A new vaccine principle is being developed by scientists at the University of Copenhagen which if it works to its full expected potential could help to save millions of lives and revolutionise current vaccine technology. The ‘InVacc’ platform, as it is known, represents an advance on the original DNA vaccines and generates new vaccines with greatly enhanced properties. The platform consists of a chain of amino acids attached to a gene of the virus being vaccinated against.

This is the first report linking aluminium overload with either of the two conditions and the possibility is considered that the coincident aluminium overload contributed significantly to the severity of these conditions in a patient.
