Genetic material can’t simply be injected into the body on its own – it would have no way of entering our cells, where it needs to be in order to have its intended effect. By delivering DNA or RNA, gene therapies can allow cells to build proteins that they lack the ability to build, block the production of a harmful protein, or guide ‘genetic scissors’ to cut diseased genes out of the genome. Rather than trying to treat a disease with drugs, which can bind to receptors on the surface of a cell and set off a cascade of effects with undesirable consequences, gene therapy tells the cell exactly what to do using the language of life: the genetic code. Gene therapy has the potential to revolutionise medicine because of the precision of its effects. After being seemingly stuck in limbo for decades, gene therapy technology suddenly went from being relegated to treating a handful of rare conditions, to being put into vaccines that would be taken by billions.
