years ago). Concomitant medication included acetylsalicylic acid, caffeine, paracetamol (EXCEDRIN). The patient had no investigation assessment. The patient scheduled her first dose for 27Dec2021. The patient had questions about it, but the person administering it did not speak English and she said that initially she did not have any reactions while she was there. The patient received the first dose of the vaccine on 27Feb2021 and has a lot of adverse events. After the getting the shot, she woke up at 0400 and experienced shaking (whole body was shaking), trembling out of control, hurting from her neck down to her toes, her joints were achy, hurt, and stiff, her teeth were chattering and couldn't stop, and when she tried to stop that it made it worse, when she got up she had hard time walking, so much that when she had diarrhea, she had diarrhea on the floor, she also noticed that the color of the diarrhea looked red and looked like it had blood on it but she was not sure. After that, she sat down in a chair and noticed that it had blood when she got up and suspected that she had hemorrhoids and bleeding because of the diarrhea. She thought it was a result of the reaction to the shot. She noted that that she had COVID on 23Nov2020 and that she heard that people who had COVID might not need to get the second shot but it was only speculation so she was asking if this was true. She mentioned that she waited 90 days before getting the vaccine as per CDC guidelines and knew that the 2nd dose can be given for 42 days after the first dose. The patient's daughter in law who was an occupational therapist volunteered to fly in and take care of her after the second shot on 27Mar2021 but her 2nd shot was due on 20Mar2021 so she wouldn't be there until then. The patient was having a hard time rescheduling her appointment so asked if there was anything can be done. The patient would prefer not to take the second dose due to the side effects. The patient also reported that it looked like someone who had a stroke trying to walk again, her gait was off and she was kind of jerking. As she would take a step her foot would go down on a slant like it was skidding. She said that this happened one other time to her. It was like she was leaning forward and could not stop herself. When she was able to get up, she went into the living room and sat in her husband's chair and fell asleep until 15:00. When she got up, she noticed a lot of blood in the chair. The patient asked if this was allowed. She went home and took a couple of acetylsalicylic acid, caffeine, paracetamol because she did not have paracetamol (Tylenol), and she went to sleep. She had a hard time rolling and trying to get out of bed. She turned on her electric blankety and her heat. She said that by 0600 most of the shaking had gone away. She felt a little nausea, but got some dry toast. She said that she wanted to take a shower, but she started getting diarrhea from the injection. She fell in the bathroom and could not get herself up for over an hour because she was too weak. When she fell on the floor, she tried to get on a rug because she was still having the diarrhea on the floor. She said that it was everywhere. The next day she called her son and his wife they said that she could be alone for her second shot. She was scheduled for 20Mar2021 for her second dose. The patient had a hard time changing the appointment and her son could not come to stay with her until 27Mar2021. A friend told the patient that on the news it said that a second shot may not be necessary for people who have had Covid-19 already and she wanted to know if Pfizer has heard of this. The patient said that she was kind of wiped out for a couple of days (in 2021) and it was all over now. The doctor's office was aware of what happened and she was told to take extra strength Tylenol before and after the second injection to address these symptoms. The consumer considered the case as non-serious. The outcome of the event fatigue was recovered in 2021 while for the remaining events was unknown.
