Ideally you should build defenses against a broad range of virus families that could become dangerous. Including hantaviruses and coronaviruses. Also, there are synergies as demonstrated by remdesivir: antivirals developed for one virus family might help with other families as well. Many emergent viruses are under close surveillance and animal vaccines are under development. Sometimes that alone makes economic sense already, e.g. when you want to protect expensive race horses from dying. The danger of new viruses will only increase in coming years as we 1. travel far more than we used to, taking viruses with us and 2. go into the environments previously inhabited by wild animals like bats (which are a host for a large number of viurses).
