If vaccines work, then of course unvaccinated persons pose no risk to vaccinated persons at all. The persistent, widespread claim that unvaccinated people “put everyone else at risk” is, therefore, nothing more than absurd fear mongering.

A more specific concern is the claim that the tiny percentage of persons not vaccinated for medical reasons, perhaps along with the larger percentage of vaccinated persons whose vaccines don’t work, are put at risk by those exercising non-medical reasons. This belief is also without merit. It is based on the herd immunity theory, which states that if most of a population is immune, the entire population is protected. The presumed problem is that if too many people opt out of vaccines, the herd immunity effect will be compromised, and those not immune due to medical exemptions or failed vaccines are at risk.
