Autism and vaccine safety

What is autism?

Autism is not a specific disease. It is a group of brain development disorders known as autism spectrum disorders (ASD).

What causes ASD?

We do not know what causes ASD. There is a strong link to family history.

Why do we hear more about autism now?

The number of people with autism is going up. There are many reasons why this could be. Many more behavioral disorders are being included in what we call ASD. We also are more aware of these disorders.

How early can autism be diagnosed?

Doctors are checking all children for this condition at 18 and 24 months. It is important to diagnose autism early.

How are vaccines and autism connected?

There are rumors that an ingredient in vaccines (shots) can cause autism. Thimerosal is a preservative that was used in several vaccines in the past. But it is now only used in some flu vaccines. Studies have not shown that there is a link.

Why should my child be vaccinated?

There are many diseases that can be prevented by vaccines. Vaccines have worked well in this country and many young parents have not seen any of these diseases. Then they make the mistake of thinking their child does not need to get his or her shots.

For example, there was a recent outbreak of measles in California. A child caught measles in Switzerland and then came back home to California. Eleven children who did not get their measles vaccine caught measles from this child.

Measles is a disease that can be prevented by a vaccine. Up to 20 percent of people who get measles need to be hospitalized.

Do not skip or delay vaccination.

Catching a disease that can be prevented by a vaccine can be very serious for your child.
