Something way bigger than we are currently aware of has always been at play..Hm...what might that BE?
"In the United States (and other countries), historical records show that disease mortality declined nearly 90% before the introduction of the vaccine program and routine vaccination programs — as stated in the Trends in the Health of Americans report.
In fact, some of the most prevalent diseases in the early 1900s — including Tuberculosis (TB), Scarlet Fever and Typhoid — followed the same declines WITHOUT ever having a vaccine program (in the US). These diseases were nearly eradicated in the U.S. without the population being vaccinated for them. (See graph)"
