Room Temperature Vaccines Pass First Human Trial
A UK company has tested fridge-free vaccines on people for the first time. Stablepharma gave 60 volunteers a tetanus-diphtheria vaccine that had been stored as a dry powder at room temperature for a year before being mixed with water and injected. The technology copies resurrection plants, which make a sugar called trehalose to protect their cells during droughts. The National Institute for Health and Care Research funded the work.
Half of all vaccines are wasted each year because they get too hot or too cold during storage and transport. Temperature-stable vaccines could end that waste, particularly in poor and remote areas where refrigeration is scarce.
