@mmascari your math is pretty reckless.
You left out several key components that drastically contrast the current state of the pandemic from a year ago.
You're assuming the cohort of people who are unvaccinated is as proportionally vulnerable as the community was in early 2020. Unequivocally it is not.
80% of the 600,000 who died were over the age of 65.
90% of people over the age of 65 are vaccinated for COVID-19 (at least one shot). An unknown portion of the 10% (estimated at 20%) has immunity from prior infection. So just vaccinating that
one cohort effectively reduces the mortality rate of this virus by almost 80%.
Additionally, 99.9% of people who died from COVID are over the age of 18.
More than 2/3 of those people are vaccinated (at least one shot). And a significant chunk of the unvaccinated have immunity from prior infection.
Finally, re: spread. Herd immunity isn't binary. There is still
widespread immunity in the population. You doubled the number of confirmed cases; in reality evidence suggests its closer to 3x that. Regardless, a virus needs hosts to spread. The R0 of this virus is significantly reduced.
The risk an unvaccinated person faces today in terms of becoming infected is no where near the risk it was a year ago.
So, we can talk about case numbers all day. But if they are decoupled from deaths and hospitalizations (which so far they are), it frankly does not matter.
