That was the very first thing that came to my mind! There was an interview that the Stew Peters show aired but I can't remember the doctor's name or I would include the link but he asked a patient of his who was getting the vaccine anyway if he could draw his blood before and after and he said sure. The results were a little scary in that his blood looked attacked after the vaccine and was depleted. This APPEARS to be what would fix that and deliver a healthy amount of iron to your cells. It looks like in encases a group of iron to maybe be released as needed but I just looked in a couple quick places and I thought that this could fix people's blood. Not 100% sure, of course, but would be wicked cool if it was. Sauce: http://www.chemistry.wustl.edu/~edudev/LabTutorials/Ferritin/Ferritin.html

This one states, "The lower-than-normal serum ferritin levels are seen in iron deficiency...can produce some symptoms as:
shortness of breath, fatigue, dizziness, feeling lightheaded, pale skin, and fast heartbeat. Those sound like some symptoms of covid too! The sauce for that quote: https://www.medicinenet.com/ferritin_blood_test/article.htm Edit: I hope they also come up with a way to genetically change the body back so that it stops constantly making the toxic spike proteins but I'm still hopeful on that.
