Yes, I have done the math. I also have had measles. The math is clear: by the time the measles vaccine was rolled out in 1963, mortality from measles already had declined from 13.3 per 100K to .2 per 100K.

We effectively became naturally immune, and then undid the decades of humoral immune system progress, by a mass vaccination campaign.
I think you are right. Of course it might be other strands of measles but if you are naturally immune through former sickness, your system adjusts. Vaccine immunity does not. I also read that mothers who had immunity give this to their babies, so that they are protected until about 1 year of age and have their own immune system. That makes the sickness less dangerous, too, I would think.
