evidence: In the example, we invented numbers to simplify calculating the death rates. However, the same logic applies to the current COVID-19 pandemic. Comparisons of the absolute numbers, as some headlines do, make a mistake known in statistics as a ‘base rate fallacy’: it ignores that one group is much larger than the other. It is important to avoid this mistake, especially now, as in more and more countries, the number of people vaccinated against COVID-19 is much larger than the number of unvaccinated people (see our vaccination data). [...] This chart presents the COVID-19 death rate among unvaccinated people (0 doses received), people vaccinated without an updated bivalent booster, and those vaccinated with an updated bivalent booster. [...] This chart presents the COVID-19 death rate among people who are not fully vaccinated, among fully vaccinated people, and among those who additionally received a booster dose.
