We have a new generation now, with parents who are hopefully less susceptible to 1990s scare stories.
As I said, there are reasons to believe that the single-vaccine treatment is less effective overall, so pandering wouldn't solve the problem anyway. Additionally, in the UK at least, MMR take-up has been increasing somewhat over the last decade, also supporting the idea that education has had an impact.
I might not have had children in the 1990s, but my parents did (albeit before the 1998 MMR Wakefield lies). So it's not exactly true that I am unaware of the potential emotional impact.
