Jenny McCarthy says she plans to take legal action following a report claiming she had changed her controversial anti-vaccination stance.

McCarthy is an outspoken advocate for autism research and treatment whose views on vaccination have put her at odds with health experts.

The 41-year old claims that her son's autism was caused by vaccines and she has said she was able to cure her son of the disorder by using alternative treatments, such as dietary changes.

An article published by the entertainment news website Radar Online on Friday reported that McCarthy told Time magazine her son may not have had autism after all, and that she was changing her stance on vaccines.

On Saturday, McCarthy took to Twitter to set the record straight, calling the report "blatantly inaccurate and completely ridiculous."

"Evan was diagnosed with autism by the Autism Evaluation Clinic at the UCLA Neuropsychiatric Hospital and was confirmed by the State of California (through their Regional Center). The implication that I have changed my position, that my child was not initially diagnosed with autism (and instead may suffer from Landau-Kleffner Syndrome), is both irresponsible and inaccurate," McCarthy said in a statement.

'The View' host also pointed out that, while Radar claims the Time magazine article is new, it was actually published nearly four years ago.

And besides, McCarthy claims that she never made certain statements to Time that Radar Online attributed to her.

"Continued misrepresentations, such as these, only serve to open wounds of the many families who are courageously dealing with this disorder," McCarthy wrote, adding that she is "taking every legal measure necessary to set this straight."

The TV personality has described the current vaccine schedule for babies as "too bloated" and says studies must be done to ensure the safety of vaccine ingredients.

Health experts in the U.S. and Canada have said her opinions may be influencing parents not to vaccinate their children, which could lead to troublesome consequences.

Research that suggested a link between vaccines and autism has long since been discredited and retracted, and experts say other studies have failed to prove a connection.
