The big issue with bacterial resistance to antibiotics is that there's a quite limited number of antibiotics, sometimes ~one that works without terrible side effects, so resistance is a _big_ deal. Vaccines don't work like that, there's an effectively unlimited number of vaccines, because they're tailored to the virus. It's still a problem if a virus mutates around your vaccine, but you're not worse off for trying. I am not a virologist, but it doesn't seem to make common sense to me that we're safer if we let a virus spread and just treat it, instead of vaccinating. The more of the virus that's out there, spreading and multiplying, the greater the opportunity for problematic mutations to develop/spread. That also assumes that there's a good treatment, and sufficient capacity to treat everyone quickly, otherwise there's really not a choice there.
