Since the diagnosis of her son, Evan Asher, Jenny McCarthy has singled out autism as her cause. Today, the advocate and her boyfriend, actor Jim Carrey will lead the Green Our Vaccines march and rally in Washington, DC Like many other parents, the celeb mama has been very vocal and firm in her belief that there is a link between autism and vaccinations and continues to campaign for more research. The host-turned-playmate-turned-activist penned, Louder Than Words: A Mother's Journey in Healing Autism, a book about her experience helping her six-year-old to overcome his symptoms.

According to an ABC report:

The Institute of Medicine concluded that 19 major studies, tracking thousands of kids, all show no link between vaccines and autism. Still, thimerosal was removed from essentially all childhood vaccines in 2001 in response to autism fears. But autism rates have continued to rise, leaving many experts to consider the case against thimerosal settled.

I am thankful to parents like Jenny who are drawing attention to this issue, and demanding more research be done. According to the organization, Talk About Curing Autism, one in every 150 children in the United States has autism — a statistic that is too alarming for me, a mother of two young children of vaccination age to ignore.
