Anna,
Yes, I did know about naturally caught rubella, & am really happy that my daughter has it even if she has some discomfort. I know that the remedies will help her and that her immune system is stronger for it all.
And it vindicates my (changed) belief in the efficacy of vaccination. The more of Coulter I read (and Tinnus Smits), I feel that I cannot expose my children to the morbific agents that are in vaccines.
I remember going to the Dr in the UK as a child & having an injection for one of the infectious diseases (I know I couldn't sit down for days) & promptly got Measles, Chickenpox & Rubella one after the other!! whatever it was it certainly allowed my immune system to kickstart in a big way
