Latest research at The University of Calgary, Canada has produced a nanoparticle vaccine for Type 1 diabetes.  The vaccine has been designed to prevent the auto-immune response from causing Type 1 diabetes in children, without causing any harm to immune cells that protect the body against both infection and disease.

The research found that the new nanoparticle vaccine had the ability to cure mice that were already infected with Type 1 diabetes, and also slow the onset of diabetes in mice at risk.  The mice showed no problems with their general immune system, and did not acquire other diseases or infections faster than mice not participating in the study.

If this proves correct, then nanovaccines could be used in auto-immune diseases such as multiple sclerosis and rheumatoid arthritis
