Abstract From the Canadian patent

Improved plasmids and methods for nucleic acid-based vaccines. The use of epitopes, small immunologically relevant protein sequences that are capable of inducing both cellular and humoral responses that result in a protective or therapeutic immune response against large and complex pathogens for incorporation into nucleic acid-based vaccines. The structures and characteristics of gene expression systems that are capable of expressing multiple epitopes. A method of genetic immunization comprising the step of presenting multiple epitopes to an organism in need of said immunization. A plasmid for expression of multiple epitopes comprising a nucleic acid sequence encoding multiple …

Why it's free to use

  • Filed November 9, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 9, 2018.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 9, 2020.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
