Fridge-Free Tetanus-Diphtheria Vaccine Shows Promise of Reaching Millions Worldwide

Fridge-free tetanus-diphtheria vaccine shows promise of reaching millions worldwide

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.

Phase 1 results from ‘fridge-free’ tetanus-diphtheria vaccine

Scientists are publishing phase 1 results from a trial of the world’s first fridge-free vaccine – a tetanus-diphtheria vaccine, developed to be able to be stored at temperatures of up to 30°C rather than kept in the fridge as vaccines usually are. Around half of vaccines are wasted globally each year because of temperature changes during storage and transport. If fridge-free vaccines could be developed they could have the potential to reduce dep…
