I don't think it's about education specifically on vaccines on the immune system. I've never been interested in biology. Nor in elementary neither in high school. Actually I pretty much disliked the topic. It was boring, so the information didn't stick and I never liked the process of learning. (Nor did I have to learn anything I was really interested in before going to university. Maybe except for history.) However, since I did learn how science and discovery worked and I always loved systems and understanding how they work, once it became an important topic, I couldn't stop reading up on it and had a lot of a-ha! moments. (Partly because of not learning this in high school, I have to admit.) So not knowing is not the problem. Actually no person on Earth knows everything. Not even the basics. And sometimes, when you listen to people who are in denial, some of them actually do know the basics. (Just think of the antivaxxer doctors...) It's more about not willing to admit the situation. It's also about not knowing what they don't know. Now that's one heck of an important lesson I was taught by my excellent physics teacher in high school. He had this saying "knowledge begins with knowing what you don't know" (or knowing/being aware of your lack of knowledge). Which is likely a way of paraphrasing Socrates. And I see a lot of people are just unaware of this. (Yes, Dunning-Kruger.) More educated and more intelligent people fall for this less often probably, but still some of them do, big time. They'll think that they cannot be wrong exactly because they are smart and are usually right. Or, at least this is how they seem to explain it to themselves. But it's simply a lack of self-reflection and humility and a willingness to accept inconvenient consequences.
