really aching all over; strange headache at top of eyeballs; IBS quite bad and her intestinal area is her weak point; shortness of breath; chills/chills really bad; felt really hot/get really hot; headache; fatigue/she was so tired she could not do anything.; intestinal issues; This is a spontaneous report from a contactable consumer (patient) via medical information team. A 79-year-old female received second dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, formulation: Solution for injection, Batch/Lot Number: not provided), via an unspecified route of administration on 24Feb2021, as 2nd dose, single dose for covid-19 immunisation. The patient medical history and concomitant medications were not reported. The patient received first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, formulation: Solution for injection, Batch/Lot Number: unknown), via an unspecified route of administration on 03Feb2021, as 1st dose, single dose for covid-19 immunisation. The next day patient woke up and had shortness of breath, chills, felt really hot, headache, fatigue and intestinal issues. After 5 days the side effect disappears but every few weeks the same thing (extreme fatigue, headache and intestinal issues) happened again but much milder. She said that she did not experience these on the first dose. She noted that her cousins had the same problem too. She also stated that she is a very strong person and has a strong immune system but surprised that the side effects are coming back especially with her relatives. She was asking if this is normal and if we had information about recurring side effects, and how long will the vaccine be in her system and how long will the side effects last. She also said that she wanted to report her side effects since she said she heard that it would help in the study. Patient was going to call a while back and she thought no, until she spoke with her cousin who had the same thing she went through. Report 1 of 2. Report 1 is caller reporting on herself. Caller would like to explain side effects after the second vaccine, and symptoms that have been coming back. While providing information, caller stated she was waiting to have cataract surgery and she can not see anything. Caller does not have an appointment yet for it but she needs cataract surgery, it is very hard to see up close. Caller confirms that her vision and cataract issues occurred prior to the vaccine, caller states these were way before. Primary /prescribing physician: Caller stated she did not have any additional information. Caller stated she did not have phone number and then provides it and states she has to use a magnifying glass and (pharmacy name) glasses to see anything. Caller adds she has (company name) Complete. No additional information provided. Caller had her first shot on 03Feb2021 and the second was 24Feb2021. Everything was fine but she woke up the next day with all of the symptoms people talk about, caller states not the shortness of breath, but the other things, that went on for five days. Then it went away. Caller clarifies it was chills really bad, strange headache at top of eyeballs, then she gets really hot, then aching all over - really aching all over. She has irritable bowel syndrome quite bad and her intestinal area was her weak point. It really hit her in that area, she was doubled over. It went on for 5 days and then it went away and everything seemed fine. Then, two and a half weeks went by and the same thing. Caller adds she forgot to mention fatigue, she was so tired she could not do anything. She also had the headache, intestinal problem, the whole thing again. It went away and then came back a couple more times. Caller adds right away she will wake up and know, she will go through the same weird symptoms for a couple days and sleep. Then, it goes away again. It has been several weeks which has been good. She has a first cousin and her sister who live in (place name) and they had their shots pretty close the same time she did. Talking to her cousin, she has gone through the same thing and wanted caller to find out if this is the same. There was a tough spell 4 days after the shot, then she was fine, then the same thing happened again for a couple of days at a time were they can't keep their eyes open because they ache all over, have chills, and then it goes away and then comes back. Caller adds her other cousin had the same shots and she did the same thing she had. Caller asks if this is common or something that comes back? A reaction at the beginning that goes on for 5 days, and then she was concerned she should report this for scientists and doctors. Caller asks if there was any comment if any other people have experienced this. Caller stated it is a good idea if she talks because when she gets these things they hit her so hard. Caller asks is it ever going to stop. It is not as bad as having the actual virus and she was glad she had her shots, absolutely, it is just confusing on why this keeps popping up. Caller added she does not want to complete her report, or complete a report on her cousins. Caller added that it has been the same for them as hers, their last shot was a few days before her second one. They had the exact same thing happen. She did not know if maybe it is in the DNA or something. They still get this annoying thing that will pop up and they just lay down and sleep, then they are cold, then they have a headache. It does not last long, a day or a day and a half. Caller added her and her cousins was wondering was this going to go on forever and why was it not leaving their system or do they have good genes to know it was working well. Caller asked to be transferred medical center if she was going to get an answer, that was the only way she can do it. Caller added if her cousins, the sisters, want to report they can do it. Caller adds that as she said their symptoms was exactly the same. As she mentioned, it is in the family and why are they having this. Caller asked if there is a connection because they are family or is it a fluke. Caller added she knows a lot of people who had no side effects at all. Caller confirms the dates of her vaccines and she stated she has the paperwork she was given. Callers wanted to know if this was a problem that it is popping up and if it happens, she wants to make sure it was not really - caller interrupts sentence. Caller stated she was a mixture of things about details of patient. Caller does not provide e-mail address and states that she does not use her computer or anything because of her cataracts. Outcome of all events was unknown.  Information about Lot/Batch number is requested.
