Dissolving polymer microneedle patches for influenza vaccination

8M Microneedle Drug Delivery Systems, which include Hollow Microneedle and Solid Microneedle technology, offer patient-friendly delivery solutions for vaccines or difficult-to-deliver biologics for particularly needle-phobic patients. By potentially reducing anxiety, microneedle delivery may improve patient compliance in some patient groups.

'Microneedle' Patch Promises Painless Flu Vaccine

Adhesive helps the patch grip the skin during the administration of the vaccine, which is encapsulated in the needles and is released as the needle tips dissolve, within minutes. The patch is peeled away and discarded like a used bandage strip.

A new microneedle patch being developed by the Georgia Institute of Technology and the Centers for Disease Control and Prevention (CDC) could make it easier to vaccinate people against measles and other vaccine-preventable diseases.

About the National Institutes of Health (NIH): NIH, the nation's medical research agency, includes 77 Institutes and Centers and is a component of the . Department of Health and Human Services. NIH is the primary federal agency conducting and supporting basic, clinical, and translational medical research, and is investigating the causes, treatments, and cures for both common and rare diseases.

John McCauley, director of the Worldwide Influenza Centre at the Francis Crick Institute in London, said the research could lead to higher uptake rates of vaccines. “I think it is really quite a promising way forward,” he said, adding that further studies are needed to show that the approach offers benefits in the event of an influenza epidemic.

Access to care is comprised of many things: Are there facilities to get care and providers to give it? Are there excessively long waits or distances to travel to receive care? And is there an available payer for care? Financial access is not sufficient to guarantee physical access to care, but it is necessary. There are several ways the current Senate Bill has an impact on access:

The team plans to conduct further clinical trials to pursue the technology's ultimate availability to patients. They also are working to develop microneedle patches for use with other vaccines, including measles, rubella and polio.

This close-up image shows the microneedle vaccine patch, which contains tiny needles that dissolve into the skin, carrying vaccine. A majority of study participants said they would prefer to receive the influenza vaccine using patches rather than traditional hypodermic needles.

The researchers also are working to develop microneedle patches for use with other vaccines, including measles, rubella and polio.

(a) A permanent magnet is placed about 5 mm below the flexible base substrate and an excess amount of microneedles is dispensed onto the substrate. The ferromagnetic microneedles align along the field lines of the magnetic field perpendicular to the substrate surface. As the magnet is moved laterally, the microneedles follow the magnets and the needles with the bevel facing to the substrate surface get trapped inside the holes. (b) By flipping the magnets upside down, the microneedles that are not trapped in holes rotate and turn the beveled end towards the substrate surface. (c) A metal plate is used to push the microneedles inside the holes. (d) 8D schematic of a fully assembled microneedle patch.
