A cloned DNA fragment of Bordetella pertussis including the gene which codes for the pilinic subunit fim3 vectors which contain it and microorganisms transformed by the vectors. The protein and peptides corresponding to at least one epitope of the gene which codes for the pilinic subunit fim3 are particularly useful for the development of acellular anti-pertussis vaccines. In addition a strain of Bordetella modified by, a recombinant replication or genome-integration vector containing the cloned DNA fragment or the gene or a fraction thereof is particularly suitable for the development of a cellular anti-pertussis vaccine.

Why it's free to use
- Filed September 21, 1990 and granted May 29, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 21, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 21, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
