Diagnoses of autism have become more frequent since the 1980s, which has led to various controversies about both the cause of autism and the nature of the diagnoses themselves. Whether autism has mainly a genetic or developmental cause, and the degree of coincidence between autism and intellectual disability, are all matters of current scientific controversy as well as inquiry. There is also more sociopolitical debate as to whether autism should be considered a disability on its own.
Generation Rescue is a nonprofit organization that advocates the scientifically disproven view that autism and related disorders are primarily caused by environmental factors, particularly vaccines. The organization was established in 2005 by Lisa and J.B. Handley. Today, Generation Rescue is known as a platform for Jenny McCarthy's autism related anti-vaccine advocacy.
The 2000 Simpsonwood CDC conference was a two-day meeting convened in June 2000 by the Centers for Disease Control and Prevention (CDC), held at the Simpsonwood Methodist retreat and conference center in Norcross, Georgia. The key event at the conference was the presentation of data from the Vaccine Safety Datalink examining the possibility of a link between the mercury compound thimerosol in vaccines and neurological problems in children who had received those vaccines.
The National Vaccine Information Center (NVIC), founded under the name Dissatisfied Parents Together (DPT) in 1982, is an American 501(c)(3) organization that has been widely criticized as a leading source of fearmongering and misinformation about vaccines. While NVIC describes itself as the "oldest and largest consumer-led organization advocating for the institution of vaccine safety and informed consent protections", it promotes false and misleading information including the discredited claim that vaccines cause autism, and its campaigns portray vaccination as risky, encouraging people to consider "alternatives." In April 2020, the organization was identified as one of the greatest disseminators of COVID-19 misinformation on Facebook.
Bernadine Patricia Healy was an American cardiologist and the first female director of the National Institutes of Health (NIH).
Thiomersal is a mercury compound which is used as a preservative in some vaccines. Anti-vaccination activists promoting the incorrect claim that vaccination causes autism have asserted that the mercury in thiomersal is the cause. There is no scientific evidence to support this claim. The idea that thiomersal in vaccines might have detrimental effects originated with anti-vaccination activists and was sustained by them and especially through the action of plaintiffs' lawyers.
Paul Allan Offit is an American pediatrician specializing in infectious diseases, vaccines, immunology, and virology. He is the co-inventor of a rotavirus vaccine. Offit is the Maurice R. Hilleman Professor of Vaccinology, professor of pediatrics at the Perelman School of Medicine at the University of Pennsylvania, former chief of the Division of Infectious Diseases (1992–2014), and the director of the Vaccine Education Center at the Children's Hospital of Philadelphia.
The Office of Special Masters of the U.S. Court of Federal Claims, popularly known as "vaccine court", administers a no-fault system for litigating vaccine injury claims. These claims against vaccine manufacturers cannot normally be filed in state or federal civil courts, but instead must be heard in the U.S. Court of Federal Claims, sitting without a jury.
Jennifer Ann McCarthy-Wahlberg is an American actress, model, and television personality. She began her career in 1993 as a nude model for Playboy magazine and was later named their Playmate of the Year. McCarthy then had a television and film acting career, beginning as a co-host on the MTV game show Singled Out (1995–1997) and afterwards starring in the eponymous sitcom Jenny (1997–1998), as well as films including BASEketball (1998), Scream 3 (2000), Dirty Love (2005), John Tucker Must Die (2006), and Santa Baby (2006). In 2013, she hosted her own television talk show The Jenny McCarthy Show, and became a co-host of the ABC talk show The View, appearing on the program until 2014. Since 2019, McCarthy has been a judge on the Fox musical competition show The Masked Singer.
Claims of a link between the MMR vaccine and autism have been extensively investigated and found to be false. The link was first suggested in the early 1990s and came to public notice largely as a result of the 1998 Lancet MMR autism fraud, characterised as "perhaps the most damaging medical hoax of the last 100 years". The fraudulent research paper, authored by discredited former doctor Andrew Wakefield and published in The Lancet, falsely claimed the vaccine was linked to colitis and autism spectrum disorders. The paper was retracted in 2010 but is still cited by anti-vaccine activists.
