You're a disingenuous moron.
Sanitation reduced death rates, but vaccines reduced incidence of diseases by preventing infection altogether.
The chart is misleading propaganda: it conflates mortality decline (due to supportive care) with incidence decline (due to vaccines) and cherry-picks examples.
The graph ends around 1970, omitting the massive declines in cases and deaths after vaccines became widespread in the 1970s–1990s.
Without vaccines, these diseases would still cause massive epidemics in industrialised nations, as measles outbreaks in undervaccinated communities have repeatedly shown.
