‘This Question Has Been Asked And Answered’

The warfare over vaccines and autism is heating up yet again. This week, Alison Singer, the executive vice president of communications and awareness at Autism Speaks, one of the nation's leading autism advocacy groups, announced her resignation, citing a difference of opinion over the organization's policy on vaccine research. "Dozens of credible scientific studies have exonerated vaccines as a cause of autism," she wrote in a statement. "I believe we must devote limited funding to more promising avenues of autism research." Singer, who has an 11-year-old daughter with autism, joined the organization when it launched in 2005. Singer praised Autism Speaks and its founders, Bob and Suzanne Wright, but said she could no longer work for a group that supports spending limited resources on vaccine research. Calling Singer's resignation "disappointing and sad," Bob Wright says more authoritative research needs to be conducted on the safety of vaccines given to children under 2. "We all know that autism has genetic causes, but it's highly associated with environmental factors we can't get our hands around," says Wright. "Vaccines fall into that category." NEWSWEEK's Claudia Kalb spoke with Alison Singer about her resignation. Excerpts:

NEWSWEEK: Describe Autism Speaks.
Alison Singer: Autism Speaks is an amazing organization. It has really been a privilege for me to work there. Autism Speaks has raised so much awareness of autism and has supported literally thousands of families around the world. I could not be more proud of Autism Speaks and the work that we've done.

But you disagree with their vaccine position?
In general, I disagree with a policy that says, "Despite what this study shows, more studies should be done." At some point, you have to say, "This question has been asked and answered and it's time to move on." We need to be able to say, "Yes, we are now satisfied that the earth is round."

What do you believe the science shows?
There are more than a dozen studies that show no causal link between the MMR [measles-mumps-rubella] vaccine and autism, and thimerosal [a mercury-containing vaccine preservative] and autism. Over and over, the science has shown no causal link between vaccines and autism. My feeling is that if there was an unlimited pot of money at the NIH [National Institutes of Health] from which to fund autism science then it would be fine to say let's study it more. But we don't have that. We have very limited resources and every dollar we spend looking where we know the answer isn't is a dollar we don't have to spend where we might actually find new answers. In general, yes, more research is always better than less. But again, we have limited dollars to spend and we have to use our limited money wisely in ways that are likely to yield new information for families.

How confident are you in the studies that show no vaccine-autism link?
I've read the studies and I've talked to many doctors. One thing that has been a hugely wonderful part of being at Autism Speaks is that I've been able to consult with the top scientists in the field. We work with the top minds. I think that there's this feeling [among some parents] that the vaccine decision is a choice between, "Do I want to risk measles or do I want to risk autism?" That's not a good characterization. We know for a fact that the measles vaccine reduces the risk of getting measles. One choice is backed by science, one choice isn't.

Where would you like to see the research money go?
I think the genetics work has the potential to point us toward important answers. When we can determine which proteins are associated with various genes we can start to understand the mechanism of action that causes autism. Once you understand the mechanism of action, you can start to look for targeted therapies. I would also focus on prenatal exposures. What is a mom exposed to during pregnancy with regard to hormones or maybe medications or even pesticides? Or what's happening in the environment? During flu season, people are more prone to infections so we should look at the incidence of viral infections, flu, hormonal fluctuations and toxins in the environment for both mother and baby.

How is your daughter doing now?
Jodie has benefited tremendously from applied behavioral analysis therapy. She has learned to have some actual communicative speech. She's able to make her wants and needs known. That's really a breakthrough. For three years, she was in private school that focused intensively on language. She gained enough skills to be in a special class in a public middle school. She's not mainstreamed, but she's able to be in that large environment. So she's making great progress.

What do you think caused your daughter's autism?
Jodie had difficulties from the day she was born. She cried constantly, she had difficulty feeding, difficulty sleeping. She was diagnosed in the first few days as having "failure to thrive." I also have a brother diagnosed with autism. He's 44. My first cousin has a son diagnosed with autism. I strongly believe that there is a genetic component.
