1. A method for making an attenuated live virus having an impaired ability to establish latency, comprising:
introducing a recombinant virus comprising all or a portion of a herpes virus genome into a host cell to produce an amount of the recombinant virus suitable for a vaccine, wherein the recombinant virus genome comprises a promoter for a latency gene or transcript that is altered or modified, and the gene or transcript is expressed from the recombinant virus genome during viral replication; and
recovering the recombinant virus from the host cell.
