This invention is directed to a vaccine for the prevention of disease caused by Bordetella pertussis which comprises the pertussis antigens filamentous hemagglutinin, detoxified lymphocytosis promoting factor and a 69 kilodalton outer membrane protein, where said antigens are individually purified prior to being combined to form the vaccine. The invention is further directed to pertussis vaccines where the antigens are combined in any ratio, including ratios not possible in whole cell or co-purified acellular pertussis vaccines. The pertussis antigens may be further combined with other individually purified pertussis antigens, pertussis structural components, adjuvants, stabilizers and non-pertussis vaccine components.

This invention discloses a process for preparing an acellular Bordetella pertussis vaccine by passing culture supernatants or cellular extracts of B. pertussis through a column containing an ion exchange resin. The eluate from the column is detoxified and can then be employed by conventional means as a vaccine. The vaccine so produced has reduced toxicity due to the removal of endotoxin.
