Turning an anti-vaccine argument on its head: How the Rubella vaccine helps prevent autism

The Measles-Mumps-Rubella Vaccine

The Measles-Mumps-Rubella Vaccine


By Joseph Lachman, Published 11/4/2014

Here is an interesting argument to present to opponents of vaccines: Preventing rubella (also known as German Measles) in pregnant women has saved thousands of children from contracting congenital rubella, which can cause autism.

All too often, scientists and medical experts find themselves having to correct misleading or incorrect statements by celebrities and politicians, such as Jim CarreyRob Schneider, and Michelle Bachmann. However, one argument that has not been widely considered is how vaccines have actually helped prevent hundreds if not thousands of cases of autism.

First of all, Centers for Disease Control data shows how effective the MMR vaccine has been for reducing the number of Rubella cases:

While the disease is not particularly threatening for most adults, it is of higher concern for pregnant women, because of the potential for a fetus to contract rubella during gestation. This can result in a variety of birth defects, including damage to the developing fetal brain.

In 1971, Dr. Stella Chess of the New York University Health Center published a study in the Journal of Autism and Childhood Schizophrenia that analyzed the effects of congenital rubella on 243 children; 10 were found to have autism, with a further 8 showing partial symptoms of autism and so Dr. Chess’s study found a compelling connection between congenital rubella syndrome (CRS) and autism spectrum disorders (ASD). With the modern expanded definition of autism, the number may have actually been underestimated by modern standards.

More recently, Dr. Brynn E Berger, Dr. Ann Marie Navar-Boggan, and Dr. Saad B Omer published a study on BMC Public Health that estimates the number of cases of congenital rubella and autism prevented by vaccination from 2001 to 2010.

Their data show that the Rubella vaccine prevented over 16,000 cases of CSR, and consequently prevented over 1200 cases of ASD.

Furthermore, these are conservative estimates. Using recently expanded criteria for autism, their study shows evidence that over 6000 cases of ASD were prevented thanks to the Rubella vaccine.

Preventative medicine often goes under-appreciated in comparison to curative medicine, when a person fails to become ill, it is difficult to prove whether or not preventative medicine was the thing that saved them. However, through a combination of these sources, we can begin to imagine what our lives would be like without them. Consider raising this point whenever someone tells you to avoid the MMR vaccine.
