I am diabetic and covid plays very nasty with diabetics so I was quick to get the vaccines and booster. Diabetics have internal organ imbalances to begin with, the covid spiral is very fast. A normal person would fight off the effects before the spiral of internal organs failing would happen, diabetics are already close to the spiral when they first contact the virus. As many concerts and theme parks as we have been, I have no doubt that I have been in contact with the virus and the vaccine is doing its job.
