Key Vault automatically manages Disaster recovery: If you're in a region that automatically replicates your key vault to a secondary region, then in the rare event that an entire Azure region is unavailable, your requests of Azure Key Vault in that region are automatically routed (failed over) to a secondary region. When the primary region is available again, requests are routed back (failed back) to the primary region. Again, you don't need to take any action because this happens automatically. See Microsoft documentation to know more about failover across regions.
