Individual immune responses to BPZE1 vaccination in culture positive volunteers.

Concentrations of anti-PT, anti-FHA, anti-PRN and anti-FIM serum IgG in culture positive volunteers over time. Results are given in IU/ml.
An increase is considered significant (bold numbers) if antibody level is doubled compared to pre-vaccination level and at least four times the minimum level of detection (4 IU/ml for PT and FHA, 8 IU/ml for PRN, and 4 EU/ml for FIM).
