Vaccine Theory
From think.pedia
Vaccine Theory is one of the Theories on the cause of Differentiation. It argues that Different individuals have been created as the result of reactions to vaccinations, which became widespread at the turn of the 20th century.
Most experts dismiss this theory due to a lack of evidence. While Differentiation is far from understood, it seems to be related to an observable genetic mutation. Vaccinations could not cause these mutations. In addition, Different individuals have been observed in populations that never received any vaccinations. Experts argue that the only evidence this theory has is a loose correlation between the timing of vaccinations and the appearance of Different individuals.
