The end of injections
View(s):It could finally mean the end of painful injection, and instead deliver a powerful new type of vaccine through a stick on ‘tattoo’. Researchers say patches covered in ‘microneedles’ may be a far safer, and less painful, way to deliver a new generation of vaccines.
They claim the system could even be used to deliver DNA vaccines for ‘risky’ disease such as HIV. Applying patches loaded with these needles onto the skin instantly embeds the coatings into the body, much like the application of a tattoo.
These microneedles can be designed to disrupt only the most superficial layers of the skin to avoid nerve endings and blood vessels, making them painless and safer than hypodermic needles.
The microneedles are set to be used to deliver a new generation of ‘DNA vaccines’ the researchers say.
