The WHO has in fact claimed that smallpox has been erradicated due to the vaccine.
It can't even be shown that the vaccine has had any affect whatsoever to the apparent dormency of the disease.
In Japan, during its outbreaks, the smallpox vaccine had been administered to 100% of the population. Yet epidemics were still occurring. It was only when health officials stopped vaccinating that the epidemics subsided.
Japan started compulsory vaccination against smallpox in 1872 and continued it for many years with disastrous results. Smallpox steadily increased each year and in 1892 their records showed 165,774 cases with 29,979 deaths -- all vaccinated. During the same time period Australia had no compulsory vaccination laws. The records showed only three deaths from smallpox over 15 years.In the Philippines between 1917 and 1919, the U.S. government staged a compulsory vaccination campaign which brought on the worst epidemic of smallpox in this island nation's history with 162,503 reported cases and 71,453 deaths -- all vaccinated.
Dr. Charles Nichols of Boston gave this indictment:
In India, according to an official return presented to the British House of Commons by Viscount Morley, there have been, during 30 years, 1877 to 1906, 3,344,325 deaths from smallpox of persons presumably vaccinated, for vaccination is universally enforced in India....In each and every community where vaccination ceases and strict sanitation is substituted, smallpox disappears. There are no exceptions to this.
And here...
A temporary increase in the number of vaccinations always takes place during an epidemic of Small-pox, or when an epidemic is feared; but an examination of the curve of vaccination does not support the statement that it checks the epidemic. On careful inspection it will be seen that on three separate occasions a considerable incease in vaccinations was followed by an increase of Small-pox. Let the reader look at the Diagram, and note that in 1863 there was a very great number of vaccinations, followed in 1864 by an increase in Small-pox mortality.Small Pox vaccinations did not diminish smallpox outbreaks in London/Wales from 1835-1864
We see that the vaccine in fact causes an increase in mortality and infection rates rather than a reduction.
