hundreds of thousands got sick

An estimated 7 million deaths since 2020. About 250 deaths a week in the US on an ongoing basis. And that is just deaths, not serious sickness or long term consequences after being sick.

who knows how many survived because they were vaccinated.

We dont know, but we can estimate. COVID-19 vaccinations averted between 1.4 to 4 million deaths during 2020-2024.
