If that is what it took to prevent severe disease against a strain doing as much damage as Delta then fine, it sucks but is what it would take.
If we are trying to prevent some spread, some of the time with highest immunity levels as well as levels of highest disease combined with the groups highest at risk to all be completely random then we should stay the course.
What's the goal right now? I'm struggling to understand. Policy is once again lagging real world data and when that happens it causes people to lose trust in the system. Then again, if we see yet another big policy shift to keep up with changing circumstance, you will be the first one lined up to try and politically weaponize it.
