I checked. Neil Stone is a real doctor. I thought at first this account was a bot, but nope, it’s real. This is how a profession affixes to one’s head blinkers that keep a man undistracted by obvious questions. That a doctor would ask this question is troubling. So is the fact that, at the time of the screenshot (a few days ago), 60 thousand X users would like his post. In this essay, I review two historical cases that illustrate why asking such a question is so troubling.

The scientific link between smoking and cancer was suspected as early as the 1930s (German researchers observed unusually high lung cancer rates among smokers). Epidemiological studies in the 1950s (for example, by British doctors Richard Doll and Austin Bradford Hill) established the connection between smoking and lung cancer. By the 1964 US Surgeon General’s report, the evidence was overwhelming.
Despite the evidence, the tobacco industry mounted one of the most aggressive denial and disinformation campaigns in modern history. For decades, companies funded research designed to sow doubt, launched public-relations offensives, and even testified under oath that nicotine was not addictive and cigarettes did not cause cancer. This resistance lasted until the 1990s, when lawsuits and landmark settlements finally forced accountability.
Concerns over talcum powder and ovarian cancer began appearing in medical literature in the 1970s, when researchers found talc particles (which naturally contain asbestos, a known carcinogen) embedded in ovarian tumors. The theory was that talc applied in the genital area could travel into the reproductive system and cause inflammation, potentially leading to cancer.
Over the years, epidemiological studies produced mixed results—some showing increased risk, others not. For decades, like the tobacco companies, Johnson & Johnson and other manufacturers denied the risks, emphasizing regulatory reviews that did not classify talc as a proven carcinogen. In this way, corporations hid behind government authority.
Lawsuits in the 2010s brought the issue into public view, with internal documents surfacing that suggested the companies were aware of possible risks but continued marketing talc products as safe. Since then, juries have awarded multi-billion-dollar verdicts against talc producers.
The medical industry is one of the largest sectors of the global economy, larger than automobiles, the military, and oil. Healthcare accounts for nearly 18 percent of US GDP—over $4.5 trillion annually—making it the dominant domestic industry.
Within this industry, the pharmaceutical sector is a massive money maker. Globally, the pharmaceutical industry generates more than $1.5 trillion in annual revenue, with profit margins often exceeding 15–20 percent, among the highest of any major sector. Of that, vaccines generate approximately 10 percent of total revenue—$150 billion dollars annually.
Pharmaceuticals consistently deliver high returns due to patent protections, exclusivity periods, and, with vaccines, immunity from liability. This makes Big Pharma both one of the most profitable and politically powerful industries worldwide.
Reflecting on the two historical examples I have given (and the two others cited in my recent essay The Tactic of Reputational Destruction: The Inquisition of Health Secretary Robert F. Kennedy Jr.), why would anybody with a rational mind think that the medical industry has less of an incentive to lie about the harms their procedures and products they produce than R.J. Reynolds or Johnson & Johnson?
Returning to Dr. Stone’s rhetorical question concerning the link between Tylenol and autism, Tylenol (acetaminophen, or paracetamol outside the US) has indeed been around for quite a while. However, for most of the twentieth century, aspirin was the go-to drug for parents in treating children to treat fever and pain. In the late 1970s–1980s, studies linked aspirin use in children with a condition called Reye’s syndrome. As a result, parents and doctors began avoiding aspirin in children. During the 1980s, Tylenol (and ibuprofen) quickly became the preferred fever and pain reducers for kids. This is what could not occur to Stone because of the blinkers of his profession.
In the 1970s–1980s, prevalence estimates for autism were very low, often 2–5 per 10,000 children. In the 1990s, reported rates began to rise sharply. For example, in the US, prevalence estimates rose from 1 in 2,500 (early 1980s) to about 1 in 500 (mid-1990s). Rates continued to climb in the 2000s. In 2000, the CDC’s Autism and Developmental Disabilities Monitoring (ADDM) Network estimated 1 in 150 US children had autism. By 2008, it was 1 in 88. As of 2023, the CDC reported that about 1 in 36 children in the US is identified with autism.
