1 Figure 1 Protective effects of acellular pertussis vaccines (A–F) in the respiratory infection model. Mice were challenged by exposure to an aerosol of B. pertussis strain 18–323. Mouse lungs were removed 14 days after the challenge and bacteria in the lungs were counted. Results are presented as CFU, and are mean values per lung, as estimated from individual lungs of five mice. STD, standard pertussis vaccine (whole-cell pertussis vaccine). Each column with a vertical line represents a mean and standard error. *P<0.05 versus the control group.

2 Figure 2 Protective effects of acellular pertussis vaccines in the intracerebral challenge model. Mice were challenged, 21 days after immunization, with B. pertussis strain 18–323 which was introduced intracerebrally. The mice were observed for 14 days (see Section 2 for details).

Figure 4 Levels of antigen-specific IgG in the serum of immunized mice. Sera from control mice (Saline) and immunized mice (A–F and STD) were examined by ELISA. Levels of antibodies (anti-PT, anti-FHA, anti-PRN and anti-Fim) were expressed as EU ml<sup>−1</sup>. Each column with a vertical line represents the mean and standard error of results from individual samples of serum from five mice in each group. STD, standard pertussis vaccine (whole-cell pertussis vaccine).

5 Figure 5 Secretion of IFN-γ by spleen cells in vitro in response to vaccine components as antigens. Spleen cells were prepared from control mice (Saline) and immunized mice (A–F and STD). The results represent mean concentrations of IFN-γ, as estimated from individual cultures of spleen cells from five mice in each group. Each column with a vertical line represents a mean and standard error of results from individual samples of spleen cells from five mice in each group.
