Kristin Cavallari's baby won't be vaccinated. Kristin Cavallari decided not to vaccinate her baby because of concerns that autism and childhood vaccinations are connected. Kristin Cavallari said she and her husband Chicago Bears quarterback Jay Cutler decided not to vaccinate their children.

The 27-year-old former "Hills" star is pregnant with her second child. In a recent appearance on Fox show "The Independents," Kristin Cavallari host Lisa Kennedy Montgomery that she and husband Jay Cutler wouldn't be inoculating their children because the jury's not out on the connection to autism.

Cavallari told The Independents, "we don't vaccinate" because "I've read too many books about autism and the studies."

Former MTV VJ Kennedy, said "Well, my mom vaccinated us and she doesn't have any cases of autism either."

Cavallari answered, "The vaccinations have changed over the years, there's more mercury."

Cavallari said "Well, there is a pediatric group called Homestead, Homestead or Homefirst, now I have pregnancy brain I got them confused - they've never vaccinated any of their children, and they haven't had one case of autism. And now one in 88 boys is autistic, which is a really scary statistic."

She added on Fox & Friends on Friday, March 14 "It is a harsh response. You know, it's not something that I publicly wanted to come out and say. I was in an interview and it came up, and it wasn't what I was expecting. But, you know, listen, to each their own. I understand both sides of it. I've read too many books about autism and there's some scary statistics out there. It's our personal choice, you know, and if you're really concerned about your kid, then get them vaccinated and it shouldn't be a problem."

Kristin Cavallari, 27, has had to deal with backlash from some of the antics she pulled on "Laguna Beach" and "The Hills," and she expected more from this decision.

On March 14, Cavallari told HuffPost Live "Vaccines are not something I wanted to publicly come out and speak on. I sort of got bombarded in this interview and thrown off-guard."

Experts warned about following celebrity advice. Dr. Kenneth Alexander, chief of the section of Pediatric Infectious Diseases at the University of Chicago, said "Any association between vaccines and autism has long been disproved. Her words are dangerous, will result in the under-immunization of children, and an increase in morbidity and mortality due to vaccine preventable diseases."

Cavallari explained "Something is happening, and we can't really ignore that. I choose to believe that I think it's in the vaccines but, again, to each their own and that's where I stand on it."
