Reconstituted Newcastle disease virus envelopes as a split vaccine.
Isolated envelope proteins of Newcastle disease virus (NDV) were inserted into the lipid bilayer of artificial vesicles to create a viral envelope-like structure. The structure-containing viral antigens at high density elicited a strong immune response, in contrast to purified viral proteins. The artificial envelopes or immunosomes possessed several advantageous properties when used as vaccines. They elicited a faster response and the immunity lasted longer in animals treated with these vesicles than in controls vaccinated with envelope proteins in combination with traditional adjuvants. A further useful feature of the artificial envelopes is that no inflammatory lesions develop at the site of their injection.
