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.

Abstract: The present invention relates to attenuated, immunogenic West Nile virus chimeras built on a dengue virus backbone for the production of immunogenic, live, attenuated West Nile virus vaccines.

Abstract: A live, attenuated chimeric virus vaccine against tick-borne encephalitis virus comprising the preM and E structural genes of the tick-borne encephalitis Langat virus and the non-structural genes of the mosquito-borne dengue virus. The live chimeric vaccine was administered intraperitoneally and exhibited complete attenuation in mice while at the same time providing protection against subsequent challenge with the virulent parental Langat virus.

Abstract: A new immunotherapeutic method of treating lower respiratory tract infection caused by respiratory syncytial virus (RSV) is disclosed. The method employs topical application of RSV antibodies into the lower respiratory tract. The new treatment modality is more effective and rapid than the conventional therapy.
