I wonder if a lot of vaccination fear is because the problems associated with the vaccination are a lot easier to relate to (in a society that doesn't often anymore see outbreaks that do a lot of damage) that the problems vaccines are claimed to cause. Like, we all know an autistic kid, or the idea your kid is getting "injected with mercury" - foreign things in your body could cause death, right? That seems easier to relate to than measles or polio - because we really have no idea what that's actually like anymore.
