Wow of the Week: A flu vaccination you could give yourself, with no shots involved | MedCity News

Very cool, and a great use of microfabrication technology. This microneedle array delivers its vaccine payload painlessly into the skin and the needles dissolve. Perhaps your healthcare insurer will mail your vaccine to you in the not too distant future.

The microneedle array (still in the animal research phase) could be an important tool for vaccine delivery in developing countries where vaccine doses must be transported to remote populations and refrigeration equipment is not readily available. And perhaps it will increase the participation in flu and other vaccine programs by people who have needle and/or pain phobias.

I’m aware of at least one other company commercializing a microneedle-based medical product. The startup company is Kitotech, based in Seattle, and they have developed a product called Kitostitch. The Kitostitch product is intended to replace steri-strips for primary wound closure. The value proposition is a little less clear in that case. In my experience, it’s tough to oust incumbent technology even if it’s mediocre, when there’s no nagging problem being solved.

Takeaways: There are plenty of unsolved medical problems, some big and some small, that can benefit from smart innovation. The technology of vaccine injection would seem to have been perfected or at least exhausted of innovation but these researchers created a completely new inoculation technology. Complacency is the enemy of innovation. Do not ever assume that a “better mousetrap” cannot be designed for a particular need. Most important is that you keep looking for unsolved problems and unmet needs.
