I think the choice is pretty simple. Do your homework and then do what is best for you and your family. My situation is such that I have recieved the original 2 shots of Moderna and 3 Moderna boosters since. Early on I told others what they should do. I was very wrong in doing that. I have been diabetic, I have been overweight, I have had 2 major heart surgeries, I have a history or autoimmune desease on both sides of my family. After doing my research I would not have taken anything other than Moderna, even with all my risk factors.
