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.
Bernard Rimland was an American research psychologist, writer, lecturer, and influential person in the field of developmental disorders. Rimland's first book, Infantile Autism, sparked by the birth of a son who had autism, was instrumental in changing attitudes toward the disorder. Rimland founded and directed two advocacy groups: the Autism Society of America (ASA) and the Autism Research Institute. He promoted several since disproven theories about the causes and treatment of autism, including vaccine denial, facilitated communication, chelation therapy, and false claims of a link between secretin and autism. He also supported the ethically controversial practice of using aversives on autistic children.
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.
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.
A vaccine adverse event (VAE), sometimes referred to as a vaccine injury, is an adverse event believed to have been caused by vaccination. The World Health Organization (WHO) knows VAEs as Adverse Events Following Immunization (AEFI).
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).

Mother Warriors: A Nation of Parents Healing Autism Against All Odds is the fifth book published by New York Times bestselling author, activist and television personality Jenny McCarthy. Her previous book, Louder Than Words, reached #3 on the New York Times bestseller list, and has more than 200,000 hardcovers in print after five printings. Many of McCarthy's assertions within the book, such as that she cured her son's autism and the benefits of chelation are highly disputed within the medical and scientific community, as chelation therapy has been fatal in at least one instance. The foreword was written by her son's pediatrician, Jay Gordon.
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.
Bruce Harold Lipton is an American writer and lecturer whose work has been dismissed by some peers as pseudoscience. By his own admission, Lipton's ideas have not received attention from mainstream science. Lipton has not published original scientific research in a peer-reviewed medical journal in 30 years.
The Autism Science Foundation (ASF) is a non-profit organization that funds evidence-based autism research and supports autism families. The organization was founded in April 2009 by Alison Tepper Singer, a former senior executive of Autism Speaks and the longest-serving public member of the Interagency Autism Coordinating Committee (IACC), and Karen Margulis London, co-founder of the National Alliance for Autism Research. Both Singer and London are parents of autistic children.

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.
Texans for Vaccine Choice (TFVC) is an anti-vaccine Facebook group turned political action committee in Texas which advocates for personal belief exemptions to vaccination requirements, based on "a collection of fake news, half- truths, and conspiracy theories". Andrew Wakefield, the disgraced former medical researcher and originator of the MMR autism hoax, and infectious disease specialist Peter Hotez, both describe TFVC's lobbying as very effective, with the rate of Texas students opting out of at least one vaccine at least doubling in around five years and over 50,000 Texas schoolchildren not being vaccinated.
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.
Children's Health Defense (CHD) is an American 501(c)(3) nonprofit activist group mainly known for anti-vaccine disinformation, and which has been called one of the main sources of misinformation on vaccines. Founded under the name World Mercury Project in 2007, it is chaired by Robert F. Kennedy Jr. The group has been campaigning against various public health programs, such as vaccination and fluoridation of drinking water. The group has been contributing to vaccine hesitancy in the United States, encouraging citizens and legislators to support anti-vaccine regulations and legislation. Arguments against vaccination are contradicted by overwhelming scientific consensus about the safety and effectiveness of vaccines. Its $15-million budget is funded through donations from individuals and affiliate marketing revenues.
Vaccine Choice Canada (VCC) is Canada's main anti-vaccination group. It was founded in the 1980s under the name Vaccination Risk Awareness Network (VRAN) and adopted its current name in 2014. The group has been contributing to vaccine hesitancy in Canada, encouraging citizens to forgo immunization and legislators to support anti-vaccine regulations and legislation.
Misinformation related to immunization and the use of vaccines circulates in mass media and social media in spite of the fact that there is no serious hesitancy or debate within mainstream medical and scientific circles about the benefits of vaccination. Unsubstantiated safety concerns related to vaccines are often presented on the internet as being scientific information. A large proportion of internet sources on the topic are mostly inaccurate which can lead people searching for information to form misconceptions relating to vaccines.
