I haven't looked at other vaccine classes, but what would be the relative risk reduction for something like the measles vaccine? Infinity, maybe, since it's absolute risk reduction is basically 100%.
My main point was to demonstrate that the story of statistics can be skewed based on the message that you want to convey. The CDC clearly wants people to live in fear. Why?
The CDC could calm society's fears and anxiety by concentrating on the incredibly small likelihoods of hospitalization or death in the event that someone is infected with COVID. It doesn't make a lot of sense which leads to conspiracy theories and vaccine hesitancy even for those who truly need it. And the fear porn also leads to unnecessary vaccinations of negligible-risk populations, exposing people - usually young & health - to unnecessary risks.
