Herpes zoster recurrence, and safety and immunogenicity of the recombinant zoster vaccine in adults aged ≥50 years with a history of herpes zoster: A phase 3, randomized controlled trial

In participants ≥50 years with prior HZ, RZV does not increase HZ recurrence risk. RZV was immunogenic, and safety results were consistent with the vaccine's known safety profile, providing evidence to support RZV use in this population.
