You are a reckless spreader of llies.
Smallpox vanished in the Industrialized world simultaneously with mass vaccinations. More than 150 million living Americans have been vaccinated, yet there have been no new smallpox epidemics in America, and not a single case since 1950. So you lie and claim eradication was due to better hygiene.
Yet, when confronted by the undeniable fact that there are more Third World people living in unsanitary conditions and bad hygiene now than ever before, many of whom have been vaccinated, you dodge the question. You have to, because your crackpot lies can't explain the disappearance of smallpox in the Third World in the last 24 years.
There are plenty of slimy little internet holes into which you can crawl, go find one.
