Question:

Does a sandbox Vault have pre-released environment? 

Answer:

No, a sandbox Vault does not have a pre-released vault. 

Veeva creates pre-release vaults by copying only the configuration of customers' production vaults. If a customer's vault is not yet live on Veeva Vault, Veeva makes this copy using the customer's sandbox vault.
