Abstract From the Canadian patent

The present invention provides vaccine compositions for protection against human rotaviral disease without significant reactogenicity. Human x bovine reassortant rotavirus comprising each of the four clinically most important VP7 serotypes of human rotavirus are combined in a multivalent formulation which provides a high degree of infectivity and immunogenicity without producing a transient febrile condition. Methods for producing an immunogenic response without producing a transient febrile condition are also provided.

Why it's free to use

  • Filed July 27, 1999 and granted January 7, 2014. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 27, 2019.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 27, 2021.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
