Do Vaccines Cause Autism? Myths vs. Facts

August 21, 2025

The question of whether vaccines cause autism has been widely debated, but scientific evidence is clear: vaccines do not cause autism. This myth began in 1998 when a now-retracted study falsely suggested a link between the MMR (measles, mumps, and rubella) vaccine and autism. Since then, dozens of large-scale studies involving hundreds of thousands of children have confirmed there is no connection between vaccines and autism.


Autism is a developmental condition believed to arise from a combination of genetic and environmental factors, not vaccinations. Despite this, the myth has caused fear among parents, sometimes leading to delayed or skipped vaccinations. Unfortunately, this can increase the risk of preventable diseases, which may pose serious health risks to children and communities.


Parents should feel reassured that vaccines are safe and vital for protecting their child’s health. Children with autism benefit from the same medical protections as their peers, and timely vaccinations play a key role in their well-being.


At Achieve Behavioral Therapy, we support families with accurate information, evidence-based practices, and compassionate care—helping children with autism thrive without fear or misinformation.

Sensory clothing for autism refers to specially designed apparel that addresses sensory sensitivities common in autism spectrum disorder by minimizing irritation and discomfort. These garments use soft fabrics, tagless designs, flat seams, and adaptive closures to reduce sensory overload and increase comfort for individuals with sensory processing differences.  Why Sensory Clothing Matters Many autistic individuals experience heightened sensory responses to touch and texture. Ordinary clothing — with tags, stiff seams, or rough fabrics — can trigger discomfort or distress. Sensory clothing for autism is created to prevent those irritations before they happen, helping people stay calm and participate in daily activities more comfortably. Research shows that repeated touching or stroking of comfortable fabrics can provide soothing sensory input, helping some autistic individuals self-regulate during everyday activities.

Starting Applied Behavior Analysis (ABA) therapy is a significant step for parents of children on the autism spectrum. These individualized sessions are known for building important skills and encouraging independence. As your child’s needs evolve and they make progress, you might begin to wonder when it's the right time to stop ABA therapy. This guide will walk you through the factors to consider, helping you make an informed and confident choice for your family. Understanding ABA Therapy for Children with Autism Applied Behavior Analysis (ABA) therapy is a science-based approach that is highly effective for children with Autism Spectrum Disorder (ASD). It focuses on understanding and changing behavior to teach valuable life skills. The primary goal is to encourage positive behaviors and improve areas like communication and social interaction. This therapy is tailored to each child's unique needs, helping them succeed in many aspects of daily life. By breaking down complex tasks into manageable steps, ABA therapy provides the structured support necessary for meaningful development. What Is ABA Therapy and How Does It Work? Applied Behavior Analysis (ABA) is a therapy rooted in the science of learning and behavior. The therapy process begins with a detailed assessment by a certified behavior analyst (CBA) or an ABA therapist. They create a personalized plan to address specific needs, from communication to self-care skills. A core technique in ABA is positive reinforcement. When your child demonstrates a desired behavior, they receive a reward, which encourages them to repeat that action. This method helps reduce challenging behaviors while systematically teaching new, helpful skills that contribute to your child’s development. So, how do you know if your child is ready to leave ABA therapy? A key indicator is when your child consistently meets their goals and can apply their new skills in different environments without constant prompting. This shows they are internalizing what they've learned and are becoming more independent, signaling that a transition may be appropriate. Common Goals and Outcomes of ABA in the United States ABA therapy aims to help children on the autism spectrum achieve greater independence and confidence in their daily activities. The therapy goals are customized to each child but often center on improving communication, social skills, and self-management. By focusing on these areas, ABA can lead to significant positive changes. The ultimate outcome is to empower your child with the tools they need to navigate the world successfully. This includes everything from participating in classroom activities to forming friendships. As skills are developed, families often notice a decrease in challenging behaviors and an increase in positive social interactions. While ABA is a primary intervention, common alternatives to ABA for children with autism include occupational therapy, speech therapy, and physical therapy. These can complement or follow ABA to address specific sensory, motor, or language needs.
