It's Zostavax that is the live shingles vaccine. It was discontinued in the US in November 2020, but was still used in Australia till last month (November 2023) when it was discontinued here too. Zostavax caused three deaths in immuno-compromised people (that's us) in Australia between 2017 and 2020. It also caused a treatment resistant type of shingles in some people rather than preventing it. And the health authorities all said it was "safe and effective". No wonder so many of us are cautious about vaccines. Shingrix is the non-live vaccine being recommended now.
