Early on in NY that was as high as 88%. Two factors likely contributed the most to such a high number: a. most were elderly and b. they were treated with early ventilator intervention (and at high pressure settings) as ARDS patients had been treated previously. IIRC, a hospital in Chicago discovered HFNC and other high flow O2 therapies improved survival over mechanical ventilation.
Here is info from a more recent meta-analysis:
Measurements and Results: Sixty-nine studies were included, describing 57,420 adult patients with COVID-19 who received IMV. Overall reported CFR was estimated as 45% (95% confidence interval [CI], 39-52%). Fifty-four of 69 studies stated whether hospital outcomes were available but provided a definitive hospital outcome on only 13,120 (22.8%) of the total IMV patient population. Among studies in which age-stratified CFR was available, pooled CFR estimates ranged from 47.9% (95% CI, 46.4-49.4%) in younger patients (age ≤40 yr) to 84.4% (95% CI, 83.3-85.4%) in older patients (age >80 yr). CFR was also higher in early COVID-19 epicenters. Overall heterogeneity is high (
I2 >90%), with nonsignificant Egger's regression test suggesting no publication bias.

In a quick search I did not find Vaxxed vs Unvaxxed rates of mortality in mechanically ventilated patients. Most everything I've seen still shows unvaccinated people still account for 90-99% of deaths.
Here's what ADPH said 8 days ago:
The message here is that if you are vaccinated you are much less likely to be hospitalized, end up on a ventilator, or to die.
