You haven't provided any evidence for this or actual numbers, just keep pushing the quarter figure. Are we going for zero ICU admissions now? I'm sure there's a percentage in the flu season that end up there who are in this age group? To be blunt if a number of them lost some weight bit would help rather than expecting rest of us to give up our lives for them they could help themselves? Seems personal responsibility has gone out of the window?
Hard numbers have been posted in this thread, but I'll try to draw the two sets of infromation together. Current ICU occupancy is c. 5000, which with 25% of ICU patients under 50 means that we are talking c. 1200 in ICU beds who are in that age group. That is relative to a typical total ICU bed occupancy at this time of year of under 3000. For reference, the same graph posted by
@Domh245 shows that typical ICU capacity is c.3,500-4,000, and that surge capacity to deal with Covid has brought the total number of ICU beds to just over 6,000, at significant cost to routine ICU work.
We also know that not all patients who would normally receive ICU treatment are able to go into ICU. One statistical effect of vaccinating groups 1-9 will be that Covid illnesses are more concentrated in younger age groups, and therefore that for a given level of cases, the proportion of "young" patients will increase as a proportion of the total. How that will offset declining total incidence of Covid will be interesting, and I have not looked at the numbers of cases by age group. However, given that older and more vulnerable adults are more likely to be shielding or otherwise limiting their risk, it seems plausible to me that total cases may not fall far or fast enough with vaccination alone to reduce the number of patients significantly until vaccination progresses past the priority groups.
That suggests a significant burden on hospitals treating Covid patients, and that care is needed as vaccination levels increase not to leave ICU still struggling for capacity as "lower risk" patients absorb very significant capacity within the system.
