"That’s because forgetting the past has precipitated selective amnesia in our post-measles psyche. Ignoring scientific facts has tragically brought us to a place where some people fail to appreciate the values and utility of some of the most phenomenal tools we have created in our historical war on infectious disease.

Put simply, some people have given up on vaccines."
