Abstract
Novel methods and compositions are provided for vaccinating a host susceptible to viral infection. Particularly, an initial injection is employed of one or more polypeptides associated with the host immune response to the pathogen followed by administration of the pathogen in attenuated form, particularly having a deletion associated with the gene expressing at least one of said polypeptides. In this manner, hosts may be vaccinated so as to maintain a strong defensive posture against infection from the pathogen. The method is specifically illustrated with feline leukemia virus.
