I've written previously about Mayim Bialik, an actress previously on the TV show "Blossom" and currently on the "The Big Bang Theory." She has a PhD in neuroscience and is a brand ambassador for Texas Instruments. Sounds great, right?

She's also gone on the record stating that her family is "a non-vaccinating" one, and has promoted anti-vaccine literature on her blog. She apparently remains affiliated with the Holistic Moms Network, which includes anti-vaccine advocates Barbara Loe Fisher and Sherri Tenpenny as members on its advisory board, among others.

Because of the anti-science views she has expressed, and their chance to do real harm, I've noted previously that I'm very uncomfortable with Bialik being used as any kind of an ambassador for science and STEM education. And of course, anti-vaccine advocates have seized on her education and anti-vaccine stance as proof of their own correctness:

Now, she's wondering why people think she's anti-vaccine:

i would like to dispel the rumors about my stance on vaccines. i am not anti-vaccine. my children are vaccinated. there has been so much hysteria and anger about this issue and i hope this clears things up as far as my part.

...which is great, from my point of view. I'd really like to see Bialik advocate for vaccines, as she is firmly in the "crunchy" camp that all too often have a reputation as eschewing vaccines.

So did she really change her mind and her stance? If so, why? Or is she just jumping on the "I'm not anti-vaccine" bandwagon like Jenny McCarthy and others who claim not to be anti-vaccine, but at the same time spew vaccine fear and misinformation? Are her kids fully vaccinated, or did they only have the ones she mentioned previously (such as polio for international travel)? Is she walking back statements that are basically anti-vaccine talking points, and removing her support of anti-vaccine doctors like Bob Sears and Lauren Feder (or her own pediatrician, Jay Gordon)?

I really hope so. But I won't hold my breath, and take her statements that she's "not anti-vaccine" with a big grain of salt. After all, that statement, itself, is often an anti-vaccine talking point.
