Abstract
Mosaic VLPs of viral capsid proteins from different virus types are described, as are methods of making the same. Specifically, a diploid yeast strain that coexpresses the L1 and L2 capsid proteins of both HPV-6 and HPV-16 as mosaic VLPs is described. The mosaic VLPs induced the production conformational antibodies against both L1 proteins upon administration to mice.
