Relevant laboratory tests and procedures are available in the appropriate section.  Additional information: Received call from consumer regarding the Pfizer COVID vaccine Booster she had on Saturday. She initially had J&J in Mar2021 and they said it was ok to get Pfizer Booster for COVID. She was a 56 yr old female, and for 5 years, she had not a menstrual cycle. Two days later, and continued at the time of report, she had a period. She was a post menopausal 56 year old women. She did contact her doctor. It also needed to be publicly known that this was happening to women. She knew that there were thousands of women who report this. She had social media. CDC was not putting anything out about potential side effects. She had no cancer, uterine or ovarian issues. Her pap was negative. She did not have personal knowledge of anyone else to report on. There had been conversations in the media that it was a potential side effect. She wanted to know why it was not being listed. She did not wish to provide her address. She said that her weight was between 180-190. She did not wish to provide her primary care provider's contact details. She was already following up with her doctor. She hated when women were disregarded and not taken seriously. Sunday was the day she noticed and was the day after she got the booster. It was still steady, but not heavy. That was another thing that was odd. Because of Fibroids in 2012, she had an embolization surgery and that stopped her menstrual cycle and she not have any for almost 5 years. This was alarming. She received the vaccine at pharmacy. She received this one in the same arm she received J&J. It definitely was in the muscle and stated it was sore and she could not hardly move it. This symptoms needed to be made known to CDC and WHO. They were a lot of reasons including her daughter. They did not want to get the vaccine because of these type things not being listed as side effects. At the very least, Pfizer needed to ask questions with women who had received it. She did not have time to complete remainder of report. She did not provide date or outcome for left arm soreness and hardly being able to move it. She looked for follow up from someone and did not want Pfizer to discount women in the studies for the symptoms she was experiencing. She said that if it happened to her, then it was happening to others.   Follow-up attempts are completed. No further information is expected.
