Plant Could Reduce Vaccine Waste

UK scientists have successfully tested a "fridge-free" tetanus-diphtheria vaccine, which can be stored at room temperature without refrigeration, potentially reducing vaccine waste caused by temperature fluctuations during transport. The trial involved drying the vaccine with trehalose, inspired by resurrection plants, and demonstrated comparable immune responses and safety in early studies. This development could improve vaccine access in remote and resource-limited areas by eliminating reliance on the cold chain, with larger trials planned to confirm stability across varying conditions.
