evidence: Factually inaccurate: There is no available scientific evidence supporting the claims that COVID-19 vaccines cause blood discoloration or weaken the immune system. A video from naturopath Aaron Lewis circulated on social media in September 2023 claiming that COVID-19 vaccines could be sexually transmitted from a vaccinated person to an unvaccinated one. To support his claim, Lewis showed what was allegedly a micrograph of blood from an unvaccinated person soon after sexual intercourse with a COVID-19-vaccinated individual. Lewis then claimed that the blood started to look like "a vaccinated person’s blood". Among what Lewis considered to be the hallmarks of a vaccinated person’s blood were blood "discoloration" as well as a large amount of the fungus Candida. Lewis then added that "mass level of candida" "means that the white blood cells are non-responsive".
