Randomized Controlled Trial Multicenter Study
Immunogenicity, safety, and tolerability of two trivalent subunit inactivated influenza vaccines: a phase III, observer-blind, randomized, controlled multicenter study.
The objective of this study was to evaluate and compare the immunogenicity, safety, and tolerability of two influenza subunit vaccines, a primarily European-marketed trivalent vaccine (Agrippal®, Novartis Vaccines), and a predominantly U. S.-marketed control trivalent vaccine (Fluvirin®, Novartis Vaccines), in subjects aged 3-64 y. The immunogenicity of both vaccines was evaluated according to the Center for Biologics Evaluation and Research (CBER) criteria. ⋯ Both vaccines were safe and well-tolerated, and elicited robust immunogenic responses in all age groups, meeting both CBER licensure criteria for all three viral strains after completion of the age-recommended vaccination schedule. These findings support the use of the trivalent subunit influenza vaccines Agrippal and Fluvirin for universal vaccination campaigns on an annual basis. ClinicalTrials.gov: NCT00464672.
