@Zardoz @BowsacNoodle @Shadowman311 "Small pox was pretty much not a thing anymore long before the 'vaccine' came out...."
You are so completely ignorant and determined to miss the point it's breathtaking.
The "vaccine" started as a 1796 thing! It killed hundreds of millions of people in the 20th Century, and I was required to get a booster before one trip outside the US in the early 1970s.
And it's gone. That's not "pretty much not a thing," that's "not a thing at all!"
And you're completely ignoring the rinderpest animal disease.
Where the indeed very significant, greatest in the First World (and maybe Second? (Communists)) gains in mortality rates were made from potable water and sanitary sewers or the like, and real public health, is not relevant.
That you didn't even check it out tells us your a tribal NPC parroting what you've been told. You're no better than the other side's extremes.
