Based on anecdotal evidence and personal observations, I'm tempted to say that there's less vaccine scepticism in the US than there is in Europe. Mandatory or highly recommended vaccinations for multiple diseases are so deeply ingrained in the US culture that people don't really treat another vaccine as a big deal. To add to this, restrictions imposed by state governments regarding travel between states are nowhere near as ridiculous as those imposed by individual European governments. Of course, Europe still has a long way to go to reach Australia in terms of overkill travel restrictions, but that's not to say that it's a good example of coordination.
