Influenza

Brief summary

Occurrence of solicited local and systemic AEs for 7 days after vaccination., Occurrence of unsolicited AEs for 28 days after vaccination., Occurrence of serious adverse events (SAEs), potential immune mediated disorders (pIMDs) and adverse events of special interest (AESIs) for 180 days after vaccination., Occurrence of clinically abnormal hematology and serum biochemistry laboratory values at 7 days, 28 days and 180 days after vaccination versus baseline (Day 1, pre-vaccination).

Detailed description

Immunogenicity of TETRALITE with different adjuvant dose levels as determined by: The HI antibody titers in serum samples against the 4 vaccine influenza strains at 7 days, 28 days and 180 days after vaccination versus baseline (Day 1, pre-vaccination)., Immunogenicity of TETRALITE with different adjuvant dose levels as determined by: The MN antibody titers in serum samples against the 4 vaccine influenza strains at 7 days, 28 days and 180 days after vaccination versus baseline (Day 1, pre-vaccination).
