Porcine Rotavirus Reassortant Compositions

Posted Feb 27 2011 7:00pm

Description of Invention:
Rotaviruses are the predominant cause of severe diarrhea and dehydration in infants and young children and are associated with approximately 600,000 deaths each year worldwide. Although death from rotavirus infection occurs more frequently in developing countries an estimated 55,000-70,000 hospitalizations and 20 to 60 deaths occur yearly in the United States. Thus, accelerating the availability of a safe and effective rotavirus vaccine represents a global public health priority.

Available for licensing and commercial development are newly developed human rotavirus-porcine rotavirus reassortant vaccine compositions and methodology for their use in humans. This technology provides immunogenic compositions of reassortant human-porcine rotaviruses with VP7 specificity of the most clinically prevalent serotypes of human rotavirus found in various regions of the world. These compositions, which need clinical evaluation, should be able to induce an immunogenic response specific to human rotavirus serotypes that is protective against symptoms of serious rotaviral disease, such as severe diarrhea and dehydration. Porcine rotaviruses are genetically more closely related to human rotavirus strains compared to rhesus and bovine rotaviruses.

  • Resistance to developing severe human rotaviral disease
  • Safe and effective global infant vaccinations
