Most adults had one MMR shot as children. For most of them, that one shot is enough. NPR reports that certain situations call for a second dose.
That part is settled. It is also dull. The vaccine works. I will not be taking questions about it.
My study looked at the real crisis. On a Saturday, I asked nine adults to find the paper proving they had their first shot. The control group was one more adult, asked to find his car keys. He found them in four minutes.
None of the nine found the paper. Three phoned their mothers. Two found a swimming certificate from primary school instead. One found a photo of himself at six, wearing a cape, and had to sit on the stairs for a while. Another found a warranty for a toaster she no longer owns, and briefly felt hope. My result is what scientists call significant. That means it was not luck. It means it is all of us.
