Second dose: fever close to 101 degrees Fahrenheit; short term memory is more compromised; constipation/had not had a bowel movement in 5 days; her head feels strange like her head is not quite right; Second dose: hasn't been sleeping well; feels really sick; Second dose: threw up; Second dose: loose bowels that cleared her out like she was having a colonoscopy; Second dose: very nauseous; headache; Second dose: arm hurt a lot; This is a spontaneous report from a contactable consumer (patient). A 59-year-old female patient received second dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Formulation: Solution for injection, Lot Number: EW0162), via an unspecified route of administration in left arm on 20Apr2021 at 15:00 (at the age of 59 years old) as single for covid-19 immunisation. Medical history included ongoing traumatic brain injury, she had major events from 2003, 2005, 2011, minor event in 2016, a small concussion, ongoing migraine, she does report she uses compressed O2 for her cluster migraines. Concomitant medications included influenza vaccine (FLU VACCINE VII) taken for an unspecified indication from Nov2020 to an unspecified stop date. The patient did not receive any other vaccines within 4 weeks prior to the COVID vaccine. Historical vaccine included first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Formulation: Solution for injection), via an unspecified route of administration in left arm for covid-19 immunisation and patient experienced tired for a day or two on 30Mar2021. She was calling about the Covid 19 vaccine. She had her second Covid 19 vaccination and the next day she had a fever close to 101 degrees Fahrenheit fever, she threw up and she had loose bowels that cleared her out like she was having a colonoscopy on 21Apr2021. She was yelling for help because she was feeling so sick and her neighbors didn't hear her, she was alone. She was finally able to get herself off the bathroom floor. Her fever broke the next morning. She still has a headache on 20Apr2021. She's still feeling very nauseous on 21Apr2021. She just feels really sick. She had not had a bowel movement in 5 days, she took Colace and she had her first bowel movement today since the vaccine caused her loose bowels. But she survived and she's happy she got the Covid 19 vaccine. She's praying she doesn't have to get another Covid 19 vaccine in a year. If she has to get another Covid 19 vaccine in a year she's going to decline. She's wondering because she has a history of traumatic brain injury and she doesn't think her immune system was very strong. She was on disability because of her traumatic brain injury. She does report that her short term memory was compromised because of her traumatic brain injury and after the Covid 19 vaccine she feels like her short term memory was more compromised. That could be from a number of reasons though. She still has the headaches. She reports after the vaccine things are worse with her remembering things. When probing suspect product information, she reports she received both her Covid 19 vaccines in her left arm. She reports with the first dose she hardly noticed any symptoms. She was maybe tired for a day or two with the first dose. She experienced no problems with her arm. She started feeling bad after her second dose around 3:00 PM and she went to bed with a headache. She might have gotten feverish that same night, 20Apr2021. She definitely remembers the aftermath of the next day, 21Apr2021 because that's the day she couldn't get off the floor in the bathroom. She missed the toilet and was having to throw up and sit on the toilet at the same time. She grabbed the garbage can in her bathroom and she missed throwing up into that too. She reports now she has constipation so she started drinking prune juice and taking Colace and that was helping. She still has nausea after eating and her head feels strange like her head was not quite right. She experiencing short term memory loss but that could be from lack of sleep. She hasn't been sleeping well since she received the Covid 19 vaccine. She hardly slept the night she got the second vaccine. She had a hard time falling asleep because her arm hurt a lot on 20Apr2021. Her arm was not bothering her now, that went away. When probing if she had seen her doctor or had to go to the emergency room, she reports she will see her doctor if her symptoms persist. She reports she received the flu vaccine in Nov2020 because she thought if she got the flu vaccine then if she got the Covid 19 virus, the Covid 19 virus wouldn't be so bad. She does report she had an MRI scan yesterday, 26Apr2021 for a mass on her sacrum. She doesn't know if the MRI interferes with anything. She had symptoms prior to receiving the Covid 19 vaccine. Her doctor found the mass on her sacrum 6 months ago and the MRI was a follow up for that. She doesn't have the results of the MRI yet. Her doctor told her the mass was so small he wouldn't do anything about it. She reports it's a 7% chance it's cancer. She hopes it isn't cancer because she's already had two biopsies this year. She's asking what's the best thing to take for a little nausea, can she take ginger. The patient underwent lab tests and procedures which included body temperature: second dose: fever close to 101 degrees fahrenheit on 26Apr2021 Second dose: fever close to 101 degrees Fahrenheit, magnetic resonance imaging: mass on her sacrum on 26Apr2021 Mass on her sacrum. The patient did not visit emergency room or physician office. No relevant tests were performed. The patient did not received treatment due to the events. The outcome of second dose: fever close to 101 degrees Fahrenheit, second dose: arm hurt a lot, second dose: threw up, second dose: loose bowels that cleared her out like she was having a colonoscopy, feels really sick was unknown, while with other events was not recovered.  No follow-up attempts are needed. No further information is expected.