These alarming numbers were raised at the recent inquisition of Robert F. Kennedy, Jr., before the Senate Finance Committee (discussed in the previously cited essay). Yet Senators, especially on the Democratic side, seemed unconcerned about them. They were focused instead on discrediting Kennedy, demanding his resignation as Secretary of Health and Human Services. Kennedy rightly pointed out that those interrogating him had a vested interest in defending the medical industry. Kennedy’s motivation? Public health.
To be sure, broader diagnostic definitions (especially since the 1990s), greater awareness among parents, educators, and clinicians, and better screening and services that identify more children with this disorder account for some of this rise. But all of it? I have trouble believing that. I’ve been alive for six decades, and I don’t remember seeing the number of autistic kids I see today. My impression is anecdotal, to be sure, but I am hardly the only one with this impression. Obscuring potential environmental inputs with the rhetoric of social construction doesn’t sit well with me.
Nor is Kennedy the first to suggest a link between Tylenol and autism. The earliest explicit scientific suggestion linking the two came from a 2008 study by Stephen Schultz. Schultz raised the idea that regression into autism might not be triggered directly by the MMR vaccine (one of the theories explaining the rise of autism), but rather by acetaminophen administered afterward for fever or pain. The study reported an association between early childhood acetaminophen use and regressive autism.
Since then, a hypothesis has emerged from the broader biochemical and historical evidence: autism diagnoses began sharply rising in the early 1980s, coinciding with a widespread replacement of aspirin with acetaminophen for children, due to warnings about Reye’s syndrome. Perhaps this association is coincidental, but determining whether it is imperative—as imperative as determining whether the MMR vaccine or some other environmental factor is associated with the rise of autism.
Relatedly, Sabine Hazan has argued that mRNA COVID-19 vaccination may be associated with a sharp decline in certain beneficial gut microbes, particularly Bifidobacterium, in some individuals. She has suggested that this disruption could influence immunity and possibly wider health outcomes. You may recall that, similarly, Andrew Wakefield proposed in the late 1990s that the MMR vaccine caused gastrointestinal inflammation that, in turn, triggered autism, linking vaccination to both gut disruption and cognitive disorders.
While the reception of Hazan and Wakefield’s research differs in important ways—Wakefield’s claims allegedly having been discredited (reviews of the case scream this at the reviewer), while Hazan’s are under scrutiny (she is taking quite a risk speaking out)—both place the gut microbiome at the center of a vaccine-related hypothesis, suggesting that changes in intestinal bacteria may underlie broader effects on health and even cognition.
None of these connections should be a priori ruled out, and I am not at all convinced by claims that they have been. All connections should be thoroughly examined—and they haven’t been to my satisfaction. And I am hardly alone in lacking confidence that these matters have been thoroughly interrogated.
It would be naïve in the extreme to suppose that Big Pharma welcomes such an interrogation. There is no difference between the medical industry and any other—for all of them, the bottom line is to generate as much revenue for their stockholders as possible. This is why we don’t trust corporations to do their due diligence in determining whether their products are safe. We must leave that to those who have no stake in the profitability of any industry. And the politicians who protect the stockholder at the expense of the stakeholder to keep the campaign donations and other benefits flowing? They must be called out. The last voices to be discredited and pushed to the margins are the brave men and women who are asking the right questions.
Dr. Stone routinely makes posts like this. Here’s another one.

These viral memes with dramatic imagery crediting vaccines with the disappearance of the iron lung—the negative pressure ventilator—subconsciously work to obscure the actual reason the iron lung is no longer the standard way people struggling to breathe are ventilated: the invention and widespread adoption of the mechanical ventilator. The development of positive pressure ventilators is associated with the decline in iron lung use.
During the COVID pandemic, millions of Americans watched thousands of their countrymen ventilated with no awareness that the reason the iron lung was not used is because technology had changed. The dramatic memes work because of the power of propaganda to put awareness out of mind.
