What’s on your mind this week, Bleeding Heartland readers? This is an open thread: all topics welcome.

Both in the “real world” and on social media, it seems like everyone I know is talking about the controversy over mandatory vaccinations in light of the current measles outbreak. Following up on yesterday’s post about some Republican presidential candidates’ comments, here are more related links:

Over at Iowa Starting Line, Pat Rynard compiles reaction from other GOP presidential hopefuls, including Ben Carson, Bobby Jindal, Marco Rubio, and Ted Cruz. (Scot Walker also issued a strong pro-vaccination statement.) Rynard sees Christie and Paul getting “burned” on an issue they didn’t handle well. I’m not so sure. Social conservatives do not agree with big government imposing its judgment on any aspect of child-rearing. Arguably Christie has no hope with that crowd anyway after signing the New Jersey law that banned gay conversion therapy for teenagers, but Paul has a shot with them.

A nurse-practitioner who survived measles as a child wrote this open letter to parents who aren’t immunizing their children.

I believe it’s a huge mistake to discount anti-vaxxers as “anti-science.” I have encountered hundreds of parents who opt against vaccinating and talked with many of them about why we choose to vaccinate our children. My impression is similar to what German Lopez wrote after interviewing a prominent anti-vaccine activist:

Vaccine skeptics do think they believe in scientific evidence. They can cite dozens of studies and cases. They see themselves as the side in this debate that’s actually following the evidence, while the pro-vaccine side is blindly trusting in authority and ultimately getting taken in by a massive pharmaceutical scam.

I also believe that images and accounts of vaccine-injured children (yes, there are some adverse reactions) evoke such a powerful emotional response that it becomes difficult for many parents to imagine deliberately injecting a vaccine into their child. Statistically, every time you put your baby in a car and drive somewhere, your baby is at greater risk of serious injury than when getting a shot at the doctor. Statistically, the number of lives saved by vaccinating against diseases like HiB and meningitis vastly outnumbers the serious adverse reactions to vaccines. But in all the times I have used those arguments, I don’t think I have ever convinced a single skeptical parent to start vaccinating.

Since the year 2000, a growing number of Iowa families have sought medical or religious exemptions from state vaccination requirements. The Des Moines Register reports that there are no efforts in the Iowa House or Senate to tighten the rules on vaccine exemptions. Governor Terry Branstad is also satisfied with current policy, according to a statement from his office.
