Great. That's about 300 deaths a day, not 2k.
Right, so can we at least agree that vaccines are already lowering US deaths?
Now, I believe the number is closer to 50% than 10%, for several key reasons.
1) The 17% figure you quoted is only using data from half of the states who report vaccines by age. Realistically speaking, if we assume the proportion of 60+/60- getting vaccines in States that aren't reporting by age is the same as States reporting by age (2:1), we'd be at around 25% of 60+
2) That 25% is of 60+, if you narrow it to LTC I'm guessing you're at 80%+ vaccinated, and 75+ probably 50%+ vaccinated (group is half the size + more prioritization). That's already 66% efficacy after one dose x 60% of deaths 75+ x 50% vaccinated = 20% reduction in deaths (besides for the reduction in under 75)
3) There are 10m people with a second dose and 95%+ efficacy against deaths, again biased towards the highest risk group (LTC residents and staff)
4) The efficacy rate is 66% against infection. Against death, even after one dose, it's likely closer to 85%+.
If you add up the optimistic numbers of 85% efficacy against death + 50% of 75+ vaccinated (60% of deaths) + 25% of 60+ vaccinated (30% of deaths), you get 30%+ reduction in deaths. Now compound that with less spread inside LTC (where staff members were also vaccinated), and between the elderly and their peers, and it's easy to see 50%.
I'm not defending any specific number, I'm arguing that vaccines are definitely reducing US deaths already, and it's not crazy to assume that number is over 1000/day currently.
