https://en.wikipedia.org/wiki/Life_expectancy#/media/File:Life_expectancy_by_world_region,_from_1770_to_2018.svgI hope that link works. It is a chart of life expectancy in various parts of the world from 1770 to the present.
Note that what became the industrialized world began a steep climb in life expectancy around 1865, the end if the US Civil War, when the Industrial Revolution really kicked into high gear. That was primarily due to smallpox vaccination public health campaigns. A bunch of other vaccines came on line mostly in the first half of the 20th century.
Up until the 20th century, for all of human history, death of infants and children was the rule, rather than the exception. If a person made into their 20s, the chances of making it to age 60 and beyond was pretty good. Up until 1900, about 40% of infants and children died. Visit a cemetery that existed in the 1800s or before, and see how many children are buried there.
My 4 grandparents were all born within a few years of 1890. One grandmother had 6 children in the 1910-20 years, 2 of which died in infancy. that's a third. My other grandmother, the Mormon one, had 12 children. two died in infancy, 2 more as you adults. That's a third. They were the first generation when the toll of infant deaths started to collapse to what it is today, and vaccination against childhood diseases is almost totally responsible for it.
Life expectancy went from about 35 to about 65 in the Americas between 1865 and 1965. That is the largest percentage jump in human life expectancy that has ever happened in human history, and is almost centainly the largest jump that will ever happen again, barring a nuclear war or something like that that sends humanity back to square one. I had one grandparent who lived into the 1980s, so that massive jump in life expectancy was during the lifetime of people who were alive within living memory of most of us here. Let that sink in.
BTW, also note that Europe (purple line on top) accelerated life expectancy well beyond the Americas starting in about 1945, when Europe adopted universal health care after WWII. The Americas eventually caught up.
Vaccines are probably the single greatest accomplishment in public health, ever.
My grandmother, the one who made it into her late 90s, had polio, and lost most of the muscle in one arm. My dad had something that might or might not have been polio, that affected one leg. It was during his military training as a machine gunner in WWII, and he got reassigned to a clerical job in the US. That probably saved his life.
I don't even know the symptoms of most childhood diseases. Diphtheria? Hell if I know. I am old enough to remember a few of the childhood diseases that did not yet have vaccines when I was young, most notably polio, and smallpox was still around, but almost eradicated. As someone upthread mentioned, there were lines around the block to get polio vaccine when I was a kid. Polio vaccination was damn near universal.
When I think of how many of my parents' siblings died in childhood (we're not talking distant past - **my** parents) and the enormous change in infant death wrought by vacccines, I look at the anti-vaxxers and am gobsmacked. I wonder what the hell these people are thinking?
Yes, vaccines have side effects, up to and including death in rare cases. Having the actual disease also has the same side effects, and considerably more severe and more frequent. People seem to think the choice is between risking vaccine side effects, or being just fine, parasitically benefitting from the herd immunity provided by everyone else. The real choices are that you are risking the side effects of the actual disease, and also weakening that herd immunity for the entire population.
As long as most people chose to be vaccinated, parasitic protection (benfitting from the risks other people take (immunocompromised people who can't get vaccinated excepted) ) works, though being a parasite is generally not thought highly of.
We are reaching a point where for highly infectious diseases, herd immunity is starting to fail because of the anti-vaxxers. As far as I am concerned, that is unethical, bordering on criminal.
End of rant.
