Herd immunity won't happen. And we don't need to discuss what went wrong. We have an actual situation to deal with, regardless of how we arrived at it.
Where we disagree is who decides to take the risk for whom.
And my clear opinion is that the vaccinated already have the advantage of protection. They (and that includes me) are not to take that as a liberty to free movement and resuming life to the max thereby undeniably spreading the virus around, while others haven't even been given the chance of a jab and are still at high risk.
