The other side of the argument…
And, interestingly, if you read the comments to this article, a health care provider notes that measles outbreaks are common in hospitals and urgent care facilities in vaccinated populations, though conveniently diagnosed as ‘viral exanthems.’ Reading the medscape quotation below, one can see that the diagnosis of measles would not be given, by definition, if one has been immunized. In other words, immunization status is used to rule it out and specifically prohibits the diagnosis. Controlling the definitions and stacking the deck in one’s favor…

“An exanthem is any eruptive skin rash that may be associated with fever or other systemic symptoms. Causes include infectious pathogens, medication reaction and, occasionally, a combination of both. Over 100 years ago, a group of characteristic childhood eruptions were described and numbered from one to six:[1,2]measles, scarlet fever, rubella, erythema infectiosum and roseola infantum. The origin of the fourth classic childhood eruption, formerly referred to as Dukes’ disease, is controversial. It may represent misdiagnosed cases of rubella or scarlet fever, rather than a distinct illness.
Viral exanthems are common in childhood. The words ‘exanthema’ and ‘anthos’ mean ‘breaking out’ and ‘flower’ in Greek, respectively. Similarly, a child breaking out with a viral exanthem may be likened to a flower bursting into bloom. In children, exanthems are most often related to infection[3] and, of these, viral infections are the most common. Determining the cause of an exanthem is based on the characteristic morphology, distribution and time course of the eruption, as well as a careful assessment of infectious contacts, immunization status and aspects of the physical examination.”
