    Abstract: The present invention provides rotavirus reassortant immunogenic compositions based on a porcine rotavirus. In particular, porcine rotavirus Gottfried strain-based single VP7 or VP4 gene substitutions which can provide (i) an attenuation phenotype of a porcine rotavirus in humans and (ii) antigenic coverage for G serotypes 1, 2, 3, 4, 5, 6, 8, 9 and 10 and P serotype 1A[8], 1B[4] and 2A[6]. The compositions have been demonstrated to induce consistent levels of neutralizing antibodies against rotavirus specificities which are of global epidemiologic importance. Porcine rotavirus-based reassortant rotavirus compositions induce neutralizing antibodies against P1A[8] and P2A[6] VP4 serotypes which may provide an advantage over rhesus- or bovine-based reassortant vaccines since the VP4s of the latter vaccines do not evoke antibodies capable of neutralizing the P1A[8], or P2A[6] VP4.

    Abstract: The present invention provides compositions for making a medicament and methods for the administration of a vaccine compositions for protection against human rotaviral disease without significant reactogenicity. Human x rhesus reassortant rotavirus compositions were made which when administered during the first 7 to about 10 days of life, provided a composition which was non-reactogenic followed by booster immunizations at 16 to 18 weeks or 14 to 20 weeks, up to 1 year of age. The immune response induced by the initial neonatal administration of the live rotavirus vaccine composition protects the infant from the reactogenicity of the composition when administered as a second vaccine dose at or after 2 months of age. Administration of the immunogenic composition also is expected to ablate or significantly diminish the increase in the excess of intussusception observed 3 to 7 days following administration of the initial dose of rotavirus vaccine at about 2 to 4 months.
