Just to be clear, I agree with your point that there is a difference in vaccinated vs. unvaccinated population (e.g. average age). But when you say "targeted" at the most vulnerable, I'm not sure how true that is. There's a pretty big push to get everyone vaccinated, including populations that have been reluctant to get vaccinated until now.
