Half of vaccines are binned – ‘fridge-free’ versions could change that

• Approximately 50% of vaccines are discarded due to cold-chain failures, representing significant waste and financial loss in vaccination programmes
• Researchers have successfully developed room-temperature stable vaccine formulations that maintain efficacy for up to one year without refrigeration
• Fridge-free vaccines could substantially improve vaccine accessibility in resource-limited settings and reduce wastage, potentially transforming global immunisation coverage

Scientists have kept vaccines stable at room temperature for a year, which could transform global vaccination.
