Jenny McCarthy still isn't convinced.

Jenny McCarthy still isn't convinced.

The actress still firmly believes that vaccines are to blame for development of autism in children, despite last week's British Medical Journal article about a discredited study linking childhood shots to the developmental disorder.

On a blog she wrote for the Huffington Post, McCarthy asked, "Why does one journalist's accusations against Dr. Wakefield now mean the vaccine-autism debate is over?"

"I know children regress after vaccination because it happened to my own son," she stated. "Why aren't there any tests out there on the safety of how vaccines are administered in the real world, six at a time? Why have only two of the 36 shots our kids receive been looked at for their relationship to autism?"

That article charged that the author of the 1998 study, Dr. Andrew Wakefield, hid the fact that some of the dozen children he described in his research already suffered from developmental problems when they were vaccinated.

The British physician had his medical license revoked last year because of "serious professional misconduct," according to

Wakefield had altered the medical histories of the kids whose stories formed the base of his study, CNN reported.

McCarthy's son Evan, was born in 2002 and diagnosed with autism in 2005. Since then, McCarthy, a self-described "mother warrior" has been highly visible as an advocate for autism awareness.

The former model shows no signs of slowing down in her quest to have childhood vaccines looked at more closely.

"Why do other first world countries give children so many fewer vaccines than we do?" she asked. "Vaccines save lives, but might be harming some children. Is moderation such a terrible idea?"

And, referring to the BMJ story, she added, "Last week, this hoopla made us a little stronger, and even more determined to fight for the truth about what's happening to our kids."

McCarthy, who has written books on Evan's condition, including "Louder Than Words: A Mother's Journey in Healing Autism," has said her son is "healed" from autism.
