chills; fatigue; low grade fever; This is a spontaneous report received from a contactable 79-year-old male consumer (patient). A 79-years-old male patient received first dose of BNT162b2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection, Lot Number: EN9581), via an unspecified route on 17Feb2021 (at the age of 79-years) as 1st dose, single dose in the right arm for covid-19 immunisation. The patient medical history included major radial prostatectomy on 04Feb2021. The patient had no allergies. Concomitant medications were not reported. On unspecified date, the patient experienced reaction of chills and fatigue, low grade fever but in a couple hours that went away which lasted about 7 hours. On 11Mar2021 he got the 2nd dose of the Pfizer vaccine. He was fine. He had no problems until 15Mar20201 (4 days afterwards). He started getting chills, shaking uncontrollably , nausea, fatigue, a little bit of everything. He wouldn't be calling you but this has not subsided. It's been 3 weeks now and He was not feeling well. It ebbs and tides. He been taking a diary. He went to the ER last Monday because He was wheezing in the morning and had shortness of breathe in-between all the other symptoms. They did all kind of blood tests, covid test which was negative, chest x-ray showed bronchitis. Blood work and ultrasound of my bladder. Patient stated that They sent me home with a inhaler, steroid and an antibiotic and every day since then it seems like at night 9, or 10 o'clock I start feeling better and sleep through the night. My fever is 97.7F but about 2, 3 or 4 o'clock my fever ticks up a little and I start to feel lousy, my stomach feels... I feel like I have hot flashes; a feeling of warmth with achiness and lack of appetite. So I take my Tylenol 7 or 8 o'clock at night my temperature is 97.7F. I haven't had 1 good day since. I've been to my doctor, ER, I've talked with the CDC. What information do you have for people who have had long term symptoms/side effects? What am I supposed to do? Someone from Pfizer needs to give me advice. If not I'll go to the news network. I don't feel well. It's directly related. No one has given me relief or help. It's impacting my life. I've been sick every day. Is there someone above you who can tell me what to do? I took their (Pfizer's) vaccine that was recommended. It was your vaccine. Not mine. Someone has to have an answer for me. Unless you want to go and have lawsuit and the news. Just think about it, if you had to go through the symptoms of having the flu everyday... please relay this to someone. If I don't heard back within a week, then I'm going ballistic. It's not going to be pretty. Someone has to get back to me to help. I want someone to tell me that I'm not crazy, I'm not the only experiencing this. There has to be an answer. I took your vaccine. You are responsible. I want to know. I can't be the only one in the whole world who is feeling like this. I've been to the ER and the doctors. I've had every side effects but theirs go away in a few days, but mine hasn't. I need advice... that I'm not nuts... something that will help me get better. I want to feel better. It's effecting my family my life. Doesn't it seem odd? I can't be the only one? Someone has to know something. They (drug companies) like to hide the facts. I am sick because I took a (your vaccine) vaccine. I need someone to get back to me'. He reports he did have major surgery about a week before receiving the first injection of the Pfizer covid-19 vaccine. After the first injection, he reports only have mild reactions that went away. After the second dose of the Pfizer covid-19 vaccine, he has been experiencing an achy feeling, heat throughout the body, shivering, shaking, trouble walking, and some fever. He reports taking Tylenol, and that helps, but he is still having symptoms that come and go and it has been 3 weeks since the second injection of the Pfizer covid-19 vaccine. He reports going to the ER for treatment after the second injection, and a COVID-19 test was negative and they did not find anything else other than the Pfizer covid-19 vaccine that would be causing his symptoms. The difference is this hasn't gone away, its now about 3.5 weeks and he hasn't had a good day since then he has been experiencing chills and fever. It goes away for a couple hours, it goes away till around 9 or 10PM at night, then he is good at night, then in the afternoons around 2PM or so the fever kind of comes back and instead of chills he is getting warm flush, when taking his temperature he notices it ticks up. He is taking Tylenol every 6 hours. Patient stated about Fatigue: Yesterday morning he got a blood test and he did not have a fever he was normal 97F, but he could barely take 10 steps, the fatigue varies, it does not coincide with the fever. Looking back over the 3 weeks, the fatigue is better now. The Only thing he thinks could be relevant, on 04FEB2021 he had a major radial Prostatectomy, he was then discharged the following day, he thinks maybe his body never fully recovered from the procedure, but one ever told him anything. The patient underwent lab tests and procedures which included covid test which was negative, chest x-ray showed bronchitis. The patient took Tylenol (Lot SSA042 Expiry Oct2021) for events. The outcome of the events was unknown.  No follow-up attempts are needed. No further information is expected.
