The threat of disease isn't news, yet the constant propaganda against anti-vaxers is. People got exposed to measles in the past and the vast majority were fine. You can only get measles once and the odds of dying of measles is akin to the annual odds of choking to death.
The threat of disease is news when we've reduced the risk of it occurring so much that a great many people have never actually seen a case of it, so effectively 0 risk has suddenly become nonzero for anyone who does not have immunity.
