light vaginal bleeding towards the end of May again I have some vaginal bleeding it was a little bit heavier, I am in 3rd long period, I mean it heavy flow with clotting; This is a spontaneous report from a contactable consumer (patient). This 59-year-old female consumer (patient) reported for herself that she received her second dose of BNT162B2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE, Formulation: Solution for injection, Batch/Lot number: ER8729), via intramuscular, administered in arm on 07Apr2021 (at the age of 59-year-old) as single dose for COVID-19 immunisation. The patient thought that the anatomical site of injection for the first one was the left arm but second one was in the right arm but she could be wrong about that. The patient medical history included diabetic, asthma, thyroid disorder; under active thyroid, obese, sleep apnoea syndrome, overweight, stroke from 2018 to an unknown date (had stroke 3 years ago), tuberculosis, Lyme's disease and COVID-19 from Sep2020 to an unknown date. Concomitant medications included a lot of different medications. The patient previously received her first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE, Lot number: ER8727) on 17Mar2021 (at the age of 59-year-old) as single for COVID-19 immunisation. The patient did not receive prior vaccination within 4 weeks. The patient went through menopause in 2014, that was her last period was May2014. Now 2 weeks after she got the 2nd dose, she have some "light vaginal bleeding towards the end of May again I have some vaginal bleeding it was a little bit heavier, I am in 3rd long period, I mean it heavy flow with clotting". She was not sure that this was related to the vaccine but like she heard stories that this was what they called a rare side effect and she was just not sure so she called to find out if this was accurate information that he have heard, if it was what she could do to stop it. The patient was on a lot of different medications, she did not think any of the medication relate to this. She was on the medication to help with her asthma and diabetes but she have not taken any medications or anything because she started getting her period again its just this is the 3rd month and around in it, its heavy like it was when she was a young kid but she have not taken any medicines to stop it or anything like that. The end of Apr2021 she had light vaginal spotting and the end of May it was a little heavier. Now, since the end of Jun2021, and she does not know why, but she has a full blown period. In 29Jun2021, she woke up with it in the morning. She has heard some things about this and wondered if there if there is information about the Pfizer vaccine that this does happen. She does not know if it's true or rumor, but the way he (previous agent) took all the information she suspects that it was true. She called into her regular primary care physician and awaiting a call back for her Gynecologist because she was too old for that. Her regular primary care physician did say that it could be the vaccine, but she did not really know if it was the vaccine. So far the way that it's being treated, it's possible. She just wants to stop the bleeding because she was too old to be having periods. Agrees to provide report details stating if this will help other people to help stop this. It would be good to know if whether this is real or rumor since she has been hearing things about how it has been affecting women. The patient stated she had a liver biopsy which was ok. But they found something with the right side of her heart, she found about that on Thursday. She had a chest X-ray before the liver biopsy and they found like a spot and they have to give a CAT scan and the CAT scan says that it was remarkable and now ironically, she had a very mild case of COVID back in Sep2020 and they thought that may be the spot was left from that. Anyway, its nothing and she did not have to worry about it. Well that was the another test that she had. She had some blood work, she also recently developed, she got Lyme's disease. Nobody knows how she got it because she was a good quarantiner. The patient reported that like at her age and health problems she have to figure out that she would have been on the respirator but no, she had not even been to the ER. The patient did not receive any treatment because it was no big deal to her until that month. That month, like she said it was a full blown period. So, now she was seeking treatment. So she have not received any, she would see a Gynecologist the next day at 01:30. The patient's whole family was vaccinated. She could be the only one with any sort of the problem. The patient underwent lab tests and procedures which included biopsy liver, blood test both with unknown results, chest x-ray found something with the right side of my heart, found like a spot, computerised tomogram its remarkable and sars-cov-2 antibody test: positive in Sep2020. The outcome of the event was unknown.  Additional information has been requested.
