> Aren't unvaccinated individuals the ones who made this decision?
Yes. And personally, as callous as this is, I give zero shits about COVID deaths of people who choose to not vaccinate, though I feel terrible for their family members that got vaccinated and couldn't convince them to vaccinate because right-wing media has poisoned their minds.
> Or is it that the risk that the unvaccinated pose to the vaccinated are so high that they warrant strong arm solutions?
This question is highly subjective.
The vaccines are very effective at preventing spread, hospitalization, and death, but not 100%. Look at the statistics coming from any major hospital, and you'll see the trend that around 95% of the people hospitalized with COVID are unvaccinated.
The more people are vaccinated, the slower the spread, and the lower total number of breakthrough infections and breakthrough disease (Note: There's a difference between the two!).
Back to your question of if the risk is so high to warrant strong-arm solutions...Currently, I'd say no. But how long until Delta evolves into an even worse form that the current vaccines do nothing for?
