There are advantages and disadvantages: killed vaccines generally do not give a disease reaction, but may give a weaker immune response and do contain adjuvants. Live vaccines do not contain adjuvant, typically give a better immune response but will usually make the kitten show a small disease response some days after vaccination. And there are differences between brands: one breeder I know has Birmans, they react strongly to Nobivac, which is all live, but not to Purevax which has an inactivated calici-component. My own Bengals and Savannahs get either, and have very mild reactions. I will always choose a live vaccine where it is available because of the adjuvants:I don´t like them! (But they are there for a reason)
Talk to your vet, have him (or her) explain to you why exactly that vaccine is being used and what you can expect.
