Researchers at the Massachusetts Institute of Technology (MIT) have developed a new tool for vaccination that could allow providers to deliver multiple doses of a medication or vaccine in one shot.

The discovery, outlined in a report published in Science, uses a three-dimensional fabrication method where microparticles are filled with a drug or vaccine and then sealed. The microparticles are created using a biocompatible, FDA-approved polymer that will dissolve at specific times, allowing delivery of its contents. This delivery method could result in short bursts of medication or vaccine delivered at particular intervals, mimicking the timing of a vaccine series.

Kevin J. McHugh, PhD, a postdoctoral student working in the Langer Lab at the Koch Institute for Integrative Cancer Research at MIT, told Medical Economics the technology is still in the early stages, but he envisions it to enable clinicians to deliver a full component of vaccines in a single shot.
