EXPERT COMMITTEE ON POLIOMYELITIS IST REPORT APRIL 1954
WORLD HEALTH ORGANIZATION TECHNICAL REPORT SERIES NO 81
The principal of the test is that specific protective, or virus neutralizing antibodies, can be measured by adding serum containing them (antibodies) to the virus and then injecting the mixture into a susceptible experimental animal. THE FAILURE OF THE ANIMALS TO DEVELOP THE DISEASE (OR LESIONS”) WHICH IS ACQUIRED BY THE CONTROL ANIMALS RECEIVING VIRUS ALONE, OR VIRUS PLUS A SERUM FREE OF THE ANTIBODY IN QUESTION, IS PROOF OF THE PRESENCE OF NEUTRALIZING ANTIBODIES.
Ten or more brains removed from mice showing signs of experimental infection of the nervous system are ground with sand for 30 minutes. Undiluted rabbit serum are added.
And there you have it. Inject the poison into a susceptible(artificially made weak) animal.
If the animal doesn’t get sick, that is their proof that there were antibodies that protected the animal. And that my friends is your “modern science. Lol it would be funny if they didn’t kill millions with their witchcraft.
