"So what it seems you are suggesting is there are thousands of cases of Diphtheria going undiagnosed, not receiving the correct medications, and what?"

What are the correct medications? What on earth makes you think I believe early 20th century treatments for diphtheria were sound or that diphtheria is typically fatal?

"Again, are these patients then walking around with the same symptoms, going undiagnosed, not getting second opinions etc etc."

Well yeah.

"You read one thing, and think it must be a conspiracy because they are doing a sound and logical operating procedure."

It is logical *if* you accept the premise that vaccines work. However, you can't use the data that comes from these biased diagnoses to prove vaccines work because that is a circularity. But you actually realise this now don't you? You're very much regretting getting involved in this debate.
