DNA vaccines against rotavirus infections

Abstract

This invention relates to methods of eliciting an immune response and/or protective immunity in a vertebrate by introducing into the vertebrate a DNA vaccine which consists essentially of DNA encoding an antigen or antigens, e.g., capsid proteins or polypeptides, of rotavirus. The uptake of the DNA vaccine by a host vertebrate results in the expression of the capsid protein, thereby eliciting humoral or cell-mediated immune responses, or both, which can provide protection against infection and/or prevent clinically significant rotavirus-caused disease. In addition, the invention demonstrates that an internal vital antigen provides protective immunity in a host. The host can be any vertebrate, including birds, piglets, and humans.
