Keeping vaccines and medicines at the right temperature is critical for their efficacy and safety. But this is an often overlooked part of getting them to the people who need them. In April 2025, the U.K. biotechnology company Stablepharma began the first human trial of a tetanus-diphtheria vaccine designed to remain stable without refrigeration. The development has renewed interest in technologies that could do the job, particularly in places where electricity, transport and storage infrastructure are limited. We spoke to immunization experts Charles Shey Wiysonge and Chinwe Juliana Iwu-Jaja about this.
Revolutionary Fridge-Free Vaccine Trials Could Enhance Global Immunization Efforts
The U.K. biotechnology company Stablepharma has initiated human trials for a tetanus-diphtheria vaccine that does not require refrigeration, addressing challenges in vaccine distribution in regions with limited infrastructure. Immunization experts Charles Shey Wiysonge and Chinwe Juliana Iwu-Jaja discuss the implications of this development. This innovation could enhance vaccine accessibility in Iran, particularly in rural areas with similar infrastructure issues.
