The real ethical concerns are what lies beyond just removing nasty inheritable diseases, which is the possibility for designer babies. But also the possibility for weaponizing CRISPR, either to create nasty viruses, or make a gene editing weapon. But beyond all that, it's the worry that a few people get to make a decision that will impact the genes of future generations. And with a gene drive, you could guarantee that all descendants would have the desired modification.
I have to imagine that CRISPR will be weaponized regardless of what the civilian world decides to do with it. When it happens, we'll be better off if we have as much experience with it as possible.
There are substantial ethical issues with vaccination as a general thing; there are specific cases where the facts have supporter a fairly broad (though not universal) consensus on the general best approach, but that doesn't change the fact that there are ethical issues in the area of vaccination.
are you kidding. I know tons of asian parents who want blue eyed babies and would pay thousands for it.
