Fridge-free vaccines could slash global waste, UK trial shows
UK NIHR trial shows a dry-powder, trehalose-stabilised tetanus–diphtheria vaccine that can be stored at room temperature and still elicit an equivalent immune response, potentially removing cold-chain needs and reducing wastage; a larger 160-person trial is planned, with potential applicability to other vaccines and some medicines, though not all (e.g., mRNA).
