The Claim in Context 

Some individuals wrongly assert there is a link between vaccines and autism. Many studies have looked at this and found no link. This research, in many countries, involving thousands of individuals, has spanned multiple decades. Any effort to misrepresent sound, strong science poses a threat to the health of children and does a disservice to our autistic community.   

 

Key Facts 

  • Immunizations work by prompting your immune system to recognize a virus or bacteria, so it will be ready to respond if it encounters it again. Immunizations are important to help children stay healthy, so they can learn, grow and thrive.   
  • Scientific research confirms that vaccines are safe and effective. High rates of immunization stop preventable diseases from spreading through our families, schools and communities. 
  • Studies have repeatedly found no credible link between life-saving childhood vaccines and autism.
  • Autistic children and their families deserve support so that they can thrive. With routine screening, autism can be identified early, when children benefit the most from interventions like speech or occupational therapy, individualized educational plans, and family support.   
  • Misinformation about autistic children and false links to vaccinations does a disservice to them and their families. 

Evidence Snapshot 

Immunizations have dramatically reduced the incidence of vaccine-preventable diseases. The AAP, alongside the Centers for Disease Control and Prevention (CDC), rigorously reviews vaccine safety and effectiveness data. The current U.S. childhood and adolescent immunization schedules are based on research showing when vaccines work the best to support children’s and adolescents’ immune systems.  

Professionals like pediatricians identify autism by carefully reviewing a child’s medical, social, family and developmental histories along with directly observing the child’s behaviors. Autism is often first identified in children between 12 and 24 months. This corresponds to many developmental milestones and temporally corresponds to key childhood vaccines giving some the false impression of a linkage between autism and vaccines. 

Why It Matters

We are all healthier when everyone who can get vaccinated does get vaccinated.  Misleading rumors can spark confusion and worry about vaccines, which could undo the great progress we’ve made in preventing serious childhood diseases. Additionally, scientifically debunked claims about vaccines and autism stigmatizes autistic children, adults, and their families and can impact their ability to access the support and resources they need to live and thrive. 


Experts Say:

“Multiple studies from around the world have found no credible link between autism and vaccines. Continuing to push this false science poses significant risks to public health, particularly during one of the worst measles outbreaks in decades. It is also hurtful to the autistic community and a disservice to the thousands of autistic children and adults living rich, fulfilling lives.”
