I am sorry to hear about the struggles that this little girl is going through. I have not read through this entire thread but will offer the information that I can.
It sounds like antibiotics, supportive care and close monitoring are going to be the best to get her through this. A blood transfusion and C-Section will have to be decisions based upon the monitoring of the mother. If the anemia progresses and reaches a certain point, then a transfusion might be likely. I would not jump on one too early as giving a second transfusion can be laden with complications.
As far as the vaccines, it is unfortunate that they were given but may or may not be causing any problems. The difficulty with giving them is 1) the mother is very ill. It is not recommended to vaccinate the sick for a variety of reasons. and 2) she is pregnant.
I would have PCV (Pack Cell volume or HCT hematocrit -either way it is a blood percentage to look at the level of anemia) done regulary as well as a CBC (while this included a PCV it also will look to see if the body is producing young red blood cells and how many and also what the white blood cell count is - is it improving? Do we need to change or add another antibiotic? etc...)
I hope this helps. If you were looking for something more specific, please let me know.
I really do wish you, her and her pups the very best
