Vaccines completely eliminated smallpox — the last case was in 1979. In 1952 there were more than 60000 cases of polio in the US with more than 3000 deaths. Then came the vaccination campaign. Today there are zero cases anywhere in the Western Hemisphere, and only a thousand a year in the rest of the world; back in 1988 there were hundreds of thousands of cases before the mass vaccination campaign went worldwide. Measles deaths worldwide have dropped from almost 900,000 a decade ago to under 200,000 today because of a mass vaccination campaign. Unfortunately, some frum Jews have been believing nonsense that people like you put out and we have had the chilul HaShem of kids in frum communities getting measles. Blood will be on your hands if any of those kids die.
