Merrry, I have no idea.....I do suppose it may be something in my chart that has just been found through recent testing. I've had a lot of new things added and being tested for so perhaps that has something to do with it? Hope not, but possible. Also, it may have to do with the amount of vcacccine availbe in Florida? At Fl Mayo? I'll see if I can find out anything today when I go. God bless you, Merry and Sundance and desertguy and all. BTW: CA gov is allocating vaccine to prisoners and other outlying groups BEFORE the 65 or 70 +. BEFORE the nursing homes, etc. As is NY. This may surely affect your timeframe. AND, I bet you the availability of vaccine in your state is a factor. Makes sense? Blessings all. Elizabeth
