First Human Trial of Fridge-Free Vaccine Shows Promise for Global Health

Scientists in the UK have published results from the first human trial of a tetanus-diphtheria vaccine that does not require refrigeration. Published in eClinicalMedicine, part of The Lancet group, the study describes a vaccine reformulated with trehalose sugar, which remained stable at room temperature for a year. This breakthrough could significantly improve vaccine distribution and reduce waste, particularly in remote areas with unreliable power and refrigeration.
