Negligent homicide is punishable both civilly and criminally in most other situations. Why not in refusing to be vaccinated?
Because it doesn't actually do anything with the problem of there possibly being an outbreak of some disease with the potential for widespread death.
Okay, great, you can hold the one person accountable for not vaccinating their kids liable for the deaths of ten people. Fantastic. Ten people still died.
Our justice system is very much a "If X, then Y" system - but what if your goal is not to deal with X the consequences of X, but to prevent it in the first place?
You could argue the deterrent effect, but if someone is irrational enough to ignore the conclusive logic that vaccines prevent you from getting sick, they're probably not going to be much more convinced by a (low) possibility that they might end up in front of a court and possible face prison. (And that's even if it can be proven beyond a reasonable doubt that the one person not getting vaccinated was the direct cause of the deaths beyond a reasonable doubt)
