A tetanus-diphtheria vaccine that doesn’t need a fridge has passed its first human trial. UK scientists reformulated a licensed shot using trehalose, the sugar that lets desert plants survive without water, keeping it stable for up to two years at 30°C. In a trial involving 60 adults it matched two approved vaccines on safety and immunity. Gavi https://www.gavi.org/vaccineswork/fridge-free-vaccine-passes-first-human-trial-raising-hopes-hardest-reach
