3D vaccine patch shows promise

In a study conducted on animals, the immune response was comparably different when jabbed.

Published in the Proceedings of the National Academy of Sciences the 3D-printed microneedles are lined on a polymer patch, which is barely long enough to reach the skin and inject the vaccine. The patches absorbs into the skin and can easily be shipped and handled hassle-free.

Joseph M. DeSimone, lead study author and entrepreneur in 3D print technology said: “In developing this technology, we hope to set the foundation for even more rapid global development of vaccines, at lower doses, in a pain- and anxiety-free manner.”

The vaccine patch is not only easy and effective but is also painless, less-invasive and can be self-administered. The patch saves doses as compared to needle and syringe vaccines, due to their effectiveness.

In the study, it was noted the patch generated a significant T-cell and antigen-specific antibody response, which was 50 times greater than a subcutaneous injection.

Using 3D printing, vaccine patches can be customised and developed for flu, measles, hepatitis or Covid-19 vaccines.
