Maximum death rate for all age groups with Moderna, which at least according to these plots provides the lowest death rate, is at 0.8/100_000 in August 2021 for all age groups. Maximum death rate for the unvaccinated of age 12-17 is at 0.17/100_000, for age 18-29 it is 0.76/100_000, also in August 2021. So even unvaccinated younger people (age < 30) are better off than the average vaccinated Joe. The thing is, so far…
Sending mass communication about health with a list of "ifs ands or buts" is incredibly challenging especially for a pandemic level response, so if the communication is simply "get the vaccine" then you're going to get a higher uptick.
I understand your nitpick, but also understand the general population doesn't fully grok this stuff.
EDIT: Lemme also add - the data we're viewing is retrospective. We wouldn't know the effect until now, so of course the message has been "Get the vaccine"
