COVID-19 misinformation
Some of McCullough's public statements contributed to the spread of
COVID-19 misinformation.
[7][4]
McCullough testified before a committee of the
Texas Senate in March 2021, posted to
YouTube by the
Association of American Physicians and Surgeons, in which he made false claims about COVID-19 and COVID-19 vaccines, including that people under 50 years of age and survivors do not need the vaccine and that there is no evidence of
asymptomatic spread of COVID-19.

Posted on the Canadian online video sharing platform
Rumble, McCullough gave an interview in April 2021 to
The New American, the magazine of the right-wing
John Birch Society, in which he advanced
anti-vaccination messaging, including falsely claiming tens of thousands of fatalities attributed to the COVID-19 vaccines.
[46] In May 2021, McCullough gave an interview in which he made claims about COVID-19 and COVID-19 vaccines which were "inaccurate, misleading and/or unsupported by evidence," including that survivors cannot be re-infected and so do not require vaccination and that the vaccines are dangerous.

In an interview on the
Fox News program
Tucker Carlson Tonight in May 2021, McCullough claimed that hydroxychloroquine is effective for treating COVID-19 despite there being no supporting evidence.
[28] McCullough later made appearances on
The Ingraham Angle. During television appearances, McCullough contradicted public health recommendations, including when asked about the aggressive spread of COVID-19 among children, by suggesting that healthy persons under 30 had no need for a vaccine,
[29][47] and when asked about the relative merits of vaccination-induced immunity versus "natural" (survivor) immunity, by disputing the necessity of vaccinations to achieve
herd immunity.
