Vaccines save millions of lives each year. Yet there are more and more people who are unsure about getting them. Why is that? So far, studies have looked at issues related directly to vaccines. But we think it might be something else. Could it have to do with how people’s minds work? To find out, we asked 356 people different questions about what and how they think, and what they believe. 

What did we discover? People who like to trust their feelings and believe in supernatural things are more likely to be against vaccines. But those who think carefully and have some scientific knowledge generally trust vaccines. It seems the way our minds work can affect what we think about vaccines. This is important to remember when we talk about the importance of vaccines.
