Criticism of Sayer Ji: the articles, and what has changed since
Sayer Ji has been criticized by fact-checkers, a university science office, an advocacy group and several news outlets, most of it in 2020 and 2021 around COVID-19 vaccines. Much of that coverage repeated one 2021 report, which Facebook disputed the same year. Since then The Guardian, The Independent and Forbes have added notes to their articles, YouTube has reinstated his channels, and in January 2026 the White House and HHS quoted him on federal nutrition policy. The criticism is listed below in full, with links, so readers can judge it for themselves.

His response, in brief
Most of it traces to one report. Much of the coverage after March 2021 repeated the Disinformation Dozen figures. Facebook disputed them within five months, and outlets that published them have begun saying so.
He is not a doctor and has never claimed to be. GreenMedInfo is an index. It links each study to its original record so readers can check the research themselves rather than take anyone’s word for it, including his.
Disagreement is not disinformation. Questioning public-health policy is a debate, and he has always made his case in public, with sources. Where a source he relied on fails, he says so on his corrections page.
Read both sides. Every critical article is linked above. So is the evidence that followed. Readers can weigh them directly.
