Excerpt:
“The sharp drop in the ID fraction between birth year 2000 and 2002 coincided with the removal of thimerosal, a mercury-containing preservative and neurotoxin linked to autism severity, from most childhood vaccines. Conversely, the renewed increase in the ID fraction after 2006 coincided with the reintroduction of thimerosal via flu shots promoted for infants and pregnant women. Low-income women and children are particularly likely to receive those products in some states, due to health insurance and daycare requirements, which may be contributing to autism severity as well as to the recent strong divergence in ASD prevalence by race/ethnicity.”
