Prof Peter Hotez MD PhD DSc(hon)onX / Twitter1d ago
Writing garbage in CAPS doesn’t make it true. Not only do we have overwhelming scientific evidence that vaccines don’t cause autism, there’s also the complete lack of plausibility based on what we’ve learned about the >100 autism genes and how they operate in early pregnancy x.com/childrenshd/st…

Analysis Summary
Hotez is correct—the scientific evidence overwhelmingly shows vaccines do not cause autism. Recent WHO analysis of 31 studies through August 2025, plus decades of epidemiological research, have found no causal link. Autism has strong genetic roots involving 100+ genes and appears to originate in early fetal development, before vaccine exposure begins, making a vaccine mechanism biologically implausible.
Claims Analysis (3)
“vaccines don't cause autism”
Multiple major health organizations and peer-reviewed research confirm no causal link.
“overwhelming scientific evidence that vaccines don't cause autism”
WHO 2025 review of 31 studies; CDC, AAP, National Medical Association all confirm no causal link.
“complete lack of plausibility based on >100 autism genes and how they operate in early pregnancy”
Over 100 genes implicated in autism; symptoms present prenatally before vaccine exposure. Biological plausibility argument is sound but phrasing slightly oversimplifies complex gene-environment interactions.
