Because the examples you're giving are clearly ridiculous, even to the layperson. Obviously planes can fly, nobody has ever gotten their soul sucked out by a vacuum cleaner, etc.

Now first let me say I think vaccines are a Very Good Thing, but people have actually been harmed by vaccines: it's extremely rare, and happened more in the past than it does today, but it can happen which makes it much harder to shake peoples' paranoia.

Believing electricity can read your thoughts is clearly crazy, but believing vaccines are harmful can just be a case of not understanding/respecting the probabilities involved.
