The reuse of needles to administer vaccines is a source of infection all over the world, so new technology that reduces this risk is essential.

By incorporating antibacterial silver nano-particles into the dissolvable microneedles the researchers believe they have created a promising vehicle for safe vaccine delivery around the world.
