Clinical Trial Summary

Vaccination is currently the most effective means of controlling influenza and preventing its complications and mortality in persons at risk.

Once a year, a meeting of World Health Organization (WHO) experts takes place, leading to a recommendation on the influenza A and B strains that should be used for the production of vaccine for the coming influenza season. For the strains which do not change from the previous year, the vaccine can be formulated from the old mono bulk from the previous year.

Bulks as old as 12 months may be blended to make trivalent inactivated vaccine (TIV) under the current Canadian and US licenses. This study is conducted to evaluate safety and immunogenicity of Fluviral vaccines made with the aged bulk material compared with the new bulk material. This protocol posting has been updated in order to comply with the FDA Amendment Act, Sept 2007.
