The narrative is breaking down. But why?

It seems that what we've known all along is finally being admitted by the leftist rulers. Why are they now starting to admit that cloth masks are not working. That the vax isn't working. That the hospitals are not full of unvaxed. That children don't need to be masked or healthcare workers can come to work sick. That it's now 5 days instead of 10 for isolation.??
What is happening here.
