Not one of the things you listed regarding Somalia was "an imminent property of the object." Every one was a sociological factor. That's exactly what I'm saying. The differences across countries can only be explained through sociological factors, rather than some quality of the vaccine itself.
So is it your idea to limit the spread of misinformation after the fact, and then everything is fine? To say that vaccine denial is reproduced top to bottom, instead of being reproduced by the system of consumers and consumers of such content, abetted by the circumstance of vaccines themselves lending themselves well to paranoid narratives, is a bit shortsighed.
I get that this is a charged topic, but let’s not let the subject or “victim” of misinfo off the hook, as well as all the other relevant factors that can be understood to make it easier to combat antivax.
I didn't say any of that. I cited one case of state sponsored misinformation to demonstrate the effects that misinformation in general can have. I never painted it in terms of "top down" misinformation outside of that one example. Of course, once someone is an antivaxxer they're likely to spread misinformation organically.
The solution is a combination of banning the proliferation of antivax misinformation as far as possible, promoting a better understanding of science through funding education, and through any other methods that are shown to be effective. For example, some doctors have found it helpful to offer a choice between staggering the shots instead of doing them all at once, even though there's really no difference, just to let people feel like they're making a choice. As you mentioned, there's some limited success with addressing people who are hesitant because of a fear of needles. But these little tactics miss the core, underlying reasons why it's happening in the first place, which needs to be addressed on a larger scale.
