Smallpox was, but the ones listed were not. In fact, measles is on the rise right now due to lack of vaccinations in some areas and travel, leading to increased exposure.
The vaccine question will always be controversial, especially the mandatory nature of some. It is a classic example of balancing personal liberties with public safety. If the MMR vaccine becomes optional for children, you can bet with confidence that there will be a dramatic increase in illnesses.
I have significant reservations regarding RFK Jr, but I don't doubt his passion and commitment. I just hope that he can put aside his strong personal beliefs and utilize evidence-based research to guide him, especially with vaccines. His focus on eradicating ingredients that could be harmful, and/or are designed to stimulate appetite and increase consumption is highly commendable and well overdue.
For those who haven't read it, there is a very interesting and enlightening book about some of this:
