Liposomes - Hollow Nanospheres for Vaccines - Medical / Health Care - Pharmaceuticals

Antigens can be carried by liposomes, either lipids, proteins, DNA or RNA. They can also be combined with bacteria or virus components to form archaeosomes or virosomes, respectively. These vaccines have been proved to be effective in inducing immune responses and providing a sustained exposure to the antigen. More than 30 clinical trials are currently using liposomes for vaccine delivery including HIV and several types of cancer.
