You raise an interesting point but consider scarlet fever, for which there is still no vaccine. As with the other infectious diseases, it declined both in mortality AND infection rates, despite lack of vaccine. So it’s absolutely not clear that prevalence of measles etc. would be high ex-vaccine.

Yes, that is true, but there is a difference. Measles is said to have a protective affect, like chicken pox. It somehow is a right of passage for children. Parents reported a maturation effect after these diseases, in most cases, unless there was some nutritional deficiency which would cause adverse affects.
