Survey Finds One Quarter of Americans Incorrectly Link Vaccines and Tylenol to Autism
A new study of 30,000 adults reveals 25% believe childhood vaccines or pregnancy acetaminophen cause autism, despite overwhelming medical evidence.
POLICY WIRE — Washington, USA — A major new investigation indicates that a significant portion of the American population continues to believe unsubstantiated claims regarding the origins of autism.
In a study involving more than 30,000 adults, over 25% of participants claimed that childhood vaccinations or the use of acetaminophen—commonly known as Tylenol—during pregnancy contribute to thedevelopmental condition. These claims contradict a vast body of scientific evidence.
The data suggests that men, Republicans, and individuals aged 35 to 44 were more likely to hold these views. Additionally, Black and Hispanic adults showed higher rates of belief in these unfounded theories.
High-profile political figures, including President Donald Trump and Robert Kennedy Jr., have historically promoted ideas suggesting a connection between vaccines and autism.
Researchers based in Massachusetts, New York, and New Jersey suggest these results point to a decline in confidence toward established public health authorities. Conversely, those with higher trust in medical and scientific institutions were less likely to believe the false claims.
The team noted that their findings support the idea that beliefs regarding science and medicine are becoming increasingly politicized. They observed that while this politicization began before the COVID-19 pandemic, inconsistent responses from state and federal leaders during the crisis likely worsened the issue.
The pandemic and the subsequent distribution of COVID-19 vaccines are widely linked to an increase in misinformation and hesitancy toward vaccinations.
Interestingly, the study found that social media usage was not correlated with these beliefs. In fact, individuals who spent more time on social media were less likely to endorse the myths.
The researchers hypothesized that social media habits might simply reflect general information-seeking behaviors, suggesting that those who use platforms less may have less access to reliable health resources.
The survey gathered data online from 30,288 adults residing across all 50 states and Washington, D.C.
While autism impacts communication and learning skills, the experience varies significantly for every person.
Diagnosis rates in the United States have climbed in recent decades primarily due to improved screening. According to the non-profit Autism Speaks, approximately one in 45 adults is diagnosed with the condition.
The group identifies several verified risk factors, including genetics, exposure to pesticides or air pollution, birth complications, low weight, advanced parental age, maternal obesity, diabetes, and immune disorders.
Autism Speaks has clarified that there is no evidence proving Tylenol causes autism and maintains that vaccines are not a cause either.
The organization explained that because autism is often diagnosed around the time children receive routine shots, people mistakenly assume a link, though decades of research have proven no such connection exists.
These survey results arrived more than a year after President Trump made unverified claims regarding Tylenol and autism, also linking the condition to the measles, mumps, and rubella vaccine. In-n; the president also signed an executive order in August related to these concerns.
