I don’t think so.
At a personal level, if you are vaccinated for Covid-19, then infected people are no medical threat to you. It makes no sense to single out unvaccinated spreaders by calling them a threat when all vaccination statuses are equally non-threatening to the vaccinated.
At a social level it may seem things are more complicated. For example, you might assume that unvaccinated people are responsible for keeping the disease alive. The assumption might even be true. But again, if you are vaccinated the living disease poses no medical threat to you. Apart from that, the assumption that unvaccinated people uniquely keep the disease alive is not necessarily true. With Covid-19, as with influenza, vaccinated people can also spread the disease, keeping it alive.
What about the social costs? Sick people cause expenses we all bear in some way, and policies to stop the spread of the virus cause inconveniences for everyone. These social costs are unfair to and unnecessary for the vaccinated. Surely the unvaccinated can be blamed for them, right?
No, not right. If the unvaccinated are not solely responsible for keeping the disease alive then blaming them for the social costs is a mistake. You could try a different version of the mistake by saying, if only the unvaccinated would get vaccinated the social costs would decline more rapidly, but in fact no one knows that to be true with certainty. Because the virus mutates all existing vaccines could become ineffective against new variants.
There is, ultimately, no credible way to describe the unvaccinated as a threat to the vaccinated. It is best to count vaccination as a blessing and avoid the temptation to make the unvaccinated into scapegoats.
