An Inconvenient Study

In October 2025, Del Bigtree’s Informed Consent Action Network (ICAN) released its powerful new film, An Inconvenient Study, about a month after Sen. Ron Johnson held Senate hearings at which the study in question was a central topic of discussion. The large retrospective study showed, unequivocally, that vaccinated children are far more likely to develop chronic disease than their unvaccinated counterparts.

Though the study’s results were dramatic, the real bombshell—the story that made waves at the hearing and which An Inconvenient Study so effectively tells—is one of consequential censorship. When the results came in, demolishing claims of vaccine safety, the investigator who had pledged to publish them “no matter what” reneged on his promise.

The study had its genesis back in 2016, when researcher Marcus Zervos—head of Infectious Diseases at Detroit’s Henry Ford Health—invited Bigtree to dinner as the latter was traveling to promote the movie Vaxxed. Zervos, though staunchly “pro-vax,” had watched Vaxxed and had been stunned to learn that there was no placebo-based trial evidence to establish the safety of childhood vaccines. A couple of years later, Bigtree successfully lobbied Zervos to do a rigorous vax-unvax study using Henry Ford’s exceptionally high-quality data.

As Bigtree has pointed out, An Inconvenient Study—which features hidden-camera footage of the conversation in which Bigtree asks Zervos to explain the study’s non-publication—is fascinating on both a human and big-picture level, illustrating one individual’s internal struggle as well as the larger forces determined to never let the ugly truth about vaccination come to light. Zervos’s personal unwillingness to enter the vaccine fray is especially interesting in light of past actions; not only had he watched Vaxxed and taken it seriously (how many other vaccine champions have been willing to do even that much?), he also had stood up to bullying health authorities at least twice before (criticizing handling of the Flint water crisis and, in 2020, publishing a study favorable to hydroxychloroquine for treatment of Covid).

As for the study, commenting on the criticisms of “bias” with which vaccine proponents are now attempting to tarnish the results, Bigtree says,

“If you’re going to say, ‘This study had a bias,’ it was going to be a bias in favor of the vaccinated…. They set out to prove that the vaccinated were the healthiest. Instead, some of their data [on vaccine harms] are even more damaging and terrifying than … other studies.”

On this Valentine’s Day weekend, one of the best gifts you could give to anyone you love who still believes vaccines are harmless is to sit them down to watch this film.
