There is no evidence that the FHA put an autism warning label on vaccinations. However, there has been a long-standing controversy regarding a purported link between vaccines and autism, sparked by a 1998 paper by Andrew Wakefield, which was later retracted due to deliberate image manipulation and unethical conduct. Despite numerous studies refuting any association, some groups continue to propagate this idea, leading to ongoing concerns and debates. The CDC and NIH have addressed these concerns through independent reviews, such as the Immunization Safety Review project, which found no causal relationship between vaccines and autism.

Thimerosal-containing vaccines and autism
Thimerosal is a mercury-based preservative used in vaccines to prevent microbial growth and contamination. It has been used as a preservative in vaccines since the 1930s. While some have expressed concerns about the potential link between thimerosal-containing vaccines and autism, extensive research has failed to establish a causal relationship between the two.
In 1999, the Food and Drug Administration (FDA) recommended removing thimerosal from all childhood vaccines as a precautionary measure. This decision was influenced by concerns raised by groups such as Children's Health Defense, which advocated for ending childhood exposure to mercury. As a result, between 1999 and 2001, thimerosal was removed or significantly reduced in all childhood vaccines, except for some flu vaccines.
Despite the removal of thimerosal from most vaccines, rates of autism continued to increase. Multiple studies have been conducted to investigate the potential link between thimerosal-containing vaccines and autism. The Centers for Disease Control and Prevention (CDC) has conducted or funded nine studies since 2003, all of which found no association between thimerosal-containing vaccines and autism spectrum disorder (ASD). Additionally, the Immunization Safety Review Committee of the Institute of Medicine (IOM) reviewed over 200 scientific studies and concluded in 2004 that there was no causal relationship between thimerosal-containing vaccines and autism.
The hypothesis that thimerosal contributes to the development of autism has been extensively examined, and the evidence consistently shows no causal link. Even with the removal of thimerosal from most vaccines, autism rates have not decreased, which further weakens the argument for a causal relationship. While some anti-vaccine groups continue to raise concerns about thimerosal, the scientific consensus is that it does not increase the risk of autism.
It is important to note that while thimerosal was removed from most childhood vaccines, it is still present in some influenza (flu) vaccines. The CDC and other health organizations emphasize that the benefits of flu vaccination outweigh any potential risks associated with thimerosal exposure. Overall, the weight of scientific evidence strongly suggests that thimerosal-containing vaccines do not cause autism, and the focus of autism research has shifted to other potential genetic and environmental factors.

The MMR vaccine and autism
The claim that the MMR vaccine causes autism was first made by Andrew Wakefield, a British gastroenterologist, in a 1998 paper. The study observed 12 children, eight of whom were reported by their parents to have developed autism after receiving the MMR vaccine. However, the study had no control group or control period, and the cases were not consecutive, i.e., they did not include all the children studied. The paper was eventually retracted by the journal, and Wakefield was found to have engaged in unethical conduct, deliberately falsifying facts for financial gain.
Despite the retraction and the lack of scientific evidence, the possibility that the MMR vaccine may cause autism sparked widespread concern and led to further studies. The CDC conducted a study published in Pediatrics in 2004 that included boys and girls from diverse ethnic backgrounds, including Black children. The findings revealed that vaccination between 24 and 36 months was slightly more common among autistic children, but this association was attributed to immunization requirements for preschool special education programs. A rigorous review by the Institute of Medicine also found no link between the MMR vaccine and autism.
Additionally, the hypothesis shifted to focus on thimerosal, a mercury-based preservative used in some childhood vaccines. Thimerosal was never included in the MMR vaccine, but it was studied separately due to concerns about its potential link to autism. Multiple studies, including nine CDC-funded or conducted investigations, found no relationship between thimerosal-containing vaccines and autism.
The controversy surrounding the MMR vaccine and autism has had significant impacts. Some parents remain hesitant to vaccinate their children, leading to outbreaks or resurgences of measles. Autism advocacy groups have also formed to provide support and seek answers. However, extensive research has consistently refuted a causal relationship between the MMR vaccine and autism.

