“Meta-analysis showing that formaldehyde — a known carcinogen and and ingredient in most childhood vaccines — exposure causes reproductive and developmental harm, including spontaneous abortions in pregnancy at low doses. Most studies included are in animals that can have similar drug reactions as humans because human toxicity studies are not ethical.”
Methodological issues and evidence of malfeasance in research purporting to show thimerosal in vaccines is safe.
“There are over 165 studies that have focused on Thimerosal, an organic-mercury (Hg) based compound, used as a preservative in many childhood vaccines, and found it to be harmful. Of these, 16 were conducted to specifically examine the effects of Thimerosal on human infants or children with reported outcomes of death; acrodynia; poisoning; allergic reaction; malformations; auto-immune reaction; Well’s syndrome; developmental delay; and neurodevelopmental disorders, including tics, speech delay, language delay, attention deficit disorder, and autism.”
