Like Helena, I am caught wondering how these people who are against vaccination can't be thankful that generally, these diseases are no longer a threat -- or shouldn't be. I must wonder if any of these people truly understand just how devastating they are, how horrible they are to watch as they take away the young and the old.
The inoculation for smallpox was not unheard of when I was a child, and my father decreed that myself and my sisters would have the procedure -- he would be pleased, I believe, to know that so many other diseases are also able to be eradicated.
