The present invention relates to foreign peptide sequences fused to recombinant plant viral structural proteins and a method of their production. Fusion proteins are economically synthesized in plants at high levels by biologically contained tobamoviruses. The fusion proteins of the invention have are useful as antigens for inducing the production of antibodies having desired binding properties, e.g., protective antibodies, or for use as vaccine antigens for the induction of protective immunity against the parvovirus. Feline parvovirus epitopes were fused to the N-terminus of the TMV coat protein, expressed inplants, extracted, purified, characterized and administered to animals, resulting in protective immunity.
