Mawson et al. 2017 (two papers) – internet survey of homeschoolers recruited from anti-vaccine groups; non-random, self-reported, unverified health outcomes. Retracted by the publisher after criticism.
Hooker & Miller 2020/2021 – analysis of “control group” data also from self-selected surveys; same methodological problems.
Lyons-Weiler & Thomas 2020, 2022 – data from a single pediatric practice run by one of the authors; serious selection bias.
Joy Garner / NVKP surveys – activist-run online surveys with no verification.
Enriquez et al. 2005 – a small cross-sectional study about allergy self-reports, not about overall neurodevelopment.
Large, well-controlled population studies (Denmark, Finland, the U.S. Vaccine Safety Datalink, etc.) comparing vaccinated vs. unvaccinated children show no increase in autism, neurodevelopmental disorders, or overall morbidity attributable to recommended vaccines.
