This card is probably outdated and needs to be reviewed/deleted. Added a subnote to extra field in the mean time.
The current shingles vaccine is now 2 doses of recombinant zoster vaccine instead of the old version which was 1 dose of live attenuated zoster vaccine. I haven't seen any uworld questions related to this yet to add more info.
"A live attenuated zoster vaccine was available in the US, but it has been discontinued as of November 2020."
