2 claim verifications about vaccines vaccines ×
“Vaccines contain ingredients that are harmful to human health.”
This claim is misleading. While it's true that rare allergic reactions to vaccine excipients (like gelatin or PEG) occur in roughly 1 per million doses, the unqualified statement implies vaccines are broadly dangerous. The overwhelming scientific consensus — including WHO, the CDC, the AAP, and a landmark study of 1.2 million children — confirms that vaccine ingredients like aluminum adjuvants and thimerosal are safe at the doses used, with no causal link to autism, neurological disorders, or systemic harm.
“Vaccines cause autism spectrum disorder in children.”
This claim is false. Decades of research — including WHO's December 2025 review of 31 studies, a Danish study of over 1 million children, and reviews by the National Academies and AAP — consistently find no causal link between vaccines and autism. The original 1998 Wakefield study that sparked this myth was retracted for fraud. A 2025 CDC website update noting causation hasn't been "ruled out" reflects uncertainty, not evidence of causation, and was criticized by the National Academies for lacking context.
