Scientists at King's College London for the first time demonstrated their ability to provide life-dried vaccine into the skin without the traditional needle and found this technique is strong enough to activate specific immune cells in the skin.
The technical advancements offer a potential solution to the challenge of providing a live vaccine to some resource-limited countries globally, including India, without the need for refrigeration. A cheaper alternative to syringes, will also eliminate the risk of contamination of needles and pain-free.
"We have found that it is possible to maintain the effectiveness of live vaccines by means of drying the sugar and apply it on the skin by using a micro needle. We also discovered the role of certain cells in the skin that acts as a monitoring system," said Dr. Linda Klavinskis of King College told the Times of India.
This latest discovery involves a silicone mold to make micro needles made of sugar that can be dissolved when inserted into the skin.
