I think you and I probably agree on this. When the Disney ‘outbreak’ was fresh I looked up the numbers myself. The death and permanent injury rate from measles in the 10 years prior to there even being a vaccine were VERY low. I don’t recall the numbers exactly, but it was in the fractions of one percent.
1962
No measles vaccine.
4 million got measles that year. 300 died. Less than 1 in ten thousand people who got measles actually were killed by it. Even more interesting was how vastly the flu, heart attacks, car crashes, murders, and cancer, as well as many others outnumbered measles as a cause of death in that year.
