Millions of children around the world aren’t vaccinated, partly because it’s expensive and challenging to get vaccines to kids and keep them safely refrigerated on their long journey. Pharmacist Maria Croyle and her team took inspiration from the sweets in her grandma’s candy dish to figure out a new way to stabilize and store vaccines’ live viruses and other biological medicines. They hope their invention can revolutionize how vaccines are shipped and administered – making it far easier, cheaper and less wasteful to vaccinate people just as the race to stave off the COVID-19 virus gets underway.
