Again vaccination doesn't prevent infection, it causes the body's own immune system to rise and conquer. And, probably suppress transmission since all of the vectors of transmission (coughing etc) are suppressed or eliminated by the body's response. The latter being the key to suppressing each wave of mutation.
There is serious health, well-being, and economic damage propagated by those that fail to vaccinate, fail to mask, fail to take personal responsibility. For me, where I live, life is almost "normal" despite daily positives recently climbing to 8%. But, I VMP (vax, mask, and take personal responsibility). It's those that don't that disserve society. I would also argue that those that fail to VMP are also the first to wimper and whine about and undermine the imposition of the three strategies, which can all be successful given a societal commitment. However, such a commitment is only as strong as its weakest link. And, its the weak links that are the problem. This really isn't rocket science, but some people seem to believe that they are more special than the whole ... and this cannot be tolerated. Sanctions have to be levied against those that deny reality, deny personal responsibility and propagate harm. Exercising freedom carries the burden of responsibility, culpability and being subject to sanction when damage is done ... classic tort.
From a football perspective (in many ways a microcosm of society in a 90 minute event on a field), is it more advantageous to have a team of XI, or a team eleven "1s", or for that matter a team of X plus 1. Time and again the team of XI tends to be superior in outcomes. Consider the Forest match, we were woefully undone by our weakest links ... and we all recognize who they are ... it's no secret, but Martin doesn't have the balls to recognize and accept that he has made a faulty decision (e.g. Hamer v Benda) and correct. This is a profound failure in leadership and mirroring society as a whole which suffers from a profound failure of leadership with respect to COVID.
A contracted athlete has a personal responsibility to self, to team, to the fan base to VMP and if they have an immediate family to that family, and conversely that family has a personal responsibility to the athlete in creating and sustaining a bubble of limited risk. Pop the bubble and we end up where we are.
