The 'saving face' thing is a total nightmare. They botched developing a reasonable exit strategy, and that botch has now festered over a long period of time. There are a number of ways they could throw together a new form of face saving that gives them a new exit strategy, but I have absolutely no idea whether they will, how quickly, or the detail they come up with to get there.
The likes of the BBC also make occasional reference to the real health concerns that remain, and sometimes looked at the detail of that. Its estimated not to be a trivial problem. I covered this here
#10,861 and in the subsequent post, including a study they linked to from earlier this year. That study was looking at what would happen if there had been a Omicron wave earlier this year if there had been no restrictions, mitigations and large behavioural changes in place at all. So its not what we'd actually expect to see happen because if a situation started to develop where it was actually looking like there would be 5 million hospital admissions, 2.7 million intensive care admissions and 1.6 million deaths then neither the authorities nor the masses would be in full on 'behave completely as normal' mode, they would respond, the psychology of the pandemic would take another turn there.
As the BBC point out, the issue isnt just about who has not had vaccines and how good their vaccines are, its also about a lack of immunity in the population from previous infection. Because the crude version of 'herd immunity' that was touted in countries like the UK went down the shitter, but a more nuanced version is still a factor. For example the likes of
2hats has often posted details of the various studies which have shown that 'hybrid immunity', where a persons immune system has a more effective response to the virus if their history includes both vaccination and infection. And that sort of thing does contribute to the lower magnitude of threat we and many other countries currently face from the virus, but China lacks.
In terms of the lower vaccine uptake rate in older people in China, I wonder about the attitudes of both the authorities and people in general. Do older generations in China generally have less faith in modern medicine and more faith in other approaches for example?
