简要总结

This study will evaluate the immunogenicity, safety, and tolerability of VARIVAX® (Varicella Virus Vaccine Live) manufactured with a new passage extension (PE34) process compared with the VARIVAX® 2016 commercial process. The primary hypotheses being tested are that antibody response rate and mean antibody titer induced at 6 weeks after a single vaccination by VARIVAX® PE34 Process are non-inferior to those induced by VARIVAX® 2016 commercial process, and that antibody response rate induced by VARIVAX® PE34 Process is acceptable.

结局指标

主要结局

Percentage of Participants With Varicella Zoster Virus Antibody Levels ≥5 Glycoprotein Enzyme-linked Immunosorbent Assay (gpELISA) Units/mL

时间窗: 6 weeks (43 days) after vaccination 1

The varicella zoster virus (VZV) antibody response rate was defined as the percentage of participants with VZV antibody titer ≥5 glycoprotein enzyme-linked immunosorbent assay (gpELISA) units/mL among participants who were seronegative to VZV (titers \<1.25 gpELISA units/mL) at baseline.

Geometric Mean Titer of VZV Antibodies

时间窗: 6 weeks (43 days) after vaccination 1

The geometric mean titer (GMT) of VZV antibodies after vaccination 1 was assessed. Antibody titers were measured with gpELISA.

  • Percentage of Participants With a ≥4-fold Rise From Baseline in Varicella Zoster Virus Antibody Titers in Participants Initially Seropositive to Varicella Zoster Virus Antibody(Baseline and 6 weeks (~43 days) after vaccination 1)
  • Percentage of Participants Who Discontinued From the Study Due to an Adverse Event(Up to 42 days after vaccination 1 and up to 42 days after vaccination 2)
  • Percentage of Participants With One or More Systemic Adverse Events After Vaccination 2 (Incidence > 0)(Up to 42 days after vaccination 2)
  • Percentage of Participants With One or More Vaccine-Related Serious Adverse Events(Up to ~180 days after vaccination 2)
  • Percentage of Participants With Medically-Attended Adverse Events (Incidence ≥5%)(Up to ~180 days after vaccination 2 (Up to ~285 days))
  • Percentage of Participants With Fever (≥102.2 °F Oral Equivalent)(Up to 42 days after vaccination 1; Up to 42 days after vaccination 2)
  • Percentage of Participants With One or More Adverse Events(Up to 42 days after vaccination 1 and up to 42 days after vaccination 2)
  • Percentage of Participants With One or More Vaccine-Related Adverse Events(Up to 42 days after vaccination 1 and up to 42 days after vaccination 2)
  • Percentage of Participants With One or More Systemic Adverse Events After Vaccination 1 (Incidence ≥ 4)(Up to 42 days after vaccination 1)
  • Percentage of Participants With Solicited Injection-site Erythema, Injection-site Swelling, or Injection-site Pain/Tenderness After Vaccination 1(Up to 5 days after vaccination 1)
