If only half of America is properly vaccinated, where are the epidemics?

The herd immunity argument has always been inconsistent. On the one hand, the theory goes, people who cannot receive vaccines for whatever reason are protected from the disease through a high level of vaccination in the rest of society. On the other hand, the theory continues, parents who don’t vaccinate their children put the health of wider society at risk. How can a handful of people not getting vaccinated be protected from getting sick, while at the same time being so disease-ridden that they make others sick? This doesn’t make sense.
While herd immunity may not exist, herd mentality most definitely does. Health authorities, media commentators, and schools and their parent–teacher associations waste no opportunity in perpetuating this myth. Proponents have done such a thorough job of convincing the public that a parent who questions it is treated like someone who thinks the earth is flat or believes climate change is a conspiracy. On the contrary: an unprejudiced view of the science about vaccines, and an examination of history, clearly show that the herd immunity theory is—and always has been—flawed.   Learn More http://thehill.com/blogs/congress-blog/healthcare/295562-if-only-half-of-america-is-properly-vaccinated-where-are-the
