I have three autoimmune diseases. I have had 2 shots of the Moderna. Just in case, what have we got to lose if we do not take the third shot (the booster?) Perhaps we have more to lose if we do not take the booster shot. Why not top it off with this last one. We are going around in circles so I will get on the merry go round and ride the pink horse. Who knows what makes sense? This virus has a mind of it's own. Shame on anyone who plays with these viruses and causes an epidemic such as we are experiencing now. God bless us all.
