Just a quick clarification, I was not accusing you of being anti-science or anti-vax. I was using that as a short-hand for people the who don't want to get vaccinated, I'm sorry if I gave you the impression that I'm talking about you. Regarding the "reaching only people based on certain educational background" I think choosing a citation about northern Nigeria is quite selective. The assertion that people in Africa are more vaccination skeptical seems to be a gross overgeneralisation and is vaccination acceptance rates vary greatly between countries (not surprising as this is the same in the developed world as well). > I'm not implying anything. I'm saying it explicitly. I'm certainly exaggerating for effect, but I'm saying it explicitly: lots of people in poor countries are fearful of medical professionals. Well your choice of language certainly makes an association to stereotypes of "superstitious primitives" > I don't know why that's surprising -- it's true right here in the USA, as well, and one of the reasons why certain ethnic groups have disproportionately bad medical outcomes. Yes some ethnic groups, would these somehow be more likely to engage with the medical professionals that engage with the control groups, or go to the hospitals while being opposed to the "mysterious doctor-magicians"? Also the modern "health-suspicious" population in the USA (and other developed nations) is primarily composed of well off, well educated socio-economic backgrounds, e.g. just look at where recent measles outbreaks happened.
