It's much better to bet on the drugs. A vaccine will take years to be fully available (let's not forget we have just two phase 1 studies going, the efficacy is still yet to be determined): drugs, if the current or upcoming trials are successful, probably within the end of the year.

And like the drugs, a vaccine may not be successful at all. What do we do in that case?

This is a problem for the ICUs only because there is no specific treatment. If we can treat it like we can treat other grave diseases, the impact becomes smaller and more manageable.
