Because you’re a man of science, and because science stands firm against popular fads and hysterias, I urge you to follow the science and eliminate the booster mandate.
Vaccination is effective at preventing the vaccinated from suffering serious consequences from Covid. (And children naturally are at virtually no risk from Covid.) Therefore, those of your patrons who choose not to be vaccinated personally bear the costs of their choice without imposing any costs on those of your patrons who are vaccinated. So your requirement of vaccination is pointless.
By using general lockdowns, and by treating everyone – including school children – as being equally at risk of suffering from Covid, governments caused resources, attention, and mitigation efforts to be spread too thinly. Far too many resources, attention, and mitigation efforts were spent where they had much smaller impact than they would have had were they instead focused on protecting the most vulnerable.
In a world in which not every human being lives an isolated existence – that is, in our world – each of us incessantly acts in ways that affect strangers without thereby justifying government-imposed restrictions on the great majority of these actions. Therefore, justification of government obstruction of the ordinary affairs of life requires far more than an identification of the prospect of some interpersonal impact.
