Recombinant Zoster Vaccine: What It Is, Who Needs It, and How It Works

When you hear recombinant zoster vaccine, a non-live vaccine designed to prevent shingles by using a piece of the virus to trigger a strong immune response. Also known as Shingrix, it is the recommended shingles vaccine for adults 50 and older, replacing the older live vaccine that had lower effectiveness and more restrictions. Unlike the old version, this one doesn’t use the live virus at all.
