Thank you. The latest Covid Booster is dangerous for seniors. Im 81 and gone through all the things others have who got that shot. (Pfizer). I was fine prior to that. I just want all to know that a lot of other people have suffered these same health issues afterward. I have low iron, low hemoglobin, getting infusions. Weak, dizzy. My doctor (hematologist) visits are off the charts for frequency.
