Text: Geometric mean titer in the female 18 - to 49-year age group exceeded male responses for all strains : responses to half-dose TIV that were comparable with male full-dose responses for A/New Caledonia/20/99 (A/H1N1) antigen, 25. 4 (95 % CI, 20. 9-30. 9) vs 25. 6 (95 % CI, 21. 3-30. 9) ; A/H3N2 antigen, 60. 8 (95 % CI, 50. 8-72. 7) vs 44. 1 (95 % CI, 37. 6-51. 8) ; and B antigen, 64. 4 (95 % CI, 53. 9-76. 9) vs 60. 7 (95 % CI, 51. 4-71. 7) (findings were similar for the 50 - to 64-year age group).
