You're missing out. Because the 9th edition of Encylopedia Britannica is the last edition before the Rockefellers purchased it, it contains information you will never see in modern publications and encyclopedias.

If I recall correctly, Aaron Russo said something in his documentary Freedom to Fascism about the occult significance of 9/11. As the number 10 represents God, 9/11 means skipping over God.

Interestingly enough, they skipped over to the 11th edition and never published a 10th.

From the article-

It is thus clear that humanized cow-pox might be easily cultivated back to its original type; and, as a matter of fact, it has sometimes been so cultivated back by misadventure, with serious consequences to the vaccinated. The risks of vaccination may be divided into the risks inherent in the cowpox infection and the risks contingent to the puncture of the skin. Of the latter nothing special requires to be said; the former will be discussed under the five heads of (1) erysipelas, (2) jaundice, (3) skin eruptions, (4) vaccinal ulcers, and (5) so-called vaccinal syphilis.

In other words, the Jenner vaccines had the following side effects-

(1) erysipelas (bacterial skin infection)

(2) jaundice

(3) skin eruptions

(4) vaccinal ulcers

(5) so-called vaccinal syphilis

That was always the problem with that set of encyclopedias. It was very wordy.
