Trial to Assess Safety, Tolerability, and Immunogenicity of Influenza Virus Vaccine, Trivalent, Types A & B, Live Cold-Adapted (FluMist) and Measles, Mumps, Rubella, and Varicella Vaccines Administered Concurrently to Healthy Children

Condition(s) targeted: Influenza

Intervention: FluMist (Biological); FluMist (Biological); Placebo (Other)

Phase: Phase 3

Status: Completed

Sponsored by: MedImmune LLC

Official(s) and/or principal investigator(s):
Robert Walker, M.D., Study Director, Affiliation: MedImmune LLC

- To compare immune responses to measles, mumps, rubella, and varicella antigens following

vaccination in children who receive FluMist concurrently with MMRIIÒ and VARIVAXÒ and in children who receive an intranasal placebo mist concurrently with MMRIIÒ and VARIVAXÒ (Group 2 vs. Group 1).

- To compare immune responses to the three strains of influenza (H1N1, H3N2, and B)

following a two dose regimen of FluMist in children who receive the initial FluMist dose concurrently with MMRIIÒ and VARIVAXÒ and in children who receive two doses of FluMist alone (Group 2 vs. Group 3).Secondary:

- To assess the safety and tolerability of concurrent administration of FluMist with

MMRIIÒ and VARIVAXÒ.

Official title: A Randomized, Placebo-Controlled, Trial to Assess Safety, Tolerability, and Immunogenicity of Influenza Virus Vaccine, Trivalent, Types A & B, Live Cold-Adapted (FluMist) and Measles, Mumps, Rubella, (MMRIIÒ) and Varicella (VARIVAXÒ) Vaccines Administered Concurrently to Healthy Children (AV018)

Study design: Prevention, Randomized, Double Blind (Subject, Investigator), Placebo Control, Crossover Assignment, Safety Study

Primary outcome: compare immune responses to measles, mumps, rubella, and varicella antigens following vaccination in children who receive FluMist concurrently with MMRIIÒ and VARIVAXÒ and in children

Secondary outcome: Compare immune responses to the three strains of influenza (H1N1, H3N2, and B) following a two dose regimen of FluMist in children who receive the initial FluMist
