In the second wave because hospitalisations went up to a peak of about 40,000 from a media point of view, not a medical one, this is potentially very hard to convince the public. We may be in a position in early March where hospitalisations are below 10,000 and this is seen as a fantastic result and so not worth reporting a short time after that happens. In a similar vein last summer the lowest hospitalisations went was roughly around 1,000. With restrictions and vaccines we should really aim to be going lower than this.
An unpleasant scenario is if things rip and people over 50 realise to their horror that hospitals are filling up in smaller numbers with those of their children and children's friends or having to care for their children with long covid. The risk spread of hospitalisation is very different to that of death. Someone in their 30s is only merely half as likely to be hospitalised as someone aged 50-64 (US CDC), whereas the death comparison is 7.5x more likely to to die for a 50-64 year old. Would society see this as acceptable if it happened?
In the colour charts by age groups in many locations whenever there is a big surge you can see in the case rates that people in their late 60s and early 70s are able to shield to some reasonable extent vs other groups. For obvious reasons. This offers the issue that you want people to be able to do normal things but you've just vaccinated a group that are fairly good at shielding so when things open up you don't necessarily get big wins in drops in transmission vs now. In other age groups there are big wins though. I think group 6 debates are about to kick off, this is going to be much more problematic of who's in it and too many variations vs other groups.
