The fact is that young people are at very low-risk for covid. If you want to bring vaccine status into it, you get way more ROI vaccinating older groups. We've seen Hospitalizations per capita have go from 5 per 100k/day in Jan 2021 to 3 per 100k a day in December 2021[1] because of lower hospitalization rate's in older groups, not from lower rates in younger groups. Hospitalization is also not that clean of a comparison, since a 35yr old who is discharged after a day is taxing the system way less than someone there for a month.

32% of people 25-39 [2] aren't fully vaccinated, sure it would help some if they were but if you really wanted to solve the problem you'd address the large % of older groups that aren't vaccinated and are contributing to the majority of deaths & strain on the health system.

28% of people 40-49

21% of people 50-64

10% of people 65-74

15% of people 75+