Autism diagnosis rates
There is no evidence that the FDA put an autism warning label on vaccinations. In fact, the FDA has explicitly stated that there is "no credible evidence linking vaccination to autism or other developmental disorders". This statement was backed up by numerous studies conducted over many years.
The only evidence that supports the claim that the FDA announced vaccines cause autism is a label from a vaccine called Tripedia, which was discontinued in 2011. The label listed autism as one of many “adverse events" that were voluntarily reported by doctors or parents, but it also included a disclaimer that cautioned against establishing a causal relationship. Furthermore, thimerosal, a mercury-based preservative found in trace amounts in Tripedia, has been removed or reduced in all childhood vaccines since 1999, except for some flu vaccines.
Now, to address autism diagnosis rates:
According to the CDC's Autism and Developmental Disabilities Monitoring (ADDM) Network, about 1 in 31 (3.2%) children aged 8 years have been identified with Autism Spectrum Disorder (ASD). ASD is reported across all racial, ethnic, and socioeconomic groups, with boys being about four times more likely to be diagnosed than girls. The median age of the earliest known ASD diagnosis was 47 months, ranging from 36 months in California to 69.5 months in Texas (Laredo).
The cumulative incidence of ASD diagnosis or eligibility by age 48 months was higher among children born in 2018 compared to those born in 2014, with an interruption in the pattern in early 2020 due to the COVID-19 pandemic. Overall, 66.5% of children aged 8 years with ASD had a documented autism test.
In terms of educational outcomes, 74% of autistic students in the US graduate with a diploma, compared to 86% of all students. Vocational rehabilitation services have proven effective, with nearly 60% of autistic individuals in the US becoming employed after receiving such services.

Andrew Wakefield's fraudulent paper
In 1998, Andrew Wakefield, a British gastroenterologist, published a fraudulent paper claiming to have identified a novel form of enterocolitis linked to autism. The paper, published in the British medical journal The Lancet, has since been retracted due to several incorrect elements and ethical violations. Wakefield reportedly stood to earn up to $43 million per year selling test kits, and most of his co-authors withdrew their support for the study's interpretations. The General Medical Council (GMC) conducted an inquiry and found Wakefield guilty of dishonesty, acting against patients' best interests, and mistreating developmentally delayed children.
Wakefield's fraudulent paper has been cited more than a thousand times and has been identified as one of the "biggest lies in history." The paper has been linked to various epidemics and deaths, and researchers have tried to understand why it continues to be cited. One reason may be that the citation software does not always indicate the retracted status of the paper. Additionally, malignant misinformers, including Wakefield and his allies, continue to spread bogus claims.
Wakefield has been a prominent figure in the anti-vaccine movement, and his discredited theory linking vaccines to autism has gained traction. In 2015, he was invited to testify before the Oregon Senate Health Care Committee in opposition to a bill eliminating non-medical exemptions from school immunization laws. However, the meeting was canceled, and Wakefield's plans to testify were denied. Despite the retraction of his paper and the exposure of his fraudulent actions, Wakefield's influence on the anti-vaccine movement persists.

Vaccine safety controversies
Despite claims to the contrary, the FDA has not announced that vaccines cause autism. The only evidence supporting this claim comes from the label of the Tripedia vaccine, which was discontinued in 2011. Autism was listed as one of 11 "adverse events" reported by parents or doctors of children who received the vaccine. However, this does not establish a causal relationship.
In 1998, Andrew Wakefield, a British gastroenterologist, published a fraudulent paper claiming that the measles, mumps, and rubella (MMR) vaccine was linked to autism. The paper was later retracted when the study could not be replicated, and Wakefield was found to have engaged in unethical conduct. Despite this, the idea that vaccines cause autism persists among some groups.
In response to these concerns, the Centers for Disease Control and Prevention (CDC) and the National Institutes of Health (NIH) collaborated with the Institute of Medicine (IOM) to develop the Immunization Safety Review project, which addresses vaccine safety issues. The IOM has examined the hypothesized causal association between the MMR vaccine and autism, as well as thimerosal-containing vaccines and neurodevelopmental disorders. Several large studies have been conducted, and no association has been found between vaccines and autism. The CDC and IOM continue to study the safety of vaccines and provide essential data on autism.
While the exact causes of autism are not fully understood, improved diagnostic practices and increased awareness have contributed to the apparent rise in autism rates. Biological factors, such as parental age, may also play a role. The CDC and autism advocacy groups are committed to helping identify children with autism early on and providing intervention services.
In summary, there is no credible evidence linking vaccination to autism or other developmental disorders. The question has been extensively studied, and vaccines have been shown to be very safe. However, vaccine safety controversies persist, and some public health experts continue to express concern about the potential risks of vaccines.
