Anti-vaccinationists sometimes point to examples of real outbreaks where more than half of those infected had been vaccinated. Surely if most of those infected had been vaccinated then the vaccine isn't much good, right? Wrong. The simulator shows that this is exactly what we expect to find. This is because most of the community is vaccinated, so even though a much lower percentage of those vaccinated become infected, the total number may still be greater. It's a bit of statistical trickery on the anti-vaxxer's part.
