Tiny Sugar-Covered Bandaid Could Replace Needles For Vaccinations
Scientists at King's College London have developed a new way to administer vaccines, using a pain-free microneedle array.
Scientists at King’s College London have developed an injection-free vaccination that administers a dried live vaccine to the skin. The microneedle array is a small disc with lots of tiny needles made of sugar that dissolve when inserted into the skin, meaning less pain.
The dried microneedle vaccine was found to generate the same immune response as an injected liquid vaccine preserved at -80°c. As the dried live vaccine remains stable and effective at room temperature, it could eliminate the need for refrigeration.
