‘Microneedle’ design aims to reduce Covid vaccine shortages

BY Nita Vaidya-Zannino

A low-dose, low cost, hybrid microneedle array designed by collaborators led by Carnegie Mellon University hopes to address Covid-19 vaccine shortages – potentially requiring just 1/100th of the dose of a traditional vaccine.

The microneedle is a new, intradermal delivery device that builds on more than a decade of work on microneedle array technology by Burak Ozdoganlar, professor of mechanical engineering and the project’s principal investigator.

The method is discussed as being pain-free and also has the potential for self administration, helping to speed up the roll-out of Covid-10 vaccine coverage.
