Vaccines actually threaten herd immunity

Herd immunity was coined in 1933 by A.W. Hedrich who observed measles outbreaks over the course of thirty years. What he discovered was that if 68% of the population had measles through the natural course of infection, the rest of the community (or herd) was protected. But you see, vaccines aren’t natural and they don’t provide life-time immunity, and even if they did 68% would be the number needed for herd immunity, not 95%. Your (and my) herd immunity was threatened the minute vaccines came on the scene.
