Covid has killed 42 people from age 5-14 in the US according to the CDC, for example. That alone is really not something we should be making huge policy decisions around. It's sad, of course, but it's extremely isolated. All it does is distract us from making good policy decisions.
If I was making policy decisions I'd order vaccine rollout as follows:
Essential workers => 80+ years old => 70+ => 60+ => etc. as we produce and distribute the vaccines.
At some point we might look at the data and say "that's good enough, we can resume normal activities while we work to vaccinate the rest of the population".
