"Using simple mathematical modelling, we have shown that, although risk associated with avoiding vaccination during a virulent pandemic accrues chiefly to those who are unvaccinated, the choice of some individuals to refuse vaccination is likely to affect the health and safety of vaccinated people in a manner disproportionate to the fraction of unvaccinated people in the population. Risk among unvaccinated people cannot be considered self-regarding, and considerations around equity and justice for people who do choose to be vaccinated, as well as those who choose not to be, need to be considered in the formulation of vaccination policy. It is unlikely that SARS-CoV-2 will be eliminated, and our findings will likely be relevant to future seasonal SARS-CoV-2 epidemics or in the face of emerging variants."

And this, children, is why we're all here, and why we're so damn angry/disgusted/upset/homicidal about the anti-vaxxers.
If it affected only them, the AVs, and nobody else, I would say "knock yourselves out!" to the willfully vax resistant, and shed no tears when they inevitably died.
But it doesn't. There are kids under 5, and people who legitimately can't be vaxxed (I know exactly 1), and people whose vaccinations may not be as effective because they're immuno-compromised. And many/most of these people are good and decent folk (or young and innocent) who do not deserve the derision we reserve, rightly IMHO, for those who believe anything their hairdresser's third cousin's stepsister says on FB, but not anyone who spent many, many years studying to become a medical professional.
