Last year she had that vaccine, and she had no side effects. Her doctor said that there have been reports of this side effect. Her personal opinion is that the vaccine is either contaminated or expired. She called (withheld) and they said the expiration was for next year. Patient stated maybe Pfizer is sending out old vaccines. There was too much bacteria that got into her system or something, that is just common sense. Patient was foggy and kind of still weak. She thinks the weakness came from the diarrhea because she lost so much blood. She was still a little weak and said that she was a little achy, but no longer has a fever. The diarrhea started around 2am on Saturday morning. Yesterday morning on 01Oct2023 was her last bowel movement that was bloody. This morning it seems to be ok, but she had a small stool that was dark, almost black. Patient had a lot of gas. There is a knot that is still hot and kind of feverish where she received the vaccine.
