Study to Evaluate Immunogenicity, Safety, and Tolerability of ZOSTAVAX™ Vaccine (Zoster Vaccine Live, V211) Administered Concomitantly Versus Nonconcomitantly With Quadrivalent Influenza Virus Vaccine (Inactivated) in Participants ≥50 Years of Age (V211-062)

Summary

The study evaluated immunogenicity, safety, and tolerability of ZOSTAVAX™ Vaccine (V211) administered concomitantly versus nonconcomitantly with Quadrivalent Influenza Virus vaccine (inactivated) in participants ≥50 years of age. The primary hypotheses tested 1) the noninferiority of concomitant versus nonconcomitant vaccination with regard to Varicella zoster virus (VZV) Geometric Mean Titer (GMT) antibody responses, 2) the acceptability of geometric mean fold rise in VZV antibody response after concomitant vaccination, and 3) the noninferiority of concomitant versus nonconcomitant vaccination with regard to influenza virus strain-specific GMT antibody responses.

Outcome

Met primary endpoint

paper The adjusted VZV antibody GMT ratio (CG/SG) was 0.87 (95%CI: 0.80, 0.95), meeting the prespecified noninferiority criterion. PMID 28830693 ↗

paper The VZV antibody GMFR in the CG was 1.9 (95%CI: 1.76, 2.05), meeting the acceptability criterion. PMID 28830693 ↗

paper The concomitant administration of ZV and IIV4 to adults≥50years of age induced VZV-specific and influenza-specific antibody responses that were comparable to those following administration of either vaccine alone PMID 28830693 ↗
