Measles vaccinations: scientific evidence vs. opinion

Hello there!

We are all sadly aware of the measles outbreak in the United States.  For those of you who are teaching, how do you discuss decision-making based on opinion (or lack of information), as opposed to decision-making based on scientific evidence, epidemiology, and medical reports from reputable sources?  This issue of evidence vs. opinion is apparent in many hot topics: climate change, Ebola, and now vaccinations.  I'd be very interested to hear how you deal with this current issue in your classrooms…..

Cheers, Susan
