I think the word is attenuated, weakened but still kept "alive". As opposed to inactivated like the seasonal flue vaccine.V. Zoster vaccine is stored in fridges because it is lyophilised in order to give it sustained shelf life prior to reconstitution and usage. Human Growth Hormone is a similarly stored vaccine.
It's not actually "living" (live) though mate.
