    Abstract: Inactivated scours vaccines for immunization and protection of bovine animals from disease caused by infection with bovine rotavirus and bovine coronavirus, which comprise and effective amount of at least one inactivated viral strain are described. Polyvalent inactivated vaccines further comprising an effective amount of an antigenic component which is protective against one or more additional pathogenic organisms or viruses are also disclosed. Said vaccines are prepared from one or more strains of rota- and coronavirus, C. perfringens Type C bacteria and E. coli bacteria, and combinations thereof. Preferably, a polyvalent inactivated vaccine is provided for parenteral administration. Passive immunity is achieved in neonatal calves via immunization of pregnant cows prior to birth.

    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. Humannullrhesus reassortant rotavirus compositions were made which when were 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 dose at or after 2 months of age. Administration of thee immunogenic composition also is expected to ablate or significantly diminish the increase in the excess of imussusception observed 3 to 7 days following administration of the initial dose of rotavirus vaccine at about 2 to 4 months.

    Abstract: Defined serum-free, low protein media (LPKM), that supports 1) Vero cell growth for up to 20 passages, 2) Vero cell growth on microcarriers and 3) rotavirus production is provided. Maximum cell densities attained are 60-100% of that in serum-containing medium; the doubling time is equal to that for cells in serum containing medium. Rotavirus titers achieved in LPKM-1 are 50-100% of the serum-containing process. Finally, since LPKM-1 contains no animal-sourced proteins, the problems associated with the serum-containing rotavirus production process (i.e. lengthy wash steps before infection, potential introduction of adventitious agents and lot-to-lot variability) can be avoided; while maintaining nearly equivalent product titers.
