Well unfortunately you do have to deal with a lot of people that are scientifically illiterate, and it might take a while for them to understand. And scientists have to deal with these stubborn people, that say that science is wrong because they listen to someone on the radio saying vaccines are wrong and evil, or something doesn't match their personal experience, so they won't believe it. But the whole point of science is that it's extremely counter-intuitive, and science makes us look at the world in a completely new and different way, that we've never imagined before. It's the so-called "argument from personal incredulity" or "appeal to common-sense".
