200 years ago in Scotland the Ministers of every parish wrote an account of their parish. This formed the basis for the statistical accounts of Scotland that evolved into the census.
The Ministers wrote of the great and the good, and the ordinary folks and their lives. Many of them mentioned the scourge that was smallpox and the ravages it had through their people. But, in amongst those comments, about, "The smallpox took fourteen from the Parish this Autumn, and left ten enfeebled", there are the paragraphs from those who's parishes have been blessed by vaccination, and the unparalleled delight in the words written hundreds of years ago, that none have died, none have been blinded, none have been crippled, orphaned, widowed, left destitute, by smallpox.
"The disease killed an estimated 400,000 Europeans annually during the closing years of the 18th century (including five reigning monarchs) and was responsible for a third of all blindness. Of all those infected, 20–60%—and over 80% of infected children—died from the disease."
If you look for smallpox on Wikipedia there is a photograph of a little girl with smallpox, and it would make you weep.
I have a scar on my arm, as does virtually everyone of my generation. We ought to wear it with incredible pride because that scar means our children have none.
