IDAI: MMR Vaccine Does Not Cause Autism – Facts & Dangers of Myths

A decades-old and thoroughly debunked claim linking the measles, mumps, and rubella (MMR) vaccine to autism continues to circulate, prompting renewed concern from medical experts.

Despite extensive scientific evidence disproving any connection, the myth persists, contributing to vaccine hesitancy and increasing the risk of measles outbreaks. This is particularly concerning as cases of measles are rising globally and in Indonesia.

“If someone still says that MMR causes autism, that’s really outdated,” stated Prof. Dr. Dr. Anggraini Alam, Sp.A, Subsp.IPT (K), Chair of the Indonesian Pediatric Association (IDAI) of West Java, during a recent briefing.

The assertion that the MMR vaccine causes autism originated from a flawed 1998 study that has since been retracted and widely discredited. The research was found to be based on falsified data and unethical practices, and the lead researcher was stripped of his medical license.

Supported by Extensive Research

Dr. Anggraini emphasized that numerous large-scale studies have consistently demonstrated no link between the measles vaccine and autism. She cited research involving millions of participants, including studies with sample sizes ranging from hundreds of thousands to over 23 million individuals.

“All of these studies have shown there is no relationship between the measles vaccine and autism,” she explained. These findings reinforce the safety and efficacy of the MMR vaccine and its lack of association with developmental disorders.

Originating from Invalid Research

The origin of the myth can be traced back to the retracted 1998 study, which was deemed scientifically unsound. Dr. Anggraini noted that the researcher behind the study was found to have engaged in fraudulent practices.

Subsequent, more rigorous research with larger and more diverse populations has consistently refuted the initial claims. The findings from these studies have solidified the scientific consensus that the MMR vaccine is safe and does not cause autism.

The Dangers of Believing the Myth

Dr. Anggraini warned that believing this misinformation can lead individuals to forgo vaccination, leaving them and their communities vulnerable to the serious complications of measles. Measles is not a mild illness and can lead to severe health problems.

“Why get vaccinated when it’s better to get it naturally? But we already know the complications,” Dr. Anggraini said. Measles can cause ear infections, severe diarrhea, and even pneumonia, which can be life-threatening.

Measles Weakens Immunity

In addition to the immediate risks of the infection, measles can also lead to a condition known as immune amnesia, weakening the body’s immune system and increasing susceptibility to other diseases.

“After measles, children become vulnerable to various diseases,” Dr. Anggraini explained. This can result in increased risk of infections like pertussis (whooping cough), diphtheria, and pneumonia.

Pertussis is a highly contagious respiratory infection characterized by severe coughing, particularly dangerous for infants. Diphtheria is a bacterial infection that can cause breathing difficulties and is potentially fatal. Pneumonia is a lung infection that remains a leading cause of death in children.

“Measles is like opening the door for other diseases to enter,” she added.

The Importance of Complete Immunization

Given these risks, Dr. Anggraini stressed the importance of completing measles immunization and staying up-to-date with all recommended vaccinations. She also encouraged increased awareness of immunization, not only for children but also for adults, particularly prospective parents, with a focus on the measles-rubella vaccine.

Complete immunization coverage is crucial for preventing the spread of measles and protecting vulnerable populations. The findings could guide future vaccination strategies and public health initiatives aimed at increasing vaccine confidence and coverage.
