| novel antigen delivery systems. | vaccines represent the most relevant contribution of immunology to human health. however, despite the remarkable success achieved in the past years, many vaccines are still missing in order to fight important human pathologies and to prevent emerging and re-emerging diseases. for these pathogens the known strategies for making vaccines have been unsuccessful and thus, new avenues should be investigated to overcome the failure of clinical trials and other important issues including safety concern ... | 0 | 26279977 |
