| 摘要 |
The present invention provides synthetic vaccine delivery compositions based on polyester amide (PEA), polyester urethane (PEUR), and polyester urea (PEU) polymers for stimulating an immune response to a variety of pathogenic organisms and tumor cells in humans and other mammals. The vaccine delivery compositions are formulated as a liquid dispersion of polymer particles or molecules including class I or class II antigen peptides derived from organism or tumor cell proteins, which are taken up by antigen presenting cells of the mammal to induce an immune response in the mammal. Methods of inducing an immune response to the pathogenic organism or tumor cells in the invention compositions are also included.
