Edible Vaccines don't need Refrigeration

Mar-06-20 Vaccines need to be kept cool to be effective which is a challenge in remote or developing areas, but scientists have discovered a new way to preserve the live elements in a lightweight film that doesn't need refrigeration.

After more than 450 attempts, the team landed on a recipe enabling the virus to be loaded into a candy-like material with protective layers that can be peeled off when it's time to use them.

They have developed a vaccine for influenza at a proof-of-concept level, and believe it could be used to deliver a vaccine for COVID-19 when it is ready to distribute.

As well as being low-cost, the product is one-thousandth the size of traditional vaccine vials and can be taken orally, avoiding the millions of syringes, vials and packaging waste currently used in traditional vaccine methodology.