Andrew Jeremy Wakefield is a British fraudster, discredited academic, anti-vaccine activist, and former physician.
Autism's False Prophets: Bad Science, Risky Medicine, and the Search for a Cure is a 2008 book by Paul Offit, a vaccine expert and chief of infectious diseases at Children's Hospital of Philadelphia. The book focuses on the controversy surrounding the now discredited link between vaccines and autism. The scientific consensus is that no convincing scientific evidence supports these claims, and a 2011 journal article described the vaccine-autism connection as "the most damaging medical hoax of the last 100 years".
Autism Speaks Inc. is an American non-profit autism awareness organization and the largest autism research organization in the United States. It sponsors autism research and conducts awareness and outreach activities aimed at families, governments, and the public. It was founded in February 2005 by Bob Wright and his wife Suzanne, a year after their grandson Christian was diagnosed with autism. The same year as its founding, the organization merged with Autism Coalition for Research and Education. It then merged with the National Alliance for Autism Research in 2006 and Cure Autism Now in 2007.
Vijendra Kumar Singh is a neuroimmunologist who formerly held a post at Utah State University, prior to which he was a professor at the University of Michigan. While affiliated with both institutions, he conducted some controversial autism-related research focusing on the potential role of immune system disorders in the etiology of autism. For example, he has testified before a US congressional committee that, in his view, "three quarters of autistic children suffer from an autoimmune disease."
Herman Hugh Fudenberg was an American clinical immunologist and the sole identified member of the Neuro Immuno Therapeutics Research Foundation (NITRF).
In the United States, an alternative vaccination schedule is a vaccination schedule differing from the schedule endorsed by the Advisory Committee on Immunization Practices (ACIP). These schedules may be either written or ad hoc, and have not been tested for their safety or efficacy. Proponents of such schedules aim to reduce the risk of adverse effects they believe to be caused by vaccine components, such as "immune system overload" that is argued to be caused by exposure to multiple antigens. Parents who adopt these schedules tend to do so because they are concerned about the potential risks of vaccination, rather than because they are unaware of the significance of vaccination's benefits. Delayed vaccination schedules have been shown to lead to an increase in breakthrough infections without any benefit in lower side effect profiles.
Vaxxed: From Cover-Up to Catastrophe is a 2016 American pseudoscience propaganda film alleging a cover-up by the Centers for Disease Control and Prevention (CDC) of a purported link between the MMR vaccine and autism. According to Variety, the film "purports to investigate the claims of a senior scientist at the U.S. Centers for Disease Control and Prevention who revealed that the CDC had allegedly manipulated and destroyed data on an important study about autism and the MMR vaccine"; critics derided Vaxxed as an anti-vaccine propaganda film.
The Lancet MMR autism fraud centered on the publication in February 1998 of a fraudulent research paper titled "Ileal-lymphoid-nodular hyperplasia, non-specific colitis, and pervasive developmental disorder in children" in The Lancet. The paper, authored by now discredited and deregistered Andrew Wakefield, and twelve coauthors, falsely claimed causative links between the measles, mumps, and rubella (MMR) vaccine and colitis and between colitis and autism. The fraud was exposed in a lengthy Sunday Times investigation by reporter Brian Deer, resulting in the paper's retraction in February 2010 and Wakefield being struck off the UK medical register three months later. Wakefield reportedly stood to earn up to US$43 million per year selling diagnostic kits for a non-existent syndrome he claimed to have discovered. He also held a patent to a rival vaccine at the time, and he had been employed by a lawyer representing parents in lawsuits against vaccine producers.
Extensive investigation into vaccines and autism has shown that there is no relationship between the two, causal or otherwise, and that vaccine ingredients do not cause autism. Vaccinologist Peter Hotez researched the growth of the false claim and concluded that its spread originated with Andrew Wakefield's fraudulent 1998 paper, with no prior paper supporting a link.
Alison Singer is the president of the Autism Science Foundation (ASF). She has also served on the IACC. She was formerly an executive vice president of Autism Speaks and as a vice president at NBC.
