Vaccine misinformation¶
False or misleading claims about vaccine safety, efficacy, ingredients, or side effects. Includes conspiracy theories linking vaccines to autism, fertility loss, or tracking devices; claims about accelerated development shortcutting safety; and assertions that natural immunity superior to vaccine-induced immunity. Vaccine misinformation overlaps with but is distinct from vaccine hesitancy (a behavioral/attitudinal phenomenon) — misinformation is the false content; hesitancy is the reluctance to vaccinate despite availability.
The field intensified during COVID-19 pandemic as vaccine rollout became politically polarized and social media platforms amplified unverified claims about novel mRNA technologies.
