tired; wanted to sleep feeling; I still feel rotten/ It probably just aggravated what I already have; I have aching in my shoulders, across the top of the shoulders; it feels like a flu/ feels like she has the flu; not feeling good for a couple of days; This is a spontaneous report received from contactable reporter(s) (Consumer or other non HCP) from medical information team. The reporter is the patient.  A 79-year-old female patient received BNT162b2, BNT162b2 omi ba.4-5 (BNT162B2, BNT162B2 OMI BA.4-5), on 22Sep2022 as dose 4 (booster), single (Lot number: GH9694) at the age of 79 years, in left arm for covid-19 immunisation. The patient's relevant medical history included: "collagenous colitis" (unspecified if ongoing). There were no concomitant medications. Vaccination history included: BNT162b2 (First dose Pfizer Biontech MRNA covid vaccine, Lot: EN5310 (print of lot number), Expiration: unknown), administration date: 13Feb2021, when the patient was 78-year-old, for COVID-19 Immunization; BNT162b2 (Second dose Pfizer Biontech MRNA covid vaccine, Lot: EN6208, Expiration: unknown), administration date: 13Mar2021, when the patient was 78-year-old, for Covid-19 Immunization; BNT162b2 (Booster dose Pfizer covid vaccine, Lot: FH8020, Expiration: unknown), administration date: 02Nov2021, when the patient was 78-year-old, for Covid-19 Immunization. The following information was reported: ARTHRALGIA (non-serious) with onset 2022, outcome "unknown", described as "I have aching in my shoulders, across the top of the shoulders"; CONDITION AGGRAVATED (non-serious) with onset 2022, outcome "unknown", described as "I still feel rotten/ It probably just aggravated what I already have"; INFLUENZA LIKE ILLNESS (non-serious) with onset 2022, outcome "unknown", described as "it feels like a flu/ feels like she has the flu"; FEELING ABNORMAL (non-serious) with onset 2022, outcome "unknown", described as "not feeling good for a couple of days "; SOMNOLENCE (non-serious) with onset 2022, outcome "unknown", described as "wanted to sleep feeling"; FATIGUE (non-serious) with onset 23Sep2022, outcome "not recovered", described as "tired".  Additional information: After receiving Pfizer-BioNTech COVID-19 Vaccine Bivalent the patient was tired, wanted to sleep feeling and queried what could be done about it. The patient got her booster last Thursday and she still felt rotten, it was something that had to wear off right. The patient had collagenous colitis and underwent colonoscopy on 01Jul2022. Had colitis problem for months and then was diagnosed as collagenous colitis. She queried and thought that diarrhea was one of those things (symptoms) that can go along with booster. It probably just aggravated which was already had, she would never have another covid shot or booster again because she had felt so rotten. She had an aching in her shoulders; across the top of the shoulders, it felt like a flu. She was getting concerned about the length of time, the fact that she also weighed like 98lb probably had an effect on that booster too, although when she had covid shot one and two she had no reaction. She said she was not feeling good for a couple of days and would not have any more of this crap.   Follow-up attempts are completed. No further information is expected.
