Needle-Free Vaccines


One hundred sixty years after the invention of the needle and syringe, we’re still using them to deliver vaccines; it’s time to evolve. Biomedical engineer Mark Kendall demos the Nanopatch, a one-centimeter square vaccine that can be applied painlessly to the skin. He shows how this tiny piece of silicon can overcome four major shortcomings of the modern needle and syringe, at a fraction of the cost.

  1. I would like to hear more about the emergence of the nano patch into the field of medicine. Providing immunizations to children & adults can be extremely difficult under the best circumstances. Therefore, I look forward to the day when I can offer my clients improved immunogenicity without the fear of pain.

    • Maryellen, we’ll be sure to keep an eye on the development of this technology.
