The encouraging results of the world's first trial of a fridge-free tetanus-diphtheria vaccine could improve access worldwide to crucial treatments while reducing carbon emissions. Fridge-free vaccines have the potential to transform vaccine delivery by reducing dependence on refrigeration. This would improve access in more isolated communities and cut the environmental impact by reducing energy use and emissions.

Around half of vaccines are wasted each year globally, according to the World Health Organization. Many are lost because they get too hot or cold. The scale of the loss prompted scientists to work on fridge-free versions of common vaccines - and this week one such vaccine showed promise in a world-first trial.
