I suppose I'm puzzled as to why you wouldn't want to delete it in the first place. What happens to it when it sits in the vault?

The reasons why a antivirus program ask you for delete or vault/quarantine options are:-

1.First its your choice whether "to delete" or "To keep it safe for future"

2.It a safe place where that file cannot do any harm to the system.

3.you can restore back the file ,if you feel that you have accidentally removed an important file.

4.The quarantine items can be submitted to the antivirus company so that they can research on that file for a remedy

If you delete it, it's gone for good. If any programs were associated with that file they may no longer work either. If the infection had been quarantined it could be restored back and that program would then work as it had before. This is mainly used for minimum security threats like minor ads and such not high risk viruses. You can quarantine items first and be sure everything is working ok then go back and delete the quarantined items later.
In most cases anti virus programme repairs the infected file immediately. However, if the virus programme does not have the capability to repair the file at the time the infection is detected, it will ask you if you want to send the infected file to the vault/quarantine or delete. The files sent to vault and quarantined can be repaired or cleaned when the virus programme is updated with the virus list which includes the infected virus. By sending the infected file to virus vault or quarantining, no harm is done to your Computer. However, if you choose to delete the file without know what the function of the file is, it may effect your system
It may be an important file, maybe a document you have been working on for months. If you quarantine it you may be able to use other tools to remove the virus.
If you afford delete it, else put it in vault/quarantine and hope someday programme will remove the virus.
