So, if COVID killed 10x more people than it did, it would be “deadly” in your view. Interesting.
Approximately 10 times more deaths as COVID from the Spanish flu, although the numbers for that pandemic are only estimates and the range is quite large. Of course, the world was less populated then. And, luckily, the COVID vaccines prevented a lot of potential deaths.
In the USA, about half of the 620,000 deaths could have been prevented if more people were vaccinated. https://globalepidemics.org/vaccinations/
I haven’t seen a study for other places, or worldwide, yet.
