At ICIM yesterday, I talked about the future of immunity.

My kids will get measles once in their lives and carry immunity from it forever. That's how it worked for my grandparents and for everyone before them who survived an illness the natural way. The vaccinated path looks different. It means going through measles again and again, four, five, six times over a lifetime, because that protection keeps wearing off.

We have a choice here, and it should be treated as one. Catch the illness and come out the other side as a pillar of herd immunity for everyone around you, or take an injection that offers something weaker and requires repeating. I should have the right to choose which one is right for my own children.

If we're actually serious about understanding immunity, here's where I'd start. Run titer tests in the places where measles has shown up, every high school, every elementary school, every church. Find out how many vaccinated people are asymptomatic carriers right now, and find out whether what they're carrying is the wild virus or a vaccine strain. That's a test the CDC has never wanted to run, and it's exactly the question we need answered if we're going to have an honest conversation about the future of immunity.
