GMSgrowsanswered grow question 3 years ago If your a pure blood I would not give my blood away at this point. Our blood will be worth a fortune with all the infected covid 19 gene therapy blood. I would only give blood if it is going to be stored for you and your family. Or if another pure blood needs it. If you took the shot, they don't want your blood for a certain amount of time, until it goes back to near normal, if ever.
