Primary Outcome Measures:
  • To assess the immunogenicity of the cell-derived subunit vaccine three weeks after vaccination, by applying the CHMP criteria for immunogenicity. [ Time Frame: 3 weeks ] [ Designated as safety issue: No ]
  • To assess the safety and tolerability of the cell-derived vaccine and compare to an egg-derived influenza vaccine. [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]
  • To assess the safety and tolerability of the cell-derived vaccine following revaccination. [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • To assess the immunogenicity of the cell-derived subunit vaccine three weeks after revaccination, by applying the CHMP criteria for immunogenicity. [ Time Frame: 3 weeks ] [ Designated as safety issue: No ]
  • To assess the long-term immunogenicity (6 months) of the cell-derived subunit vaccine. [ Time Frame: 6 months ] [ Designated as safety issue: No ]

Study Start Date: November 2009
Study Completion Date: April 2011
Primary Completion Date: April 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
15 mcg hemagglutinin (HA) per viral strain; 0.5 mL single dose
Biological: Influenza Vaccine
surface antigen, inactivated, prepared in cell cultures
Active Comparator: 2
15 mcg hemagglutinin (HA) per viral strain; 0.5 mL single dose
Biological: Influenza Vaccine
surface antigen, inactivated, prepared in egg (influvac ®)

Detailed Description:

This current phase II study is to pursue objectives similar to those of the ongoing adult phase II trial, but to expand into the elderly population who are more than 60 years of age. The results of this randomized, double blind, egg derived influenza vaccine (Influvac) - controlled, parallel-trial, in healthy elderly subjects are to be conducted over two consecutive years in multiple centers in Europe. At study initiation 600 subjects will be randomly allocated to receive the cell-derived or egg-derived influenza vaccine. At start of the second year subjects will be randomly re-allocated following stratification based upon the initial drug they were allocated and had received.
