Scientists have developed a new type of nano particle which they say can safely and effectively deliver vaccines for diseases such as malaria and HIV-AIDS.

Developed by a team from the Massachusetts Institute of Technology (MIT), the new particles consist of concentric fatty spheres that can carry synthetic versions of proteins normally produced by viruses.

These synthetic particles, the researchers said, elicit a strong immune response, comparable to that produced by live virus vaccines, but should be much safer.
